 Hello.  Why are you reading this file?  This is tack's help
file.  The format is fairly simple.  the "hs" code indicates
a help section.  The two numbers that follow are the level
and the section.  These are organized in a hierarchical fashion,
so that help for higher levels are immediately after the lower
levels.  Oh well, it's easier for you to figure it out than it
is for me to explain it.  The boh indicates the "beginning of
help" code and the eoh is the "end of help" code.  Anything
between these markers will be displayed by Tack for that help
level and section, so feel free to add more if you need to.

------------------- Load File ------------------
hs:1:1:Load File
boh
  This allows you to load a file
into one of Tack's Buffers.
Tack reads and automatically
identifies files written by
Patchit, Clampex (> v. 5.0),
Fetchex and Ninja.
eoh

hs:2:1:List Files
boh
  All files with the extension ".dat" in
the current directory will be shown.
A file may be cursor selected
from this box or else the name of a
parameter file may be typed in (do not
type the ".dat" extension).  To change
directories, type the F2 key (or else
click the left mouse button in the upper
window) and then type the name of the
desired directory.  The list of data
files will be updated for this new directory.
eoh

hs:2:2:Which Buffer
boh
  Choose the buffer into which the contents
of the data file will be loaded.  If you
choose an already loaded buffer, its contents
will be overwritten.

the date & time of the file from which
this data originated, or alternatively
to give it the current date and time.
eoh

--------------------- Export ---------------------
hs:1:3:Export
boh
  This allows you to export the binary
(numerical) data from Tack in either Ascii
or Asystant format.
  Note: For exporting data traces,
Plot the data traces to a file.
eoh

hs:2:1:Buffer
boh
  Select the Buffer from which you want
to export data.  The contents of only one
buffer at a time may be exported.
eoh

hs:2:2:Channel
boh
  Select the channel from which you want
to export the data.
eoh

boh
  Select the range of time in the data records
within which data will be exported.  The timing
can be selected numerically or by cursor selection.
eoh

hs:2:5:Format
boh
  Select the format the exported data file
will be written in.  Two formats are
available, Ascii and Asystant.
  Ascii format data files can be read by many
programs, including spreadsheets.  The data is
arranged in the files as a series of columns,
one column for each record.  If you choose to
use X axis data, this will be in the first
column.  Columns are separated (or delimited)
by any character you choose.  The comma or
space characters are commonly used.
  Asystant format data files can be read by
Asystant rev 1.10 (but may be readable by
other revs).  The file is written in a
binary format.  An X axis cannot be used.
eoh

hs:3:1:Ascii
boh
  Ascii format data files can be read by many
programs, including spreadsheets.  The data is
arranged in the files as a series of columns,
one column for each record.  If you choose to
use X axis data, this will be in the first
column.  Columns are separated (or delimited)
by any character you choose.  The comma or
space characters are commonly used.
eoh

hs:3:2:Asystant
boh
  Asystant format data files can be read by
Asystant rev 1.10 (but may be readable by
other revs).  The file is written in a
binary format.  An X axis cannot be used.
eoh

hs:2:6:X Values
boh
  Select the format for the values which would
be the X Axis values.  These are the first column
of data in an Ascii file.  This option is not
supported for files exported in Asystant format.
The X values can be either the time at which the
data point occurred, the point number of the data
occurred or none.
  Time: The value for the X axis is the time at
which the point occurred (in milliseconds).
  Point #: The value for the X axis is the point
number corresponding to the data point.
  None: No value is written to the file for the
X axis
eoh

hs:3:1:Time
boh
  The value for the X axis is the time at which
the point occurred (in milliseconds).
eoh

hs:3:2:Point #
boh
  The value for the X axis is the point number
corresponding to the data point.
eoh

hs:3:3:None
boh
  No value is written to the file for the X axis
eoh

hs:2:7:Y Values
boh
  Select the format for the numerically exported
data.  The data can be either in real values (the
true, physical value of the data, or in 12-bit
format which is the form in which the data was
recorded by the data acquisition card.
  Real Values: The values for the data points are
written as their true, physical value.
  12 Bit Data: The values for the data points are
written as they were recorded by the data
acquisition card, in 12 bit format with values
from -2047 to 2048.
eoh

hs:3:1:Real Values
boh
  The values for the data points are
written as their true, physical value.
eoh

hs:3:2:12 Bit Data
boh
  The values for the data points are
written as they were recorded by the
data acquisition card, in 12 bit
format with values from -2047 to 2048.
eoh

hs:2:8:Sample
boh
  This allows you to have Tack not export
all of the data points, instead you can
have it select every 2nd, 3rd, 4th data
point etc.
eoh

hs:2:9:Go
boh
  This causes the operation to occur,
and data is exported.
eoh

hs:3:1:Select Timing
boh
  Select the timing range within the data
records that will be exported.  Type the ESC
key to cancel this operation.
eoh

hs:3:2:File Name
boh
  Name the file to which the exported
data will be written.  If the export
format is Ascii, this file will be
written in Ascii (text) format.  If
the export format is Asystant, this
file will be binary.
eoh

hs:2:10:Quit
boh
  This cancels the operation.
(Data is not exported)
eoh

------------------- DOS Shell ------------------
hs:1:4:DOS Shell
boh
  This allows the user to temporarily
exit to DOS to perform simple commands.
In order to allow this, Tack "spawns"
a copy of the DOS command interpreter.
Note that Tack is still loaded in
memory so there will be less DOS memory
available to execute a command.
Type "EXIT" at the DOS command line
("C:\>") to return to Tack.
eoh

------------------- Plot ------------------
hs:1:5:Plot
boh
  This allows you to make hardcopies of
data traces.  Plotting/printing goes to
the currently selected printer (which may
be a file, thus allowing you to export
data traces in graphical format).  Tack
uses what is displayed on the screen as
its model for what to print.  So, if
nothing is on the screen, nothing will
be printed.
eoh

------------------- About ------------------
hs:1:6:About
boh
  Displays information about Tack.
This includes memory usage, information
about the author and most importantly,
information about the data stored in
the various buffers.
eoh

hs:2:1:Data
boh
  Displays information about data stored in
Tack's buffers.  If more than one buffer are
loaded, you will first be prompted for the
buffer whose data you are interested in.
Oh, by the way.  You can get the about data
menu to come up (about the currently
selected buffer) when you are at Tack's main
level (when no menus are down) by typing the
"?" key.
eoh

hs:3:1:Inputs
boh
  Displays info about how the data was
recorded, this includes the number of
records, channels, etc.  The sampling
interval, the program (and rev.) that
recorded the data, mapping of the
original channel assignment to that
used by Tack.
eoh

hs:3:2:Outputs
boh
  Displays info about the states of the
outputs used when the data in the buffer
was acquired.  The various possible
outputs (D/A, Binary) are listed one
by one, with the outputs waveform described
as a series of events, each event shows
what sort of transition happened at the
time shown.
eoh

hs:3:3:Gain List
boh
  Displays the list of the gains for all
the channels and all the records.  If
these are set incorrectly they can
be changed using Buffer/Modify/Gains.
eoh

hs:3:4:Comments
boh
  Displays any comments recorded
with the data file.
eoh

hs:2:2:Memory
boh
  Displays information about memory
usage by Tack.  There are three types of
memory used by Tack:
  Conventional Memory:  This is the memory
used by all DOS real mode programs, it is
limited to a maximum of 640 KB.  Tack will
show you the total amount of conventional
memory on your computer and the amount that
is currently available.
  XMS memory: This is memory above the 1
Megabyte boundary that can be accessed
by Tack if an XMS driver (such as
Microsoft's HIMEM.SYS) is loaded.  XMS
memory allows Tack to store many data
buffers without filling up the DOS
(conventional) memory area.  If XMS is
available Tack will store Data buffers
in it unless you have disabled this
feature (see below,
Config:Other Options:XMS).
  Disk Memory: This is the memory available
on the disk.  Tack shows the total disk
space and the available amount on the
current disk.
eoh

hs:2:3:Tack
boh
  Displays information about Tack and
it's author.  Mainly this is for the
copyright notice and to show you where
you can reach me, to complain about
things, request features or to heap
praise and money.
eoh

hs:2:4:Quit
boh

  - Average  - Averages the contents of two buffers
eoh

------------------- Copy Buffer ------------------
hs:1:1:Copy Buffer
boh
  This allows you to copy the contents of one
data buffer into a new or existing buffer.  If an
existing buffer is copied to, the data in it will
be overwritten
eoh

hs:2:1:Source Buffer
boh
  This is the buffer whose contents will
be copied to the destination buffer.
eoh

hs:2:2:Destination Buffer
boh
  This is the buffer to which the contents
of the source buffer will be copied.  If
the destination is an existing buffer, its
contents will be overwritten.
eoh

hs:2:3:Go
boh
  This causes the copy operation to occur
eoh

hs:2:4:Quit
boh
  This cancels the copy operation
eoh

------------------- Delete ------------------
hs:1:2:Delete
boh
  This allows you to delete things from Tack.
You can delete the contents of all or just a
single data buffer, a channel of data in a
buffer, or some records of data in a buffer.
eoh

hs:2:1:Buffer
boh
  This allows you to delete the contents of a
single buffer from Tack's memory.  The data
file itself (stored on the hard disk) is not
affected.
eoh

hs:2:2:All Buffers
boh
  This allows you to delete the contents of
all buffers that are currently loaded in Tack's
memory.
eoh

hs:2:3:Channel
boh
  This allows you to delete a single channel
of data from the currently selected buffer.
If the buffer has only one channel of data,
then the entire buffer will be deleted.
eoh

hs:2:4:Records
boh
  This allows you to delete a selectd range
of data records from the currently selected
buffer.  If you delete all of the records,
then the entire buffer will be deleted.
eoh

hs:2:5:Quit
boh
  This exits this menu
eoh

------------------- Modify ------------------
hs:1:3:Modify
boh
  This allows you to modify things in Tack.
You can change the sampling interval for data
in a given buffer, the timing of data, the
gain used for recording the data, or change
the data itself.
eoh

hs:2:1:Sampling Int
boh
  This allows you to change the sampling
interval for the current buffer.  This is
useful for decreasing the number of data
points in a record for exporting graphical
traces.  The new sampling interval must be
an integer multiple of the original
sampling interval.
eoh

hs:2:2:Timing
boh
  This allows you to change the timing of
the data in the current buffer.  Timing
may be selected either numerically or
graphically.
eoh

hs:3:1:Graphical
boh
  Graphically select the new timing with the
cursor keys or mouse.  When done setting one
cursor, hit the enter key.  Cursor selection
may also be done with the mouse (click & drag)
hit the right mouse button to drop a cursor.
eoh

hs:2:3:Gain
boh
  This allows you to change the gain for the
data in the current buffer.
eoh

hs:2:4:Data
boh
  This allows you to modify the data in a
buffer.
eoh

hs:3:1:Buffer
boh
  This is the buffer whose data you want
to modify.
eoh

hs:3:2:Channel
boh
  This is the channel for the selected buffer
whose data you want to modify.
eoh

hs:3:3:Records
boh
  This is the range of records, for the
selected channel, in the selected buffer,
for whose data you want to modify.
eoh

hs:3:4:Operation
boh
  This is the operation you want to perform
on the selected range of records (on the
selected channel, in the selected buffer).
  The operations are multiply, divide, add,
subtract, and separate records.  The first
four all perform the indicated operation on
the selected data, using a user-entered
factor.  The separate recs operation
separates the selected records by a factor.
This is useful for offsetting data for
display purposes.
eoh

hs:4:1:Multiply
boh
  The selected data is multiplied by the
user-specified factor.
eoh

hs:4:2:Divide
boh
  The selected data is divided by the user-
specified factor.
eoh

hs:4:3:Add
boh
  A user-specified factor is added to
the selected data.
eoh

hs:4:4:Subtract
boh
  A user-specified factor is subtracted from
the selected data.
eoh

hs:4:5:Separate Recs
boh
  The selected records are separated (individually
offset) by a user-specified factor.
eoh

hs:5:1:Factor
boh
  This is the factor which is combined with
the data records.  For multiply and divide
operations, this is a floating point number.
For add, subtract and separate operations,
this is an integer.  Since the raw data is
typically in the range -2047 -> 2048, this
is a typical range of integer factors.
eoh

hs:5:2:Gain Comp
boh
  This feature should typically be on.  It
compensates the gain of the data when you
multiply or divide the data by a factor.
A time when you might not want to use this
feature would be if you had added together
a number of buffers and then were dividing
them by a factor in order to average them.
I realize that the addition operation should
be handling the gain properly and that will
come to be in the future.  - gbg.
eoh

hs:3:5:Go
boh
  This causes the operation to occur
eoh

hs:3:6:Quit
boh
  This exits this menu
eoh

hs:2:5:Quit
boh
  This exits this menu
eoh

------------------- Add ------------------
hs:1:4:Add
boh
  This allows you to add together the
contents of two buffers.  If the contents
if the buffers have differing numbers of
channels, records or differing timing,
then the result of the operation will be
a buffer with the smaller values of these.
(i.e. if A has 8 records and B has 6, then
the result will have 6 records.)
Note: At this point these operations don't check
the gains of the data, make sure your data is all
at the same gain
eoh

hs:2:2:Addend
boh
  This specifies one of the two buffers whose
contents you wish to add together
eoh

hs:2:3:Destination
boh
  This specifies the destination buffer, into
which the results of the addition will be put.
If a buffer is specified which already contains
data, then its contents will be overwritten.

eoh

hs:2:5:Cancel
boh
  This cancels the operation,
the buffers are not added.
eoh

------------------- Subtract ------------------
hs:1:5:Subtract
boh
  This allows you to subtract the contents
of two buffers.  If the contents if the
buffers have differing numbers of channels,
records or differing timing, then the result
of the operation will be a buffer with the
smaller values of these. (i.e. if A has 8
records and B has 6, then the result will
have 6 records.)
Note: At this point these operations don't
check the gains of the data, make sure your
data is all at the same gain

boh
  This specifies the buffer which will be
subtracted from the other buffer (the
subtractor).
eoh

hs:2:3:Destination
boh
  This specifies the destination buffer, into
which the results of the subtraction will be put.
If a buffer is specified which already contains
data, then its contents will be overwritten.

eoh

hs:2:5:Cancel
boh
  This cancels the operation,
the buffers are not subtracted.
eoh

------------------- Average ------------------
hs:1:6:Average
boh
  This allows you to average the contents
of two buffers.  If the contents if the
buffers have differing numbers of channels,
records or differing timing, then the result
of the operation will be a buffer with the
smaller values of these. (i.e. if A has 8
records and B has 6, then the result will
have 6 records.)
Note: At this point these operations don't
check the gains of the data, make sure your
data is all at the same gain

data with a user-specified -3db cutoff freq.
This uses the algorithm from "Single Channel
Recording" ed. B. Sakmann & E. Neher, Chap 11.
  The moving average algorithm successively
takes the local average of a number of data
points around some central data point and then
replaces the central data point with the average.
  The FFT algorithm, performs a FFT on the
data, and then low pass filters it and then
reverse FFTs it.  This uses an algorithm from
Numerical Recipes in C.
eoh

hs:3:1:Gaussian Filter

------------------- Series Resistance ------------------
hs:1:8:Series Resistance
boh
  This item allows you to measure the
Series Resistance from data.  The series
resistance is measured by calculating
the height of a voltage-clamp transient.
Data should be leak-subtracted first.
  Note that this method is not the best
method to calculate Rs, and will give an
underestimate.  The series resistance is
calculated by measuring the height of the
capacitive transient and dividing the
voltage by the measured current (R = I/V).

------------------- Display ------------------
hs:1:5:Display Options
boh
  This allows the user to control aspects
of how data is displayed on the screen.
eoh

hs:2:1:Show all pts in record
boh
  Selecting this toggles this option.
  If this is enabled then Tack will
display all of the data points for a
given record (within the selected timing
range of course) on the screen.  That
is, if there are more data points in a
record than there are pixels on the
screen horizontally then Tack will
show multiple Y points for each X point.
  If this is disabled then Tack will
only display one Y point for each X
point.  Disabling this feature causes
the display to draw faster.
eoh

hs:2:2:Connect the points
boh
  Selecting this toggles this option.
  If this item is enabled then Tack
will connect the data points on the
screen with lines.  This causes the
display of data to look nicer, but
significantly slows the display
of data.
eoh

hs:2:3:Grid and Axes
boh
  This option allows the user to configure
how the grid and axes in the data window
are displayed.
eoh

hs:3:1:X Axis
boh
  This item allows the user to determine
where X axes are to be placed in the data
window(s).  The user can select a variety
of X axis configurations varying from no
X axis to three, appearing at the top,
middle and bottom of each window.
eoh

hs:3:2:Y Axis
boh
  This item allows the user to determine
where Y axes are to be placed in the data
window(s).  The user can select a variety
of Y axis configurations varying from no
Y axis to three, appearing at the left,
middle and right of each window.
eoh

hs:3:3:Grid
boh
  This item allows the user to determine
the display of the grid in the data
window(s).  The grid can be horizontal,
vertical, both horizontal & vertical or
neither.  The spacing of the grid is
determined by the number of divisions
(see next item).
eoh

hs:3:4:Divisions
boh
  This item allows the user to set the
number of divisions for both the X and
Y axes.  The number of divisions
determines where the ticks are placed
on the X and Y axes and the spacing of
the grid.
eoh

hs:3:5:Line Style
boh
  This item allows the user to set the
line style for the grid.  The line style
is specified by a hexadecimal number
(0 -> FFFF) which specifies how the line
is displayed.  FFFF corresponds to a
solid line, while 0 corresponds to no
line.  A value of  0F0F would make a
dashed line, while 1 would make a faintly
dotted line.  There are 65536 possible
configurations - why not try them all?
eoh

hs:3:6:Okay
boh
  Selecting this causes any changes that
you have made to the grid and axes to go
into effect.
eoh

hs:3:7:Cancel
boh
  Selecting this causes any changes that
you have made to the grid and axes to be
discarded.
eoh

------------------- Other Options ------------------
hs:1:6:Other Options
boh
  This allows you to configure several
aspects of Tack's operation.
eoh

hs:2:1:XMS
boh
  Selecting this toggles this option.
  When this feature is enabled, Tack will
use memory accessed via the XMS specification
in order to store data buffers.  XMS memory
is memory above the 1 MB boundary on PC-AT
class computers (80286 and above class
microprocessors).  This memory can only be
accessed if you have installed the XMS driver
HIMEM.SYS (supplied free of charge by
Microsoft), or a compatible XMS driver (e.g.
Desqview's QEMM memory manager) in your
CONFIG.SYS config.sys file.
  The use of XMS allows Tack to store data
above the conventional memory area, which allows
more room for Tack to work.  This feature
need not be disabled unless you suspect a
problem or else have other needs.
eoh

hs:2:2:Sounds
boh
  Selecting this toggles the state of
whether Tack will generate sounds.
When disabled Tack will make no noise.
eoh

hs:2:3:Okay
boh
  Selecting this causes any changes
that you have made to the options
on this menu to be saved.
eoh

hs:2:4:Cancel
boh
  Selecting this causes any changes
that you have made to the options
on this menu to be discarded.
eoh

------------------- Write Config File ------------------
hs:1:7:Write Config File
boh
  When this option is selected the current
configuration data will be written to the
Tack.cfg configuration file.  Only the
items that are on controlled by config menu
are stored in this file.  These are:
- Graphics display adapter & resolution
- Colors
- Font
- Printer
- Sounds
- Display Settings (Show All Pts, Connect
    the Pts, Grid)
- XMS Usage
