- autoseq (version 94.05.03) help
- -------------------------------
- autoseq extracts a variety of information from SCF and ABI files and
- writes these components to files. It acts as an interface to CTrace,
- CTraceFile, & CPeakList to perform a operations on the data, and the
- results of these operations are also directed to files.
-
- command line structure:
- % autoseq {flag_list} {filename}
- flag_list ::= {'-'} {flag} {flag_list}
- flag ::= 1 of the following:
- b [A,C,G,T]0+
- Specifies to which bases individual actions should be performed.
- More than one base may be specified. The default is -bACGT (all bases).
- bl [short bl=<trace minimum>]
- Set the baseline of the selected traces to bl. If bl is omitted then each
- trace is translated downward by the the minimum value for that trace.
- bpd [+integer maxnbhd=2]
- For every subsequence of length nbhd (1<=nbhd<=maxnbhd) in the predicted
- sequence, write the index of the 3' most peak center for that subsequence,
- the delta for the subsequence, and the subsequence itself. The delta
- between bases m and n is defined to be the distance between the centers of
- the peaks corresponding to bases m and n.
- bp Output the base-to-trace-position mapping stored in file [prefix.bp]
- d1 Compute 1st derivative trace [prefix.#.d1]
- d2 Compute 2nd derivative trace [prefix.#.d2]
- fmt [{ABI0,ABI1,ABI,SCF} fmt=<best guess>]
- Read in specified format; guess if not specified.
- ABI0 - ABI (raw data)
- ABI1 - ABI (2nd trace set)
- ABI - ABI (processed data)
- SCF - Standard Chromatogram Format
- fs Write the sequence predicted stored in the file. [prefix.fseq]
- ft Writes the trace of expected fluorescence from the list of selected peaks.
- Expected fluorescence is calculated by fitting a Gaussian at the peak
- center using the peak height & width; see fw. [prefix.#.ft]
- fw [+short fw=50]
- Specifies the breadth of the Gaussian used to model the fluorescence of
- each peak (ie. Gaussian limits are [peakcenter - fw , peakcenter + fw]).
- h Include descriptive headers in output files
- help This help display
- i Write the individual traces after translation (bl), scaling (s),
- smoothing (sm), and transformation (x). [prefix.#]
- l [+int index]|'p'
- Specifies the left cutoff index. Peak positions are reported relative
- to the left cutoff. If 'p' is passed as the argument, the left cutoff
- is set to the primer position.
- o [string prefix=<input filename>]
- Specifies file prefixes for output filenames. If the prefix is a file,
- suffixes will be added as appropriate. If the prefix is a directory (that
- is, ends in a '/'), files will be redirected to that directory and
- the input filename will be used as the filename prefix. The hash symbol
- ('#') may be used a placeholder for the base identifier; if it is omitted,
- .# will be appended to the prefix specified with this flag.
- pmc [+double PMC=1]
- Specifies the minimum peak height as a product of the mean and the
- Peak Mean Coefficient (PMC). For instance, if the mean trace value
- is 20, then -a 1.5 will only pick peaks above 24 =(1.2 * 20).
- p [+int separation=4]
- Prunes peaks by doing a pairwise comparison of adjacent peaks and
- discarding the less-probably peak of each pair which is separated by less
- than separation. If os is specified, a list of pairwise comparisons which
- resulted in the removal of a peak is output. [prefix.pruned]
- ps Write the predicted sequence (the sequence chosen by CPeakList)
- pt Generates traces which represent peaks and their widths & heights.
- Peak traces are especially informative when overlaid with the
- individual (i) trace. [prefix.#.pt]
- q Quiet mode. Only errors will be displayed.
- r [int index]
- Specifies the right cutoff index. If index is <0, the right cutoff
- will be set to +index from the end of the trace. See l.
- rt Output the residual trace computed by subtracting the expected fluorescence
- trace from the observed data [prefix.#.rt]
- s [string filename]
- Scale traces using scales from filename (in ACGT order), or default scales
- if not specified.
- sm [short iterations=2]
- Smooths by using a weighted average of the 3 points about a particular
- index, with the special case of the endpoints handled by throwing out the
- third point and normalizing the weighting coefficients. The process is
- repeated iterations times.
- tfs Output a summary of tracefile statistics and peaks [prefix.tfs]
- ts Output a summary of individual trace statistics and peaks [prefix.#.ts]
- version Print version info
- v (extremely) Verbose mode
- x [string filename]
- Applies a 4x4 transformation/orthogonalization matrix to the 4 traces,
- producing a new set of traces which replaces the existing set.
- Transformation matrics are expected to be 4x4 matrix of the form:
- (file consists of mTS values only)
- M = [,A] [,C] [,G] [,T]
- [A,] mAA mAC mAG mAT
- [C,] mCA mCC mCG mCT
- [G,] mGA mGC mGG mGT
- [T,] mTA mTC mTG mTT
- The general equation for the resulting traces is:
- R = M O <==> R(T,i) = sum [ mTS x O(S,i) ]
- S in {ACGT}
- where R is the resulting vector of 4 traces
- O is the original vector of 4 traces
- M is the 4x4 ({ACGT}x{ACGT}) matrix whose elements m(i,j) are
- the cross-term contributions of channel j to channel i
- S & T are trace identifiers (Source & Target) in {A,C,G,T}
- i loops over the indices of the trace
- z [+double threshold=0]
- Specifies the epsilon about zero in which derivatives are considered to
- be exactly zero, and thus the crest (trough) of a local maxima (minima).
-
- Argument specifications are given in square brackets ('[' & ']') with their
- associated flags where applicable. Usually exactly one argument is
- expected; 0+ means that zero or more arguments may follow; 0,1 indicates
- 0 or 1 arguments are expected (ie. it's optional). If a flag has an
- optional argument which is omitted by the user, the following flag must
- begin with a hyphen ('-'); otherwise, the hyphen is optional. Default
- values are designated in the argument specification by an equal sign ('=').
- If any operation (ie. a flag that results in an output file) is specified,
- then none of the default operations are performed unless specifically
- requested. If a flag causes an output file to be written, the default
- filename for that file is indicated in square brackets. Generally,
- filnames are generated by appending a suffix to the input filename and are
- written to the same directory as the input file; the user may specify an
- alternate prefix or destination directory with the -o flag. The hash
- symbol ('#') is a placeholder for the base letter when the output file
- writes base-specific information; # may be used on the command line. If
- filename ends with '.s1' the suffix is removed. Peaks will be picked
- only if necessary for the requested operations.
- WARNING: If file with an output filename already exists, it will be
- overwritten.
