- How would you like to be able to customize
- MacFormula with your own values or symbols? Well, you
- now have the capability to do exactly that. Choosing
- the AddSymbols command from under the Special menu
- brings up a modal dialog which allows you to add, delete,
- and change the parameters in the symbol table. The values
- that are currently stored are very accurate, especially
- the “Exact Mass” values. I know this is true, because I
- used these values to calculate High Resolution Mass Spec
- values for the compounds in my dissertation, and they came
- out right on the money. However, if you want to change
- them that’s entirely up to you.
- IF YOU MAKE CHANGES TO THE SYMBOL TABLE, PLEASE
- DO NOT DISTRIBUTE YOUR MODIFIED VERSION OF
- MACFORMULA
- To make changes:
- First of all, although it is not hilited, the “Add”
- button is the default button, hitting <CR> or <ENTER>
- is the same as clicking this button with the mouse.
- To add a symbol, type in either an UPPERCASE
- one-character symbol, or a two-character symbol with
- the first letter UPPERCASE and the second letter
- lowercase. It is very important that this protocol
- is followed exactly. Also, you must choose a symbol
- that is not currently being used, if you do not then
- MacFormula will let you know. After choosing your
- symbol, enter in a value for the average mass and the
- exact mass. These values may not be greater than 10
- characters (including the decimal point). If you want
- to change an existing symbol, delete it first and then
- re-add it with the new values. If you are not sure if
- a symbol already exists, enter the symbol and hit the
- “Find” button. After you have made all of your changes,
- press the “Save Changes” button to make them permanent.
- Hitting the “Cancel” button anytime before hitting the
- “Save Changes” button will discard all of the changes
- (or mistakes) you have made up to that point.
- I have already entered values for 'Ph', 'Me', and
- 'Bu.' I can't remember if I put anymore in there. Use
- MacFormula to calculate values for your new symbols
- and write them down on paper before entering the
- “AddSymbols” mode.
