Running TORTOISE Modules

With distributed IDL VM:

For DIFF_CALC:

Go to DIFF_CALC/diffcalc_main
Type calcvm

For DIFF_PREP:

Go to DIFF_PREP/diffprep_main
Type prepvm

With IDL VM installed separately (we highly recommend using the above option, as this method has resulted in some errors reported by users):

For DIFF_CALC:

Go to DIFF_CALC/diffcalc_main
Type idl -vm
Select diffcalc

For DIFF_PREP:

Go to DIFF_PREP/diffprep_main
Type idl -vm
Select diffprep_gui

With IDL license:

For DIFF_CALC:

Go to DIFF_CALC/diffcalc_main
Type idl -vm
Type diffcalc

For DIFF_PREP:

Go to DIFF_PREP/diffprep_main
Type idl -vm
Type diffprep_gui for GUI version

Command line version exists, and is described in the From Command Line section.

An important note: if you are running the software on a Mac, be sure to use the 32 bit IDL VM. This can be done from the command line by typing idl -vm -32

If you get the message "command not found", try running ./calcvm or ./prepvm to start the IDL VM versions of the software
