Re: [Freesurfer] Scripting: Feeding arguments and variables to script?

Hi Graham,

Kevin can answer the ones I can't, but I usually use env variables and the tcl $env(ENV_NAME) to get at them. The following variables are define by tksurfer:

$subject $home $hemi

among a bunch of others.

Folks:

Basic scripting questions:

1. When you launch FS from command line and provide a -tcl command to invoke

a tcl script, how do you supply arguments to that script (or is that even possible)?

FWIW, I tried things along the lines of:

set myvar [lindex $argv 1]

... and this gives an error about "no such variable".

2. Once a script is running, what variables can it look at to find out:

Current subject id Path to current subject Details about currently loaded surfaces: especially right or left

3. What assumptions, if any, can a script rely on as to current directory?

Thanks,

Graham
