Hi Graham, Another way is to generate your TCL on the fly, see below for a simple example:
- snip - #!/bin/sh outdir=/usr/people/johannes/scratch/fssubjects/pictures mkdir -p $outdir
cd $SUBJECTS_DIR # put your subjects here for f in CONTROL*; do for hemi in lh rh; do echo "scale_brain 1.05 redraw save_tiff ${outdir}/${f}_thickness_${hemi}.tiff exit" > /tmp/prettypic_$$.tcl tksurfer $f $hemi inflated -overlay $f/surf/${hemi}.thickness -tcl /tmp/prettypic_$$.tcl done done rm /tmp/prettypic_$$.tcl - snap -
Cheers, Johannes
