External Email - Use Caution        

Dear all,

I tried to check the talairach transformation under Freesurfer 7 linux version (freesurfer-linux-centos6_x86_64-7.1.1-20200723-8b40551). However, neither command works as expected.

the command "freeview -v bert/mri/T1.mgz -v bert/mri/brainmask.mgz:reg=bert/mri/transforms/talairach.xfm" gives the following message in the terminal: "Not reading in xfm fileinfo". Both T1 and brainmask is loaded, but the transformation seems to be not applied.

the command "tkregisterfv --s bert --fstal --surf orig" works only without the flag --surf.

the command "tkregister2 --s bert --fstal" gives the following messages:

Tcl_Init failed: Can't find a usable init.tcl in the following directories:
    /usr/pubsw/packages/tcltktixblt/current/lib/tcl8.4
This probably means that Tcl wasn't installed properly.
Tk_Init failed: invalid command name "tcl_findLibrary"

The green border is not shown, only the target and movable images are visible.

Any idea how to fix this?

Best,

Gabor
