When running tksurfer in 7.1.1 (from https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.1.1/freesurfer-linux-centos7_x86_64-7.1.1.tar.gz ) , I get:

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"
Tix_Init failed: Can't find a usable Tix Init.tcl in the following directories:
./library
./tix8.1
./library
./tix8.1
/usr/pubsw/packages/tcltktixblt/current/lib/tix8.1

This probably means that Tix wasn't installed properly.



What should I do about this?

It works under 6.0.1.
