Hello,

I am installing Freesurfer with my limited coding knowledge and this problem with freeview came up when I was trying to view the volumes of recon-ed subject.

lab@lab-ThinkStation-E31:~/Desktop/freesurfer/subjects$ freeview -v practice/mri/T1/mgz
No command 'freeview' found, did you mean:
 Command 'treeview' from package 'treeview' (multiverse)
freeview: command not found

I checked and freeview is in the bin, and I even tried to install it according to its file by sourcing tcl_setup and others, but then this error comes up:

lab@lab-ThinkStation-E31:~/Desktop/freesurfer/bin$ source tcl_setup
bash: tcl_setup: line 47: syntax error near unexpected token `setenv'
bash: tcl_setup: line 47: `    if ( -e $TCLLIBPATH/tcl8.3 ) setenv TCL_LIBRARY $TCLLIBPATH/tcl8.3'

Can someone please give me any direction for how to solve this issue. I would appreciate the help very much.
(Freesurfer version 6 & Ubuntu 16.04)

Thank you all,
Idil
