To whom it may concern,

How are you recently?

I am trying to follow the the ENIGMA Cortical QC protocol to check my external surface result after order "recon-all". The detail of scripts is attached bolow (here).  

I used "tksurfer" to get a series of 4 images (.tif) files for each subject. But I always met this type of error.

surfer: Error sending tcl command LblLst_UpdateInfo 33 "frontalpole" 32 1 100 0 100:
	invalid command name "LblLst_UpdateInfo"
surfer: Error sending tcl command LabelsChanged:
	invalid command name "LabelsChanged"

When I tried to solve this problem, I noticed that  the "freesurfer" was cannot support "tksurfer" any more. In stead, they suggested users to run another command 

"tksurferfv" , which will run freeview with most of the "tksurfer" command line options. But both of tksurferfv and freeview can not support "tcl" command. 

The error is written as below. Everytime I trid to run this script, I always found this error.

Option 'tcl' not recognized.

By the way, I wanna notify you that I am using freesurfer version 7.2.0 in CentOS 8.

How can I overcome this problem? Any advice would be appreciated!
Sincerely,
Yuhui
