External Email - Use Caution

Dear FreeSurfer Developers,

I'm attempting to open Qdec on my linux server. I used to open it with freesurfer 6.0.0 activated to analyze our local gyrification index data. That version is not available anymore in our service; hence, the Freesurfer version I can use is 7.1.0 and when I tried to open Qdec the following message appears: Can't find a usable init.tcl

We tried to contact our IT sever to see if there was a way we could use our old Freesurfer version 6.0.0 (which we used to calculate the LGI). But they replied to us with the following:

"A G6 compute server must be used for freesurfer 6.0.0. The background is that the TCL 8.4.6 used by Freesurfer is very old (from 2008) and is no longer supported by current operating systems. The same applies to the latest version 7.2.0. We have TCL 8.6.11 available."

Is there anyway we can install Qdec for this new version of freesurfer 7.1.0? so we are able to continue with the analysis.

I am open to any other possible solutions.

Kind regards,

Rosa
