I am working on measuring cortical thickness of a patient group. I am using Ubuntu 14.04

Somehow, if I use command line to perform the analysis, Freesurfer/qdec is working fine but if I use Qdec interface, it works fine initially but when I switch to display window, it doesn't allow me to change/edit FDR p-values, threshold min and max, although I can click on all the options on display window e.g. inflated, pial, white, etc.

Also, when I tried to do the same on other computer (Mac), it works fine for me.

I was wondering if this is because of video card problem or something. The thing is it was working before for some time, then after a computer crash, it no longer works. We replaced the video card but are still experiencing the same problem.

At this point I would welcome any suggestions.

Thanks,

Sahil
