[Freesurfer] Qdec taking a very long time

Hi FreeSurfers

I am quite new to freesurfer. I am trying to run a GLM analysis on some FreeSurfer data.

I am analysing volume (surface based) with a smoothing of 5mm, using one discrete factor and one covriate on 252 subjects.

I started the analysis on Friday 4th October. Its now been 8 days and the process is still running. The terminal is spitting out long columns of numbers so it looks like it is running, but I am supprised that it takes this long. Doing similar analysis in FSL and SPM takes a few minutes to about an hour. I am assuming therefore that something has gone wrong.

If anyone can help me get to the bottom of this that woudl be very helpful.

Many thanks

Mark
