Dear FS experts
I run a longitudinal analysis, and all steps (cross, base, long) were run without errors. I used QA tools in order to look at the results and all recons are fine.
However, when running glmfit with the --osgm option there is no error message, but there is also no results (sig=0, F=0). In the log I realized that the mask is empty (see below).
Found 149955 points in label. Pruning voxels by thr: 0.000000 Found 0 voxels in mask Saving mask to Cap_Thickness_LH.glmdir/mask.mgh Reshaping mriglm->mask... search space = 0.000000
What are the most plausible reasons for this empty mask? Should I try the pruning option?
Thanks in advance Regards Jürgen
