It is looking for the aparc+aseg.mgz so it can report the segmentation that each cluster is in. If you don't need this information, then run this command:
mri_volcluster --in GroupAnalysis_abs.glmdir/contrast/sig.mgh --mask GroupAnalysis_abs.glmdir/mask.mgh --reg /usr/local/freesurfer/subjects/fsaverage/mri.2mm/reg.2mm.dat --no-fixmni --cwsig GroupAnalysis_abs.glmdir/contrast/permcsd.sig.cluster.mgh --sum GroupAnalysis_abs.glmdir/contrast/permcsd.sig.cluster.summary --ocn GroupAnalysis_abs.glmdir/contrast/permcsd.sig.ocn.mgh --cwpvalthresh .05 --csdpdf GroupAnalysis_abs.glmdir/contrast/permcsd.pdf.dat --csd GroupAnalysis_abs.glmdir/csd/permcsd.j001-contrast.csd --vwsig GroupAnalysis_abs.glmdir/contrast/permcsd.sig.voxel.mgh
I got this command out of your log file and removed the "--seg" part.

Dear all,
I was running the simulation:
mri_glmfit-sim \ --glmdir GroupAnalysis_abs.glmdir \ --sim perm 1000 3 permcsd \ --sim-sign abs \ --cwpvalthresh .05
and unfortunately I got the following error: mri_volcluster --in GroupAnalysis_pos.glmdir/contrast/sig.mgh --mask GroupAnalysis_pos.glmdir/mask.mgh --reg /usr/local/freesurfer/subjects/fsaverage/mri.2mm/reg.2mm.dat --no-fixmni --cwsig GroupAnalysis_pos.glmdir/contrast/permcsd.sig.cluster.mgh --sum GroupAnalysis_pos.glmdir/contrast/permcsd.sig.cluster.summary --ocn GroupAnalysis_pos.glmdir/contrast/permcsd.sig.ocn.mgh --cwpvalthresh .05 --seg fsaverage aparc+aseg.mgz --csdpdf GroupAnalysis_pos.glmdir/contrast/permcsd.pdf.dat --csd GroupAnalysis_pos.glmdir/csd/permcsd.j001-contrast.csd --vwsig GroupAnalysis_pos.glmdir/contrast/permcsd.sig.voxel.mgh

Seems that the simulation was completed saying that mri_glmfit simulation done but I did not get any clusters or any file permcsd.sig.cluster.summary.
Also I am not sure if I need to use the while running the mri_volcluster the fsaverage or I should use the cvs_avg35 since my FA data was registered over the CVS space.
Can I just do something further to catch my corrected clusters? I attached my log file.
Thank you very much. Antonella
