I am running surfaced based analysis using ROI approach. My mris_preproc, mri_surf2surf and mri_glmfit worked as expected. Since i restricted the region i built my own monte carlo "mri_mcsim --o roianalysis/average/mult-comp-cor/fsaverage/rh/rightmaskforcomp --base mc-z --surface fsaverage rh --nreps 10000 --label 2mask" which worked. However, when I wanted to run the mri_glmfit-sim using this command line " mri-glmfit-sim --glmdir rh.score.glmdir --cache-dir roianalysis/average/mult-comp-cor --cache-label rightmaskforcomp --cache 2 pos --cwpvalthresh 0.05 --2spaces" i got an error

I looked into roianalysis/........./fwhm17/pos/th20/mc.z.csd and it does exist. 

I saw a post like this on the forum but it wasn't answered. How can I direct it to my simulation on my subjectfolder (i.e., desktop/roianalysis/......)? Thanks
