No, more like running the voxelwise comparisons only on voxels that have positive BP between 2 group. Is that possible?
On another note, I am running into a puzzling "Segmentation fault" error with the following command:
mri_glmfit-sim --glmdir lh_ad_hc.glmdir --cache 2 neg --cwp 0.05 --2spaces

Reading annotation /Users/MacPro/Documents/NIMROD_DTI//fsaverage/label/lh.aparc.annot
reading colortable from annotation file...
colortable with 36 entries read (originally /autofs/space/terrier_001/users/nicks/freesurfer/average/colortable_desikan_killiany.txt)
Segmentation fault ================================================
Strangely, I can't seem to reproduce this error consistently too. Sometimes, after a pause of few minutes, the exact same command works! This happens on smoothed and non-smooth PET data.
I have attached the text outputs resulting from both scenarios 1) seg_fault and 2) no_seg_fault (about 10 minutes between each execution).
The mri_glmfit-sim version is v .53.2.2 2015/08/28 19:00:13 I am running this on a Mac Pro with 64 GB RAM.
Thanks again

I'm still not sure what you mean by "positive BP between 2 group". Do you mean masking out voxels where either group is less than 0? This is not possible in mri_glmfit, but you could do it post hoc.

There is nothing obvious going wrong. If the exact same command sometimes fails and sometimes works, then it may be a problem on your system. In any event, without a reproducible error, I can't really debug it.
