Many thanks for your e-mail.

Yes, I've noticed that. But I made sure the SUBJECTS_DIR is the right one. Everything else is running without problems. And if I type cd $SUBJECTS_DIR, it goes to the right folder, which is not that folder on /tmp/qdec_project_archive.

Your SUBJECTS_DIR is set to /tmp/qdec_project_archive, which is probably wrong.

Dear all,

I'm using Qdec and wanted to map an ROI to all participants in the study, but I always get an error. I've used FS 4.0.2 for recon-all for all subects. Now I'm running stats with FS 4.1.0 (I did 'recon-all -qcache -subjid <sub>' for each person using version 4.1.0). I'm using Debian.the qdec

I've saved the ROI to the SUBJECTS_DIR folder.

The error I get is:

mri_label2label --srclabel rh.mtg1 --srcsubject fsaverage --trgsubject C01_CY --trglabel rh.mtg1 --regmethod surface --hemi rh

srclabel = rh.mtg1 srcsubject = fsaverage trgsubject = C01_CY trglabel = rh.mtg1 regmethod = surface

srchemi = rh trghemi = rh trgsurface = white srcsurfreg = sphere.reg trgsurfreg = sphere.reg usehash = 1 Use ProjAbs = 0, 0 Use ProjFrac = 0, 0

Many thanks for your help.

Thanks for your help. I've realized that, when I save the project, and open them again, the SUBJECTS_DIR changes, but only for Qdec. But now it's running ok. Thank you.

You can try

unsetenv SUBJECTS_DIR /tmp/qdec_project_archive

and set the SUBJECTS_DIR to the right directory again.

There are two places where it might influence it: 1. Computation of the FWHM used for corrections for multiple comparisons depends on the average total surface area of the group. These are probably pretty similar across groups. 2. The size of a cluster is computed (roughly) based on the average area of that cluster across the subjects in the group. This probably is only a factor on small clusters or clusters with a "funny" shape (ie, a large perimeter to area ratio, eg, long and thin).

Hello, I need to know if the average subject can influenciate the final statistics. Can I have an average subject from two groups an use it to comparate another diferent group? Thanks, Kelly
