Feng-Xian,

It appears that you do not have permission on your system to change the limits. So you will have to edit the scripts make_average_volume, make_average_surface and make_average_subject to comment out the 'limit' line, so that it looks like this:

#limit descriptors unlimited

Hi,

I have a problem with make_average_subject.

After running all commands (including ln -s $FREESURFER_HOME/subjects/fsaverage and recon-all -s <subjid> -qcache for all my subjects) about running QDEC, I found that QDEC could not analysis my group.

Because the group have 1 factor and three levels, QDEC can't run.

So, I want to change the method of analysis from QDEC to DODS.

I had a fsaverage file when I running QDEC, but the fsaverage did not use my subjects to make.

So, can I use the fsaverage file to run DODS?

If not, I should make a new fsaverage with my subjects.

But, I encounter the problem about make_average_subject.

When I type:

make_average_subject --subects <subjid1> <subjid2> ...

the terminal show that:

limit: descriptors: Can't remove limit

What's wrong about the command I type? And, how to solve the problem?

Thank you in advance!

You don't *have to* to run make_average_subject to do your analysis, only if you want to view the results on a map with the curvature patterns averaged over your subjects. As for the limit error, how old is your version of freesurfer? That line was removed about 1.5 years ago...
