No, not any more. We used to have it, but it was too hard to maintain.
You can always run in parallel on the CPU (-threads N)

You have a space in your current path (between severe and similar). That
is causing the problem

I am currently running FreeSurfer 7.4. I wrote a script using the
program mri_volsynth. I noticed for the first time the program was
trying to write files where it did not have write permissions. It

what do you mean "extract" the cluster? Do you want mean thickness for
each cluster? Or the mean contrast? Of all the voxels in a cluster? For
the first two, you can use something like
mri_segstats --seg clusterseg.mgz --i contrast.mgz --sum summary.txt

Is that an MP2RAGE? The background may be messing things up. You can try
masking it, eg,
mri_synthstrip --i yourimage.mgz --o stripped.mgz
Then pass stripped.mgz to recon-all

Dear FreeSurfer Experts,
Sorry, I think I've found the answer. It's because Jacobian correction
was performed for mris_preproc, right?

When working with area, you need to turn on jacobian correction.
mris_preproc will do this automatically, but you have to add --jac to
mri_surf2surf explicitly

Dear FreeSurfer Experts,

tried the -expert
options file that you suggested anyway, but it exited with errors
unfortunately and didn’t work. Is there anything else we can try?
Thanks again for your help!

you cannot apply kinetic modeling to one frame. W

Hello,
So I ran FreeSurfer to get numeric data from MRI images and got these
files under the stats page.
Screenshot 2024-03-18 144107.png
occurs on:
fcseed-sess -s ID -cfg wm.config -overwrite
ERROR: could not determine file for rs-fMRI_AROMA/ID/rest/001/fmcpr

Hi Stefano, I think I found and fixed the problem. Can you try these?

you cannot apply kinetic modeling to one frame. What is you ligand? For
a one frame acquisition, you usually use an SUV analysis.

Hi experts,
As stated in the subject, can kinetic modeling be applied to PET data
Thank you very much!
