Re: [Freesurfer] make_average_subject with large cohorts

2010-06-07 Thread ythomas
I am a little out of the loop. Just to clarify, Marie is trying to create an average subject out of 400+ subjects that have been run through the freesurfer pipeline? I don't see a problem with that (except possibly memory issues). If the subjects are from a homogeneous population (whatever

Marie, The memory leak in mri_average has also been fixed. The new version is in the same ftp location as mris_make_average_surface. N. On Mon, 2010-06-07 at 14:43 -0400, Nick Schmansky wrote: > Marie, > > I fixed the memory leak that was causing your out-of-memory error when > running mris_ma

Marie, I fixed the memory leak that was causing your out-of-memory error when running mris_make_average_surface. A new mris_make_average_surface for Mac Intel Leopard is posted here: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/macos-leopard-intel/ I'm still looking into the mri_av

I am having a problem using tksurfer. It does not appear to be the same issue that others have had in the past with NVIDIA drivers etc. When I try to load a surface file the entire process freezes and eventually if I let it run, I will get the following error: gkl...@gklein-nspc:~$ tksurfer CL lh f

Hello freesurfers! After creating some labeling files from aparc.a2005s.annot, I noticed that my sulci and gyri volumes generated from the .label files (i.e., after running mri_annotation2label and mri_label2vol) were only representing the outer layer of the white surface. Is there any way to g

Dear FS experts, I have a anatomical scan of a subject with a rare neurogenetical disorder. I'd like to compare this with a age matched control group. How can I visualize a z-score transform map of the cortical thickness, i.e. how would I compute and vizualize the number/amount of standard devi
