Hi Daria
We had the same problem on Macs, although they had enough memory. A work
around would be to reduce the number of training subjects in the trctrain
folder. When we used 26 instead of 33 training subjects, the error
disappeared.

FYI: In the -prep and -path sections I can run a 77 direction DWI on 33
training subjects with 8Gb RAM, Ubuntu 12.04 but it spills over into the
swap memory. The -bedp section is not a memory hog at all.

I cannot comment on 5.1 vs waiting for 5.3.
About the single time point. The reason is not that we need the base. We just
want to make sure that that image undergoes the same processing steps as all
other images to avoid a processing bias.

Hello Freesurfers,
I would like to use mri_cor2label for areas of the cortext defined in
the FreeSurferColorLUT.txt. There are many ROIs whose IDs are 255,

Hi Anastasia,
Thank you for your response. I think I figured out what was the problem: The
delimiter for the 3 column .bvec file MUST be SPACE/TAB, otherwise the program
fails to reshape it correctly. In my case the delimiter was , and the program

Hi, yes, this release should fix the glibc problem on fedora 18 and
hopefully unbuntu 13 as well. If you have a chance to exercise all of it
(run recon-all on a subject, and run the guis like tkmedit, tksurfer,
