This is the error from log:

Reading source surface reg 
/media/sf_T1/freesurfer_results/HCA9679715_V1_MR/surf/lh.sphere.reg
error: Cannot allocate memory
error: TAGskip: tag=116798, failed to calloc 116799 bytes!

The TAG number looks wrong. I’m wondering how you created 
/media/sf_T1/freesurfer_results/HCA9679715_V1_MR/surf/lh.sphere.reg?

Best,

Yujing

That should be enough RAM. What is your command line? Can you send the log file?

but I keep getting the error: "Cannot allocate memory" while running the 
mris_preproc  command.

I'm using the data of 355 subjects stored on an external hard drive, and a pc 
of 23G RAM, but it stops at the 334 subject.
I've already tried with a windows and mac of 16G RAM and got the error, so 
moved to the other one but still getting the same issue.
Does anyone have any thoughts on how to trouble-shoot this? or any other 
alternative solution to run the mris_preproc on all the subjects?

FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0
Platforme: Debian 3.16.7


Thank you for your help,
