Hello M.Yujing,

 

I’m using the HCP-A cohort (Human Connectome Project – Aging), where the structural MRIs were preprocessed. So, I’m working directly with the FreeSurfer outputs provided.

Is it possible that the lh.sphere.reg of this subject is corrupted?

 

Thank you,

 

Wassima

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

Hello M.Douglas,

 

I’m running the following command: mris_preproc --fsgd FSGD2.fsgd --target fsaverage --hemi lh --meas thickness --out lh.uci_nuci.thikness.00.mgh.

Please find attached the log file.

 

Thank you,

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

Hello FreeSurfer Developers,

 

I'm conducting the Surface Based Group Analysis explained on the tutoriel (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisV6.0)

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,
