Re: [Freesurfer] Scalable recon workflow

There's a small percentage of subjects that need more than the 8Gb of memory (for mris_fix_topology if my memory is correct). You could increase the memory allocation for all subjects, or you could run your entire dataset with 8Gb per subject, then re-run the ones that failed with increased

Hi Paul, Thanks for your speedy response! In that case, I assume 1GB/core is the memory allocation? Is it helpful to increase that? Best, Mitch From: freesurfer-boun...@nmr.mgh.harvard.edu on behalf of Paul Wighton Sent: Tuesday, May 3, 2022 1:34 PM To:

Hi Experts, If I have 100s of subjects to recon and have access to an HPC with both GPU and CPU options what is the recommended flags to maximize speed performance? Is … -parallel -openmp 4 … still the best approach? And if so, is 2GB memory/core best (keeping it 8GB memory/subject) or is

Dear Asa, Thank you very much for the interest in our thalamic atlas. The atlas is defined as a tetrahedral mesh (not voxels) in its own average space. So there is no probabilistic map in MNI space. You could try segmenting your MNI template with FreeSurfer + the thalamic module and use that.
