Re: [Freesurfer] mri_ca_label with high resolution data

Hi Bruce,

thanks for the quick reply. I'll try it out once I have a bit of memory available and let you know if it helped.

Best, Falk

Hi Falk

I think openmp will help with this in V6, but probably not before Bruce

Hi all,

I’m currently processing a 250 µm MPRAGE with a dev build from mid of May. Running recon-all with default parameters ran flawlessly. Afterwards I added the -hires flag to process the data without conformation. However, since Saturday morning it is kind of stuck at mri_ca_label stating:

saving sequentially combined intensity scales to aseg.auto_noCCseg.label_intensities.txt

while  consuming around 30 GB of memory. I ran something similar before and processing works, it’s just terribly slow. Maybe this particular stage is just not very efficient as it does take a few minutes on 1 mm data only? Would it help to add the openmp flag in that case?

Best,

Falk
