Hi Falk
the dev version of mri_ca_label does use openmp, so should be faster.
cheers

Hi Bruce,
I started the process again with openmp set to 12 using the dev build from 12th
July. However, mri_ca_label uses only 1 thread at that point. So I don't assume
any faster processing.
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
