Dear experts, Thanks in advance for any help you can provide. I’m using “mri_coreg” and trying to accelerate it with the “--threads” (and/or “--nthreads”) flags. However in the subsequent command feedback it looks like it is still using just one thread (see output below, “nthreads 1”; and also it is no faster). Am I doing something obviously wrong? There are no errors and it executes successfully… Not sure if relevant but I’m using this for nifty (.nii.gz) files, my command is: “mri_coreg --ref <path/to/ref.nii.gz> --mov <path/to/mov.nii.gz> --reg <path/to/registration.lta> --threads 10”
I’m on MacOS running a recent dev download (freesurfer-macOS-darwin_arm64-dev-20241011), but I’ve tried it on 7.4.1 with no success either.
