Hi @whinds , any head way on this issue? I am running into this problem as well.

No complete solution yet I'm afraid. One trick that helped was to "use mri_convert -c" on the T2 prior to processing, which padded the volume with zeros making transformations and resizing safer.

mri_convert -c -odt float -rt cubic $T2 $T2

Also, in one instance, one of the surface reconstructions failed on a virtual machine was instead able to succeed using the docker method.

My data is 1.0 mm resolution and prone to movement artifacts, so it could also be an underlying issue.

Understood. Thanks for response @whinds. I will give that a try.

@whinds Thanks, that seems to have done the trick on some of the images that failed on the first try.

Hi, sorry for the late reply, but if the resample/cropped t2w-image.nii.gz seems to not cover the full brain region, I would expect this to be an issue with the brain extraction mask. All the above command does is to sample the original (bias corrected) T2w image at the voxels of the supplied brain extraction mask, which is expected to match this image in native space.
