Hi freesurfer folks, I am using mri_convert to reorient my custom cortical parcellation (a nifti file generated from an annotation file), and I have run into some unexpected blips with some seemingly errant reindexing. Here is the command I am using:
mri_convert -rl FREESURFER/mri/orig/001.mgz -rt nearest FREESURFER/label/ROIs_custom.nii.gz -nc reorient/ROIs_custom_reorient.nii.gz For the most part, this works well for most of the indices. The biggest problem is that the highest value index (2063) is being completely relabeled in ‘ROIs_custom_reorient.nii.gz’ with several smaller values in the 20’s range. But this occurs to a smaller extent with many of the other regions as well, where small parts of those regions are being relabeled with values anywhere from 1 to 20. Can anyone give me some insight as to what’s up with this and what I might be able to do to fix it? Thank you very much for any help. -David
