hello!

after freesurfer segmentation (through fmriprep v23), i converted the aparc+aseg.mgz file into a nifty file using the below code (freesurfer v7.4.1):
-rl $fs_dir/mri/rawavg.mgz
-rt nearest $fs_dir/mri/aparc+aseg.mgz
$sub_dir/rois/anatomical/aparc_aseg2mprage.nii.gz

however, the voxel values of the aparc_aseg2mprage.nii.gz range between 31000-32000 and -31000- -32000. consequently, the label values for particular regions no longer correspond to what’s in the freesurfer manuals (like those listed here: FsTutorial/AnatomicalROI/FreeSurferColorLUT - Free Surfer Wiki).

would be incredibly grateful if i could be pointed to what i’m missing or what could be going wrong! thank you!
