Hello,

I'm running Freesurfer 8.0.0 on a Rocky machine and run into an error when I use the -nonuintensitycor flag.  The same image finels run perfectly fine without that flag, but with the flag I get this error:

#@# Intensity Normalization Tue Mar 18 15:22:23 EDT 2025

/s3l/fs_subjects/RAD_2100A/mri

 mri_normalize -g 1 -seed 1234 -mprage nu.mgz T1.mgz

using max gradient = 1.000

setting seed for random number genererator to 1234

assuming input volume is MGH (Van der Kouwe) MP-RAGE

reading mri_src from nu.mgz...

error: mghRead(/s3l/fs_subjects/RAD_2100A/mri/nu.mgz, -1): could not open file^@

error: mri_normalize: could not open source file nu.mgz^@

Command exited with non-zero status 255

This looks to be a bug - any ideas for a workaround?  Thanks!
