External Email - Use Caution        

Hello Freesurfer developers,

I'm currently attempting to run recon-all -s sub-GE101 -localGI, but I continue to get this error:

{ Error using make_outer_surface (line 57)
mri_mc failed: changing type of input volume to 8 bits/voxel...

ASSERTION FAILED:
/home/rd521/space_freesurfer/build/docker_ubuntu22/trunk/rd521-7.4.1/utils/mrisurf_metricProperties.cpp:4249
mris->dist_nsize == 0

>>ERROR: make_outer_surface did not create output file 

I have not seen any email threads with a similar error on this version, and I'm unsure how to approach this issue.
