Hello,

I am running the rebuild_gca_atlas.csh program and got the following error for seg_edited.mgz, which is the manually defined file imported from a different program outside of freesurfer.

mri_ca_train: segmentation file<path>/seg_edited.mgz is not type UCHAR or FLOAT

Is there a way to redefine the data structure?
