I encountered an error while running recon-all where T1.mgz files for two subjects appear to be cropped posteriorly along the Y dimension (RAS). The cortex is preserved, but portions of the skull and the scalp are removed. The input file ($subj/mri/orig/001.mgz) is intact, suggesting a possible issue during conversion (e.g., mri_convert).

I didn’t find similar reports in the archive, and the problem reproduces identically across both versions of FreeSurfer below. recon-all.log files are attached. 

Any insight would be greatly appreciated. Thank you!
