I am working through the FreeSurfer tutorial on cannabis using Ubuntu VM on windows (FS version 7.1.1). I am on the group analysis portion of the tutorial attempting to run mris_preproc. However, I am receiving the following error upon running the script:

error: No such file or directory
error: mghRead(/home/developer/FreeSurfer/osg-outputs/cannabis-BL/sub-101/surf/rh.thickness.fwhm10.fsaverage.mgh, -1): read error

I wonder if something has been going wrong with recon-all as I believe it is saying that there is an error with one of the outputs in sub-101? Recon-all has been running in a suspiciously short time (~5 hours), but I do not know enough about the processing steps to know what might be occurring wrong in recon-all or in trying to run mris_preproc.

Please let me know if I can send you anything else to provide more information on the issue.

Thank you for your time and assistance.

Best wishes,

Joanna
