This is what the output looks like when I execute the bash script:

When I checked the folder, I saw only the parcellation results. Neither the moved floating image nor the forward field were generated.

I initially thought this might be a memory problem and I set --thread 1 but I ended up getting the same result (Killed).

I've searched the list and there was another error (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg75001.html) similar to mine. But I don't think mine was related. Can anyone provide any insight into this?
