Hard to say without the recon-all.log file, but my guess is that something is wrong with one of your surfaces. Load the surfaces in freeview and see how they look

Hi there,
Hope this finds you well

I have noticed the following error for some of my runs:

recon-all -s BT_055_base exited with ERRORS at Mon Dec 14 15:43:27 PST 2020

Here are details of the computer and FS version I am using:

OS: macOS Mojave (10.14.4)
FS: 7.1.1

It seems to happen at random, whenever I run recon-all on the same subject again, the error doesn’t occur. This is true for cross-sectional, base, and long processing steps in my machine. I have seen an email relating to this issue before, but I wasn’t able to access the attachment file which would fix the problem.

I was wondering if you guys would be able to help?

Thank you
