The GPU stuff may or may not work. It was hard to maintain because the GPUs kept changing so much, and it would not surprise me that the code from 5.3 is incompatable with GPUs today. But it looks like the error is that it could not find a file. Does that file actually exist?

Hi!

I am trying to run recon-all in version 5.3 with the -use-gpu flag. I am getting a strange error that I would love to get your input on:  cannot find freesurfer/average/RB_all_2008-03-26.gca 

Neither the file nor the path exist. 

This is the entire input and output:

recon-all -s hum_14600_parallel -i /neuro_tools/freesurfer/subjects/hum_14600/mri/011/mp2rage.nii -all -use-gpu

Is there some documentation on how to set up the environment beyond LD_LIBRARY_PATH? Could that be the issue? Everything works fine without the -use-gpu flag.

Thank you! Caspar
