Have you looked at the modifications for the BIDS App version: https://github.com/BIDS-Apps/freesurfer I believe the latest image (using FS6) is only 6.37GB and you could bypass the run.py script with --entrypoint bash to run your typical recon-all commands -Alex -

[Freesurfer] autorecon2-cp vs autorecon2-wm

2017-01-25 Thread Alex Cohen
Just out of curiosity, digging through recon-all finds this section quoted below, however I thought -cp and -wm started at different spots?: case "-autorecon2-cp": case "-autorecon2-noaseg": case "-autorecon2-wm": set DoNormalization2 = 1; set DoSegmentation = 1; se
