I’m wondering how you ran recon-all. Do you see the error even running it w/o any arguments?

Thanks Yujing,

Yes, I looked for the file permissions using ls -l. It does have execute permissions.

I also tried running chmod which didn't help.

Thanks,

After sourcing Freesurfer, $FREESURFER_HOME is added to the front of your $PATH.

1. ‘ls -l $FREESURFER_HOME/bin/recon-all’ to check if your recon-all has the execute permissions?

2. use ‘chmod +x $FREESURFER_HOME/bin/recon-all’ to grant the permission

Best,

Yujing

Dear group,

I'm trying to run Freesurfer on digitalOcean server running Ubuntu 22.10 (GNU/Linux 5.19.0-46-generic x86_64)

I Downloaded freesurfer 7.4.0 (freesurfer-linux-ubuntu22_x86_64-7.4.0-20230510-e558e6e)

After sourcing Freesurfer, recon-all gives following error:

.../freesurfer/bin/recon-all: cannot execute: required file not found

Other functions, e.g. freeview, mri_info, all seem to work as expected

Would love some help.

Thanks,

Noam
