Hi FS experts,

I ran into a crypt() error while running the `recon-all` on a test brain with Freesurfer 6.0 installed. The server is an FIPS enabled RHEL7.

In the `recon-all.log`, the error happened after the `mri_convert.bin` execution: ERROR: crypt() returned null with 4-line file

I have attached a snippet below as well as the recon-all.log.

Has anyone encountered this error before? I'm suspecting the issue might be due to the enabling of FIPS on RHEL7. I'm having similar OpenSSL prolembs in FSL/FSLeyes.

Your input is appreciated!

Best,

Sean
