External Email - Use Caution
I checked my system is not encrypted. I had someone else run the command on the same machine. It worked for them. So I changed my BASH environment to a default environment. I still get the same error.
I tried this again but with a different FreeSurfer 5.3. turns out the one I was using has been altered version of FreeSurfer. I do not know how it was altered. It worked. so it has to do with the altered FreeSurfer. I ran the command mri_convert -version on both FreeSurfer.
for the unaltered i get the out put
*mri_convert -version stable5* altered version i get
*mri_convert -version dev build (use --all-info flag for full version info)*
with this output i type in mri_convert --all-info *mri_convert ProgramArguments: --all-info ProgramVersion: $Name: $ TimeStamp: 2018/06/12-18:32:17-GMT BuildTimeStamp: Aug 22 2014 21:04:47 CVS: $Id: mri_convert.c,v 1.213 2014/07/29 19:22:31 fischl Exp $ User: tanenbauma Machine: rocky Platform: Linux PlatformVersion: 3.10.0-862.el7.x86_64 CompilerName: GCC CompilerVersion: 40400* Wondering is this version of mri_convert a developmental version? Also both version are the CentOS 6 build.

Hello Aaron,
You could check to see if the CentOS 7 system is using disk encryption, e.g., if the following command return 1, then it would mean encryption is in use (which can be an issue with FreeSurfer).
$ cat /proc/sys/crypto/fips_enabled
If it returns zero, it could be an issue with a system library like glibc on CentOS 7.5 (that does not happen on older versions of CentOS).
Either way, this is not your doing ;-)
