Hi Maria – Can you please run the mri_info command on the same nifti volume on the same computer and let us know what the output is?

Dear Freesurfer community,

I'm having trouble completing the pre-processing step for TRACULA analysis. I'm using a single NifTi file which I've converted using the original DICOMS, acquired by a PHILIPS scanner. However, I get the following errors in the command line:

dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address Referenced from: /Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib Expected in: /usr/lib/libSystem.B.dylib

trac-preproc exited with ERRORS at Wed Jun 21 16:22:34 BST 2017

I double-checked my configuration file and everything (bvals and bvecs) looks like is formatted appropriately. I also tried running the command with -i and -s flags, but i get the same errors. Please find attached below the trac-all.log

I would really appreciate any advice as to why it's not working and what I might be doing wrong!

Many thanks, Maria.
