Hi Freesurfers,

Could you help me interpret this error message? I am attempting to run TRACULA using version 6 on a MacBook Pro OS X El Capitan Version 10.11.3

It says at the end that the input file needs to be in nifty format, but my input file is in nifty format. Do you guys have any idea what could be going on here. I attached my dmrirc.example file for your reference as well.

Thank you,

Marissa
