Hello, I am a Freesurfer newbie trying to use the mri_convert command to convert IMA format files to either nii or nifti1 format files. Whenever I run the command I get an error at the very end saying that it failed to write (please see below for the exact output error that was displayed). Any help would be greatly appreciated. Thank you in advance.
