Hello, We are medicine students who are using freesurfer for research. We had been using freesurfer in Ubuntu 12.02 without encountering any trouble; recently we updated to 14.04.
Now, when we attempt to convert a mgz file to nii using mriconvert, we have an error regarding failure to write the files .nii The command we are using is as follows: mri_convert ../estructural/Freesurfer_segmentacion_cortical_resultado/C2090_cortical_seg.mgz ../estructural/Freesurfer_segmentacion_cortical_resultado/C2090_ cortical_seg.nii The error message we find is this one: $Id: mri_convert.c,v 1.179.2.7 2012/09/05 21:55:16 mreuter Exp $ reading from /home/psa/datos_MRI_cerebral/estructural/Freesurfer_seg_cortical_resultado/C2090_cortical_seg.mgz...

Thanks in advance for your attention. Regards, Óscar and Alba
