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:

We really could use your help, since we can't find any solution in the Internet. Thanks in advance for your attention.
