Hi Edward

it's because there is a space in the name of your file. This always complicates things in unix and you are better off avoiding it.

Dear colleages

I am trying to convert my dicom files to .mgz from Freesurfer by using the mri_convert comman d, but it provides me the following error:

edward-virtual-machine:~/freesurfer/subjects/Artists/Controls/C1> mri_convert /home/edward/fr eesurfer/subjects/Artists/Controls/C1/mprage grappa2x_i0001.dcm mri/orig/001.mgz mri_convert /home/edward/freesurfer/subjects/Artists/Controls/C1/mprage grappa2x_i0001.dcm mr i/orig/001.mgz mri_convert: extra argument ("mri/orig/001.mgz") type mri_convert -u for usage

Could anybody help me with this problem? Thanks in advance -Edward
