I am new to conn. I have a set of data already in mni space. When I ran the "Setup", in the Preprocessing I just chose "functional Label current functional files as "mni-space data" & functional Segmentation (Gray/White/CSF segmentation). This step was going through without any trouble. However, when I clicked "Done", it went to the end but gave me the following error:

ERROR DESCRIPTION:

Does anyone has the same problem? What should I do to correct this error?
