Hi - this does look really weird - never seen anything like that. I
don't think it's related to the model, which looks fine, but more
likely to something odd in the data.
Do you want to upload the whole .gfeat output and we'll take a look,
Please upload the files in a single compressed tarfile to
http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi
And then email me the upload ID.
Cheers.
