Hello,
I found a possible bug in mri_surfcluster, but it may be linked specifically to average7 and no other srcsubjects (but I haven't checked that). When I run mri_surfcluster with cluster simulation data, the size is reported at a seemingly arbitrary number, based on the fact that the #of vertices does not change. And the mgh output in null (a blank surface is displayed).
However when I run mri_surfcluster with cluster simulation data, but specify srcsubject, it works correctly. This seems like a bug, because I think when surfcluster runs csd files it reads the srcsubject from the csd files, and no other srcsubject should be compatible with the data, therefore it must know the srcsubject in both usages, but in one case it works and the other it doesn't.
Thanks, Rob

*Apparently this is the right way to do it: with csd files, but specify srcsubj average7:*
