Hi,

These might be old questions, but I couldn't find any entries related to them in the archives.

1. In the surface and volume csd files, what are the units of the

"maxclustsize" columns? Are they mm^2 and mm^3 for surface and volume, respectively? Or are the voxel / vertex counts?

mm^2 and mm^3

2. When mri_surfcluster uses a csd file to compute the cluster-wise

correct p-values, how does it do that? Does it only use the maxclustsize? Or does it take other columns, such as maxsig, into account as well?

It can do both. The output surface overlay specified by the --vwsig will give you a map corrected voxel-wise using maxsig. The --cwsig output will give you the clusterwise correction. To get more info, run mri_surfcluster with --help. doug

Thanks!

Best, Shanqing Cai
