Hi,<br><br>These might be old questions, but I couldn&#39;t find any entries related to them in the archives.<br><br>1) In the surface and volume csd files, what are the units of the &quot;maxclustsize&quot; columns? Are they mm^2 and mm^3 for surface and volume, respectively? Or are the voxel / vertex counts?<br>

<br>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?<br><br>

<br clear="all">Thanks!<br><br>Best,<br>Shanqing Cai<br>
