Is the subcollosal gyrus included in the ACC label from the cortical parcellation of Fischl, 2004?  We are using the ACC label to constrain Monte Carlo simulations to the ACC.  A max vertex for an ACC cluster has the annotation G_subcollosal, but is listed in the ROI-constrained surfcluster as being in the ACC.  We are using average7 to display our data, if that makes any difference.

Is the subcollosal gyrus part of ACC -- I didn't think it was. 

Is the ACC label too generous if it is including it?

thanks for the clarification,
