I would like to get your help.  I extracted cortical thickness values from each vertex from each of my individual subjects (example: path/subject_id/surf/lh.thickness.fsaverage.mgh).  I then ran a covariance analysis over the whole group and identified "modules" or groups of vertices that covary together.  The modules are given the names of colors.  I end up with a module (color) assigned to each vertex.  I now want to visualize this data (so I can if these module reflect specific neuroanatomical structures), but I'm not sure about how to do this.  Does anyone know how to do this?  I tried to make a new color table, with my different module colors as the structures.  I don't know how to then incorporate this information so that I can view it.  I've read the tutorials on the label and annotation files, but I have only become more confused.  If anyone can help me with this problem, I'd be very greatful!
