Correction: We want to use func_print_timecourse_selection (not labl_save) to output the tables that contain the means across the label (with the bad vertex points excluded by previously done masking). However I think the time course functions are not compatible with the .w file format? Right, Doug?
Then, I guess the question is, how do we mask the bad vertex points out of the time course volumes? -Tommi --- Hi Bruce & Surfers, OK, we created a .w file and it looks at is should so part (a) below is solved. However we cannot seem to extract a list of functional overlay values of vertex points included in a label, which was why we needed to do this in the first place. Our goal is to get rid of some bad vertex points points in our functional overlay by creating a mask that excluded them, then load a label, and use labl_save to create a list of overlay values contained within the label (that does not include the vertex points that were masked away). Bruce, Kevin, Doug, any suggestions?
