Just downloaded and tried again and I get the following error in the terminal complete with a bunch of error messages in windows in suma.

I'm not sure it makes a difference: the overlay I'm using was @auto_tlrced to TT_icbm452+tlrc and I'm trying to use the TT_N27 surfaces.

the top most window says: Error_process_NIML_data: Failed to fetch or create overlay pointer
next two say Error SUMA_iRGB_to_overlayPointer: Failed to colorise plane.
