Hello all, When loading markers from a cmm file (example attached), is there a way to specify which submodel the marker goes to rather than it creating a new id? I've added the id_string to the cmm file when I created a new one which is the desired model. I hacked the following, which works, but there are hundreds of tracks so I would like to come up with an automated (and proper) way to do this. perframe "rename #2.$1 track_1 id #1.$2.2;" ranges 1,113 ranges 4,116 perframe "rename #2.$1 track_2 id #1.$2.3;" ranges 114,259 ranges 5,150 Brandon Scott, PhD CZI Imaging Scientist, Research Assistant Professor Nanoscience & Nanoengineering South Dakota Mines 501 E.
