Hi Dustin,
Thanks for all this detailed information and the very useful EPU_group_AFIS.py script. I am wondering if it is also possible to create optics groups from the .gtg files generated by Gatan Latitude S Software? I am currently processing several dataset collected using the Gatan Latitude S software. I am pretty sure the data collection utilized a strategy similar to EPU AFIS, but I don’t know how to read the beam shift data from the .gtg file associated with each movie file. It would be great if the EPU_group_AFIS.py can also extract such information for datasets collecting using Gatan Latitude S.
