Hi, I have made some good progress on reading in LCIO Tracks from the HPS reconstruction into ROOT. Please see this Evernote page for details. https://www.evernote.com/shard/s106/sh/643ca5d0-bd3f-4767-9c99-f93265d551be/f96daef64927b8ad3e70009d272ae9ca The example script (linked from bottom of note page) shows how to open an LCIO file and make a few simple plots of the Track parameters and momentum distribution. It can be used as a starting point for further work. Let me know if you have any questions/comments. --Jeremy ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
