Add MiniRun6.5 Tutorial

[ttdtsui]

Updating the current Workshop Example to MiniRun6.5, some things have changed. Also adding references to the 2x2 wiki so reader can trace the documentations.

Changes

• Use MiniRun6.5 "*_vert" fields instead of the "vertex" field
• Fetch detector boundaries from "geometry_info" instead of hardcoding
• Fix MiniRun6.5 missing final hit backtracking (prompt hit tracks normally)
• Add reference to 2x2 wiki
• Add file locations
• Add reference to mapfiles.py
• Add reference to interactive event display
• Use tables to explain indexing
• Use a table for the Coordinates section
• Expand coordinate description (Since f631ed5?)

Other Ideas

• Display prompt hits by default in the first event display, the segments and fiducial vertices in the 2nd, and prompt hits in the 3rd. And add note to click on the legends.
• mc_truth/interactions/data -> t_event[us](spill/event time) is not recorded anywhere else since 2x2 wiki is outdated.
• Move changes between versions to the end or remove completely; Ideally replaced with a link to a changelog.

Problems

• MiniRun 6.5 charge/calib_final_hits does not have a reference to mc_truth/calib_final_hit_backtrack, so the backtracking sample does not run properly, using a previous version (6.2) creates a mismatch of shape for the same event.
  • I also failed to find an event with 2 prompt hits corresponding to 1 final hit.
• We can have 20 segments correspond to each charge packet in MiniRun6. Is this change permanent and is the description still correct?
• Baseline signal of both light detectors are not zeroed, current solution in event display is to take the average of first 50 samples as baseline, should it be incorporated here?

Hi there! I don't recognise the user name from here but message me on slack if you have chance

@jvmead Hi, name's Dick Tsui. I am just a BSc student doing my final year project on NDLAr so you wouldn't have known me. I am not in LBL and I don't find you on NERSC slack.

Makes sense. If you have a NERSC email address, send it my way and I can forward some resources to you (updated tutorials) and the mailing list for LRO experts on a biweekly call which you're welcome to drop into if you have any questions regarding your work!
