IndexError in LocalMinimumClustering #728

Open ershockley opened 5 years ago

ershockley commented 5 years ago

There is a fairly rare error in LocalMinimumClustering - see the full trace here. I can reproduce on both OSG worker nodes and the login node with this:

(pax_v6.10.1) [ershockley@login ~]$ rucio download x1t_SR001_181116_2213_tpc:XENON1T-23838-000429000-000429999-000001000.zip --rse UC_OSG_USERDISK
(pax_v6.10.1) [ershockley@login ~]$ mv x1t_SR001_181116_2213_tpc 181116_2213
(pax_v6.10.1) [ershockley@login ~]$ paxer --config XENON1T --input 181116_2213 --output 181116_2213

I haven't looked into detail yet what is actually causing the error.

This is Run 23838, Event 429274, but so far I've seen the error in two of the huge Kr83m runs that had to have the zip files resized (I think eventbuilder was run on them again? Not really sure how we did that). Maybe this error is related to that. I'll keep looking to see if it comes up in any other runs, but wanted to start an issue in the meantime.

Another error in large Kr83m runs found in https://github.com/XENON1T/pax/issues/729, not sure if it's related.
