To test the latest version of the DetChar tools, I checked the Segment files automatically generated using HTCondor and compared them with those generated on k1det1.

The files from August 19 and 20 were not consistent. The likely cause was that the HTCondor job ran at 0, 15, 30, and 45 minutes past each hour, before all data for each 15-minute period were available.
I changed the schedule to 3, 18, 33, and 48 minutes past each hour, following the crontab configuration on k1det1.
I will check the results again after a few days.
