GlueX Offline Meeting, June 11, 2014
Minutes
* CMU: Will Levine, Paul Mattione, Curtis Meyer
* FSU: Aristeidis Tsaris
* IU: Kei Moriya
* JLab: Mark Ito (chair), David Lawrence, Simon Taylor
* MIT: Justin Stevens
* NU Sean Dobbs
* UofR: Tegan Beattie, Zisis Papandreou
Announcements
* A minor-version-change release of CCDB is now available, ccdb_1.01.
It incorporates David's recent change to treat row-wise
one-dimensional constants sets the same as column-wise ones.
* Data Challenge 2 REST file transfer from UConn to JLab is complete.
All files have been archived to tape. There were issues with
multi-stream transfers with the SRM, so only single stream was used
throughout. The suspicion is that the problem is due to small file
sizes. Transfers from Northwestern are next. The Computer Center
has opened up the requisite ports.
* Zisis commented on the state of the software getting-started
documentation on the wiki. We all acknowledged that this is
problem. In particular he pointed out that new students' progress
is impeded by a lack of clear direction in installing the GlueX
software. This must be advanced in priority by this group.
Review of Minutes from the Last Meeting
We went over the [24]minutes from the May 28th meeting.
* Simon has changed the code to get the parameter for the minimum
number of hits on a track candidate from a JANA configuration
parameter. Formerly it was hard-wired at 6.
* Curtis reminded us that we would like to have some kind track
quality information, other than chi-squared, for example the number
of "missing" hits, included in the REST output.
Specifying Alternate Versions of Calibration Constants in JANA
Mark led the group through [25]his wiki page, based on an email from
Dmitry. At the last meeting Justin had asked for guidance on this
subject.
CCDB Schema Changes in Version 1.00
We looked at another of Mark's [26]wiki pages, describing the
relationship between database schema versions and software version.
Again the presentation was based on an email from Dmitry.
Reconstruction of EVIO Data
David brought us up-to-date on the status of doing reconstruction with
EVIO data derived from simulation output. See his [27]his slides for
details. Topics covered:
* EVIO vs. HDDM
* Converting HDDM to EVIO
* Translation tables
* Configuration parameters for the rawevent plugin
* Reading EVIO data into DANA
* Configuration Parameters for the DAQ plugin
* Still to do
We are very close to having a functional system to go from simulated
HDDM to EVIO to reconstruction. The only piece missing now is EVIO data
as it will appear from the CAEN TDCs.
BCAL Truth
Will explained in more detail the mystery he sees in the [28]simulation
output (scroll down to the attachment) that is likely responsible for a
late tail in the BCAL time distributions for pions. He sees a pion
interact in the BCAL and
3.5 ns after the pion dies, in the exact same location as the pion
death, a proton is "born". In addition to this proton, 3 other
protons, 1 neutron, and 1 pion are also "born" at the exact same
moment and location.
We did not come up with an explanation for this. Zisis noted that the
output looks like it comes from GEISHA. Irina Semenova may be able to
help us with this; Zisis will ask her about it.
