    Review of Minutes from September 17

We looked over the minutes 
<https://halldweb1.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_September_17,_2014#Minutes>. 


Sean has implemented the Jones-Dobbs scheme we discussed for solving the 
[[GlueX_Offline_Meeting,_September_17,_2014#100_ns_Shift_Issue:_an_effective_time_cut|100-ns-Shift/effective-time-cut 
issue] that arises when converting HDGeant's HDDM output to EVIO format. 
Time offsets are detector dependent. One must use the "mc" CCDB 
variation when reconstructing this kind of EVIO-formatted data to get 
the right constants.


    Commissioning Simulations

Sean reported that jobs were run over the weekend, 2 k jobs of 30 k 
events each (1 k of the jobs with field, 1 k without). The success rate 
has not been measured. The cause of many crashes is a problem in the 
BCAL smearing routine. David and Sean are looking at the problem. 
Despite this the data should be usable.

Richard and Justin pointed out that events with hadronic events are not 
useful for rate studies. Sean will put together a configuration for EM 
background only runs so we can get started. Richard also cautioned us 
that the way we are now generating the incoherent photon spectrum may 
change the normalization calculation vis-a-vis the way it is obtained 
when generating the standard coherent spectrum. Sean will discuss this 
with Richard offline.

Richard is ready to include Pavel Detiarenko's physics package into the 
tagger hall simulation. Mark agreed to contact Pavel about when it will 
be ready.


    Offline Data Quality Assurance

Paul moderated the discussion.


      Online Monitoring Histograms

Kei summarized the status of the online monitoring plugins in the 
following table:

Detector 	developing? 	test with data? 	notes
BCAL 	YES 	YES 	
CDC 	YES 	YES 	
FCAL 	YES 	YES 	Matt, Manuel working on plugin
FDC 	YES 	YES 	
PSC 	NO 	NO 	MEPHI students?
PS 	NO 	NO 	MEPHI students?
ST 	YES 	YES 	Eric working on plugin
TAGH 	YES 	NO? 	Nathan working on plugin
TAGM 	NO? 	NO? 	Richard?
TOF 	YES 	NO? 	Alexander, Aristeidis working

Matt asked how histogram/macro selections will work, since not all 
histograms generated in the plugin will be of general interest. David 
reminded us that the ROOTSpy GUI allows the user to select the 
histograms and/or macros results that should be displayed. Different 
detectors are selected on separate tabs in the GUI. There will be a 
default selection done, but private custom selection sets are supported. 
To make a macro available for selection, it needs to be checked into the 
same directory as the plugin code.


      Monitoring Database

Sean has a first draft database ready to go. He has installed it on the 
Hall D offline MySQL server, halldweb1.jlab.org. He is working on the 
scripts to fill it from processing jobs. Mark remarked that his database 
is a candidate for replication to the counting house.


      Run Browser

Justin reminded us of the location of the Run Browser 
<https://halldweb1.jlab.org/cgi-bin/data_monitoring/monitoring/runBrowser.py> 
and Time Series 
<https://halldweb1.jlab.org/cgi-bin/data_monitoring/monitoring/timeSeries.py> 
webpages. Results of the monitoring effort will appear there.


    EVIO to ROOT

David is looking at using Gagik Gavalian's EVIO-to-ROOT tool. I would be 
hard to adopt for our current raw data format, but he thought that if we 
re-write the data, as will be necessary for blocked data, we might have 
an output EVIO format that would match the tool's expectations.


    Action Items

 1. Figure out the incoherent bremsstrahlung spectrum normalization.
    (Sean, Richard)
 2. Give a talk on a software versioning scheme at next week's
    Calibration Meeting. (Mark)
