EVIO-support to the nightly builds and the most recent release

<h2> <span class="mw-headline"
id="Review_of_Minutes_from_September_17">Review of Minutes
from September 17</span></h2>
<p>We looked over the <a
href="https://halldweb1.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_September_17,_2014#Minutes"
title="GlueX Offline Meeting, September 17, 2014">minutes</a>.
</p>
<p>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.
</p>
<h2> <span class="mw-headline" id="Commissioning_Simulations">Commissioning
Simulations</span></h2>
<p>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.
</p>
<p>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.
</p>
<p>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.
</p>

<p>Paul moderated the discussion.

<h3> <span class="mw-headline" id="Online_Monitoring_Histograms">Online
Monitoring Histograms</span></h3>
<p>Kei summarized the status of the online monitoring plugins in
the following table:

<p>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.

<h3> <span class="mw-headline" id="Monitoring_Database">Monitoring
Database</span></h3>
<p>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.
</p>
<h3> <span class="mw-headline" id="Run_Browser">Run Browser</span></h3>
<p>Justin reminded us of the location of the <a
href="https://halldweb1.jlab.org/cgi-bin/data_monitoring/monitoring/runBrowser.py"
class="external text" rel="nofollow">Run Browser</a> and <a
href="https://halldweb1.jlab.org/cgi-bin/data_monitoring/monitoring/timeSeries.py"
class="external text" rel="nofollow">Time Series</a> webpages.
Results of the monitoring effort will appear there.
</p>
<h2> <span class="mw-headline" id="EVIO_to_ROOT">EVIO to ROOT</span></h2>
<p>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.

normalization. (Sean, Richard)
