1.11</a>. Some bugs were fixed, BGRATE calculator
now working. Version 1.12 on the way.</li>
<li> <a rel="nofollow" class="external text"

from CCDB</a>. Sean went over the description of the
new feature. Each HDDS XML file is a separate type in
the CCDB.</li>

<h3><span class="mw-headline"
id="Review_of_minutes_from_the_last_meeting.5D">Review
of minutes from the last meeting]</span></h3>
<p>We reviewed the <a
href="https://halldweb.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_November_15,_2017#Minutes"
title="GlueX Offline Meeting, November 15, 2017">minutes
from November 15</a>. Unfortunately, we should have
been reviewing the <a
href="https://halldweb.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_November_29,_2017#Minutes"
title="GlueX Offline Meeting, November 29, 2017">meeting
on November 29</a>. No matter; we did establish that
people seem happy with the new work disk. At least no
complaints have been lodged.

<h3><span class="mw-headline"
id="Review_of_recent_pull_requests">Review of recent
pull requests</span></h3>
<p>We went over the <a rel="nofollow" class="external
text"
href="https://github.com/JeffersonLab/sim-recon/pulls?q=is%3Aopen+is%3Apr">list</a>.
</p>
<ul>
<li> Richard [checked in a fix] that restores the
ability of HDGeant to read in a file that it had
previously output, and re-simulate the events.</li>
<li> Richard created a branch of HDGeant4, <a
rel="nofollow" class="external text"
href="https://github.com/JeffersonLab/HDGeant4/tree/primary_pion_zapper">primary_pion_zapper</a>
to support Mike McCracken's study of decaying pions.
Mike wanted events rich in decaying pions, without
simply shortening the pion lifetime in the simulation,
which would give an artificial spatial distribution of
decays. See also the <a rel="nofollow"

<h3><span class="mw-headline"
id="Review_of_recent_discussion_on_the_GlueX_Software_Help_List">Review
of recent discussion on the GlueX Software Help List</span></h3>
<p>We went over <a rel="nofollow" class="external text"
href="https://groups.google.com/forum/#%21forum/gluex-software">items
from the last two weeks</a>.
</p>
<ul>
<li> Sean told us that the <a rel="nofollow"
class="external text"
href="https://groups.google.com/forum/#%21topic/gluex-software/abL_dTh51eg">missing
channels in translation table</a> error that Matt
Shepherd reported was due to the trigger routine
masking FCAL channels, as it does on real data.</li>
<li> On an only-tangentially-related topic, Sean
mentioned that we are overdue for a new release of
CCDB. There are useful features on the master branch
that are not present in any release thus far.</li>
