<div>Hi Paul,<br>
yea! I see a very similar thing. I run single threaded but with two different groups<br>
once using hd_root and once using hd_dump both with my plugin. The group<br>
using hd_root is consistent in itself and the group with hd_dump agrees with<br>
the group of hd_root except for one run! And yes its event 1339!<br>

<div>I ran 32 single-threaded jobs with the new software, and I see nearly identical results, but not quite. Half of the REST files have one identical file size (and identical contents), and the other half have a different identical file size (and identical
contents). This is true whether I run with saving the time-based tracking results or the wire-based tracking results to REST. The attached "diff" files show the difference for each case (via hddm-xml). </div>
<div><br>
</div>
<div>This difference is isolated to one event: #1339 in the file I linked everyone to a week ago. In fact, while three wire-based and time-based tracks are listed, they all have the same candidate id: 2. </div>
