[Inconsistency?] ROOT 6.06 vs. 6.10
https://forum.gsi.de/index.phpindex.php?t=rview&goto=21900&th=5907#msg_21900
We found a severe inconsistency between a minor step-up from ROOT 6.06 to 6.10, effecting our simulations. I tested a FairSoft oct.17 release with FairRoot 17.10a. I installed a second version with the older ROOT version, in order to pin the issue down to ROOT.
From the release notes of ROOT I found that the geometry classes were subject to a larger change in ROOT 6.08.
The effect is, that the track length in the STT (see attached pdf, page 2, upper row, middle) is capped at about 1000.
Did anyone see that effect, too?
Cheers!

Number of secondaries? energies?
It is very strange that not all detectors are affected.

Yes, we have that already in the MCTrack banch. Good call.
Plots in the pdf below.
This is really worrying.]]>Ralf Kliemt2017-12-06T09:58:40-00:00Re: [Inconsistency?] ROOT 6.06 vs. 6.10

I contacted Roman to investigate further. Attached you'll find my comparison plots with and without the whole DIRC.

the issue is connected to the TGeoTubeSeg volume which has problems with new fairsoft packages (root6.10/geant10.2 ?)
I replaced it with TGeoTube with some volume subtraction. With new geometry it looks like everything is fine again.

The problems become less. That's good.
You can find the comparison between the root versions below.

In addition the number of secondaries seems to be less in Root 6.10 (at least the MCTrack.fMotherID does not extend to numbers beyond 800).
What is the suggestion to proceed?
Cheers,
Tobias

Since we're looking at a "fresh" bug by root I favor to make the release with Root 6.06, i.e. the "old" FairSoft/FairRoot combination, which is running well, so far. The bug in root seems to be addressed already in their master branch (thanks Radek!) and we shall simply skip the latest FairSoft release until we get the fix.
In the future we'll be more flexible with the alibuild structure!
