Dear analysts,

I am happy to announce that we think we fixed the remaining problems with the extrapolations. Actually, it was a numerical protection that we built in quite some time ago and that has been removed without my knowledge. There also have been some other improvements in the code.

Please update

tpc/tpcreco
GenfitTools
recotasks
macro/run

I used macro/run/tdrct/run_reco_tpc.C to simulate 1000 muons at 2.0 GeV/c going forward at 18 deg "scattering" angle with real PR. I attached plots of the reconstructed momentum spectra after TPC fit, TPC+MVD fit and TPC+MVD+GEM fit.
I am sorry that this all comes at such a late point in time.


There are quite some issues that need to be resolved now:

  • Which digitization revision are we going for the data challenge and the short-term analysis until Tuesday?
  • The macro/run/tdrct section needs to be cleaned up - how is the conversion to PndTracks and PndTrackCands going to happen?
  • I noticed that the GEMs were removed from the dpm digi macro! Was this done on purpose? I put them back in now.
  • If an update of the TPC digi is performed (be it on the GRID or now in the personal studies of the analysts) the cluster shift in the reco macro has to be adapted (see the comments in macro/run/tdrct/run_reco_tpc.C)! The correlator tasks actually write out histograms of the X,Y and Z residuals that occured during extrapolation of the TPC tracks into MVD and GEM (see reco macro). I ask the analysts to please check the Z residuals. If they are centered around 0, the proper shift has been applied.


I want to thank Dima and Stefano for their help! I apologize again for the chaos. I urge all the analysts to check out the newest versions of the code (in the correct folders, that is) and keep me updated about their results. I also want to make everyone involved in the analysis that in its current setup the reconstruction track fits work on BOTH GEANE and RKTRackRep at the same time. GEANE is set to be the cardinal track representation and is used in the correlators, but one can get both fit results by calling getRep(i), where i=1 refers to GEANE and i=0 returns the RKTrackRep.


Cheers

Felix

Hi Felix,

I want once again report error which I have with tpc reconstruction macro. To be more precise /macro/run/tdrct/eta_c/run_reco_tpc_evt.C
It appeared after removing PndTpcClusterFinderTask task from this macro.

It is solved when I copy NEON-90_CO2-10_B2_PRES1013.asc and two other files from /tpc/ directory to the directory from which I run macro but this solution doesn't work for batch farm. For me it's strange that you don't have it, but may be you have /tpc/ directory set in PATH?

Concerning the conversion to PndTracks and PndTrackCands, you can see how I added the PndGFTrackToPndTrackConvertorTask for conversion into my version of tpc reconstruction macro /macro/run/tdrct/eta_c/run_reco_tpc_evt.C And if it will work, I suppose that it's best way for conversion at the moment.
Hovewer it still needs to be tested. My problem is that with this task and macro running at GSI lenny64 computer I have the following crash (with both GeaneTrackRep and RKTrackRep)

I suppose it's related to memory problem. But with my computer at work conversion worked for RKTrackRep at least for 20 events. I wanted to avoid memory problem running macro at GSI batch farm but the first problem stops me from doing it.

I had the same thing before - has there been some change to the param file recently? Stefano? It was working yesterday, and now the files aren't looked up in the tpc folder anymore, but in the trunk .... This has to be solved! Otherwise we need some links lying in trunk/ ...


Concerning the other crash - this looks still like one of the exceptions we've been seeing in the extrapolations... Are you sure you are running the latest version of GenfitTools/, tpc/tpcreco/, recotasks/ and genfit/ ? What is the version if GeaneTrackRep and RKTrackRep?

If you suspect memory usage - can you check how much the macro is using up?


Cheers

Felix

Do you mean the protection against low momenta? I removed it some months ago since we fixed the realated problem in GEANE (or at lest I thought it was fixed...). I am really sorry if this is the cause of the crash, but I really cannot understand why GEANE started to crash again on low momenta after several months of good work.
After next week I will investigate GEANE in more detail and make a full check, sorry for not beeing able to do it now.

Unfortunately there is also a bad news. With the updated code I get this crash:

when running the Kalman...

However if I use an older revision it works... I saw it on a run of low momentum single track muons and one of electrons (below 1 GeV/c).
...I hope this will not affect channel reconstruction...

Hi Lia,

Quote:

Do you mean the protection against low momenta? I removed it some months ago since we fixed the realated problem in GEANE (or at lest I thought it was fixed...). I am really sorry if this is the cause of the crash, but I really cannot understand why GEANE started to crash again on low momenta after several months of good work.


Yes, it seems that this was the problem. After re-activating these checks I haven't seen any more crashes inside the extrapolations. I will investigate in more details when I have time (whatever this means Smile ).

I had the same thing before - has there been some change to the param file recently? Stefano? It was working yesterday, and now the files aren't looked up in the tpc folder anymore, but in the trunk .... This has to be solved! Otherwise we need some links lying in trunk/ ...




I had the same problem, and I solved changing the clusterization in digi copying the version of the old reco macro -> I suppose some parameter was not stored somewhere because of some flag.
However, the macros are taking all the params by default by all.par, but the .asc files are taking directly from the tpc folder. In all.par there are only the corresponding tpc.par parameters.
I think it just a matter to check the launched macros, to find the "missing" option. When the clusterization was taked out from the reco, something was still missing in the digi, I suppose.

Hi all,

I didn't manage to overcome the problem with
PndTpcGas: Reading data file: NEON-90_CO2-10_B2_PRES1013.asc
Fatal in <PndTpcGas::PndTpcGas>: Input File is not found

in other way than returning PndTpcClusterFinderTask to tpc reco macro.

But than I tried to test the task PndGFTrackToPndTrackConvertorTask for GFTrack -> PndTrack conversion. I put this task to another macro which executed after reco macro and it crashed but this time it was more verbose:

 *** Break *** segmentation violation

So indeed it was not memory probelm. But at this point I'm stuck.

Here GEANE just sets up the starting plane so it would be useful to see which numbers are given as input to PropagateFromPlane, just to see if they identify well a plane or not.

Dear colleagues,

I want to summarize briefly the status of GFTrack to PndTrack conversion.
My last attempt was to perform converion from GFTrack to PndTrack using PndGFTrackToPndTrackConvertorTask in separate macro. And as I have written in my previous post it ended with error:

#5  0x00007f3c8379730f in FairGeanePro::PropagateFromPlane (
    this=0x100000000000000, v1=
0x7fff8ab90990, v2=
0x7fff8ab90960)
    at /d/panda02/dmelnych/pandaroot/pandaroot/geane/FairGeanePro.cxx:384


Origin of this error was that GeaneTrackRep contained non persistent data member FairGeanePro *_geane and reading GFtrack from root file it was udefined, but in turns was used during conversion in PndGenfitAdapters.cxx .
So the conclusion is that conversion should be performed in the same macro as reconstruction.

But here another problem arrise. My initial idea was that it's in some way memory problem, but it looks it's not the case. I observed that crush happend in the moment when the memory still not full.

So it looks like:

GFException thrown with excString:

My observation is that in the cases I observed, the crash is after the message:

RKTrackRep::RKutta ==> Too long extrapolation requested

This crash happen not every event but sufficiently often (after 3-5 events) that conversion cannot be reasonably performed.

Hi all,

once again concerning GFTrack to PndTrack conversion

Here I attached slightly modified version of PndGFTrackToPndTrackConvertorTask, which catch an exception

*** PndGFTrackToPndTrackConvertorTask::Exec	Genfit Exception: GFException thrown with excString:
GEANE propagation failed
in line: 204 in file: /home/dimam/pandaroot/pandaroot/GenfitTools/trackrep/GeaneTrackRep/GeaneTrackRep.cxx
with fatal flag 0


and macro at least is running without interruption.
But still I didn't have time to estimate obtained results.

So could somebody commit the changes to svn?

Correction to my previous post,

I have attached there the wrong file.

Here is the correct one.
