Hello,
I wanted to reconstruct some tracks using lhetrack+genfit, using TPC+MVD.
I have run the macros in macro/pid, exactly:

root run_sim_tpccombi_pgun.C"(500,13,1)"
root run_digi_tpccombi.C
root run_reco_tpccombi.C 


and after a while I get a crash coming from the kalman.
I have modified a bit the class PndLheKalmanTask.cxx in order to have some cout, and this is the error output:

Toggle Spoiler


The initial parameters are, in red: position, momentum, position error, momentum error -> a not so special track.
This track is made of 6 hits, it seems only MVD hits. At the end the error seems in TGeant3::Ertrak () .

If somebody could take a look and hopefully fix it...
Thanks in advance

Hi,

could you please run this in gdb?

gdb root.exe
run youscript.C
where
fr X

where the frame X is the one where the crash happens (xm55).

Thanks, Christian

Under suggestion of Lia, I have modified the geane parameters for the material "air", adding the following lines in gconfig/Geane.C:

TGeoMedium *o=gGeoManager->GetMedium("air");
o->SetParam(3, .4); 


to change the maximum angle of deflection inside the magnetic field.
In this case the analysis proceeds without errors. If I use larger values, such as 0.5 or greater, then I have the crash exactly at the same pointx.
I don't know if maybe it could be good to change this option for the common geane parameters, or if this is just a hard fix...

ADDED 29/08/09
I have tried with a different data set and I have followed in the same problem,. This time I had to go to 0.05 in orer to get rid of that crash. And, once I am applying such lower cuts, I have seen that there are more warnings such as:

FitterException thrown with excString:
cov_is_zero
in line: 257 in file: /home/stefano/july09/pandaroot/genfit/Kalman.cxx
with fatal flag 0

in line: 272 in file: /home/stefano/july09/pandaroot/trackrep/GeaneTrackRep.cxx

Then maybe gendoit is skipping those tracks/reco hits.

Is there a work around for this problem? I have this every time, when running
root run_sim_tpccombi_pgun.C"(1000,13,2,-1)"
root run_digi_tpccombi.C
root run_reco_tpccombi.C
root run_kalman_tpc.C

The actual floating point exception error occurs in
#15 0xae69c5c5 in TGeant3::Ertrak (this=0xa120780, x1=0xd502208, p1=0xd502214,
x2=0xd50217c, p2=0xd502188, ipa=6, chopt=0xa14a7e8 "LE")
at TGeant3/TGeant3.cxx:5402

when it is called by FairGeanePro (the exact place differs).

Gosia Sudol on her 64 bit computer doesn't it have it at all.

You have to copy the file macro/pid/Geane.C into gconfig folder.
If you have again the crash, try to decrease a bit the param for air (do not touch PWO).

This is just a trick, waiting for the final fix of the original fortran code (there is somebody working on it). Once the fix will be released, you will have to use the "official" Geane.C, but for the moment try with this fix.

Hi,

I am trying to keep track of all FPE pitfalls. Can you please give me more exact information on the crash, i.e. the complete stack trace and also frame info of the steps in the stack trace that are inside the fortran code. You can get this if you compiled the external packages with debugging symbols (which it looks like you did) and then start the crashing macro like

gdb root.exe
run mymacro.C
[after the crash]
where
fr N
fr M

where N and M and ... are the frames inside fortran.

In case you knew all this, I want to apologize for telling you again Wink

Cheers, Christian

Hi,
while looking at the crash problem I was printing the magnetic field values read by geane (Hx, Hy, Hz) and I saw sometimes it sees 0, 0, 0 instead of the correct value (compared to the map values)... This is due to the fact that in some materials in the media_pnd.geo file the IFIELD parameter is set to 0 (for example for copper and mylar, two stt media): the STT is inside the magnetic field but geane does not see it in these cases.

Is there any reason why IFIELD must be set to 0 on some materials I didn' t think about?

I think that all the materials which are inside the magnetic field should switch this parameter on (i.e. set IFIELD to 1 and not to 0), otherwise during the geane tracking it will be assumed that here there is no field and the track will not bend inside these materials.

I would change at least copper and mylar (since I saw the problem there), is there any objection? I ask, since not only stt uses these materials.

Best regards,
Lia.

P.S.: Unfortunately this is not the source of the crash, so I keep investigating... please be patient! Rolling Eyes

Yes, thanks very much. This cures it! Very Happy

I didn't get your method to work, but here is all the info I do get. I hope this is enough to work with.

Macro with the crash: run_kalman_tpc.C
Simulated events: root run_sim_tpccombi_pgun.C"(1000,11,2,-1)"

Hi,

it could be that parameters in macros influence the crashing of GEANE. But still these problems should be fixed inside of GEANE. Although GEANE was widely used in the old days without any problems, it could just be that the compilers changed since then. All problems we have in this direction come (as far as anything I saw) are due to overflows in single precisions floats when you assign a double precision value to it (with an exponent >~ 30 or so). We will continue to have these problems unless we do something drastic, e.g. change GEANE to double precision all over. What do the GEANE experts think about this?

Cheers, Christian

Hi,

I'm arriving more or less to the same conclusions, because the
behaviour of the crashes is typical of a bad compilation.
To put GEANE in double precision requires to put the
fortran statement IMPLICT DOUBLE PRECISON (A-H,O-Z) in all
the routines (Variables beginning with I,J,L,K,M,N are integers
in FORTRAN). This could be done in a test version and after
implemented in the CERNLIB.
We will try to do this

Alberto
