Hello,
if I try to run the macro/runDigi.C macro, after copying the *.dat and *.asc files in the directory where I launch the macro, I get the following error:

-I- CbmFieldMap: Reading field map from ROOT file /home/spataro/pandaroot/input/TransMap.root

If I have understood well the file DevMap_29-06-07_E_and_B_new_fieldclass.dat is missing, somewhere.
The same problem was found by Alicia some time ago.

Is it possible to fix it?
Thanks

Hi!

This is fixed. Turn off the distort option for the drifter task.
The macros are not running out of the box. You should never rely on them as they are in the repository! IMHO that is the point of having macros.

There is no "standard" TPC digitization yet. And I would ask you to be carefull what you present from the results you get from this code.

However I agree that we have to provide all the files and parameters in a proper way. Maybe it would be a good idea to add a better error trap at that point.

Cheers! Sebastian.

Hi,
and how to disable the distortion?

I tried commenting out all the functions of TpcDriftTask:

TpcDriftTask* tpcDrifter = new TpcDriftTask();
// tpcDrifter->SetPersistence();
// tpcDrifter->SetTransverseDiffuse(true);
// tpcDrifter->SetLongitudinalDiffuse(true);
fRun->AddTask(tpcDrifter);

(with and wothout persistence) but I got always the same error. I have only to disable tha task to make the macro running, and of course then the latter tasks are not launched.

Hi Stefano

When you look into the header of the task you will find the method SetDistort.

However I have just implemented a better error handling. give me a minute to test, then I will submit it.

Cheers! Sebastian.

Moment,
I found that I have a not updated my version of the tpc code.
Now I am recompiling and I will let you know with the new code

Hi Stefano!

Please use at least revision 1318. Should be much more comfortable now. Also the default is no distortion now.

Cheers! Sebastian.

Ok,
now it works (or at least I get not errors and the categories are filled).

It seems a bit slow... or maybe because I tried it with DPM events at 15 GeV/c Smile

Cool!

It IS slow. The DPM will make headaches but in any case the TPC is a bit beasty. This is because every primary ionization electron is treated individually.

So I have to aks for your patience Wink

Cheers, Sebastian.
