Hi all,

The Mvd test sensors are taking data which I intend to stuff into our pandaroot analysis chain. There is a task developed to read the data and put it into a clonesarray via the framework. (see https://subversion.gsi.de/fairroot/pandaroot/development/mvddevel/mvd/Mv dDAQ rev. 4422)

However, there are some issues with the Run objects: The CbmRunSim is not really a good option to use (it works, though) because you will start the Monte-Carlo which is not needed and which really slows the whole thing down. The CbmRunAna is more preferable, but it reads a TChain, which still has to be created. Especially the Run function is setting the eventnumber according to the Eventnumber in the TChain.

Toggle Spoiler

There are two possible solutions which come to my mind: Either we create a new CbmRun class which is there for taking CbmDetector modules (to have the panda geometry) and a list of tasks OR to set the CbmRunAna into a "DataMode" and simply skipping the eventnumber check in the Run function. Personally I'd prefer to have a CbmRunData (or CbmRunDAQ or whatever).

I'd be glad to hear an opinion on that.

Cheers, Ralf.

Hi Ralf,

you can use the CbmRunAna::DummyRun which does not use any input chain or what ever it just execute your task and fill a tree out of that!

regards

Mohammad

Hello again,

We tried it with the CbmRunAna::DummyRun(). It works so far.

Ralf.

PS: Filesize issues may arise from not clearing the arrays each event.
