Dear pandausers,
I got a strange error I never met before. When I run a digitization macro I have normal output and then problems with a
TStreamerInfo::BuildCheck and later on error related to TBufferFile::CheckByteCount. My only idea is the problem related to the different version of pandaroot I used when my data was produced.
Could someone comment what is wrong and how to fix it?

The StreamerInfo of class PndMdt read from file

has the same version (=1) as the active class but a different checksum.
You should update the version to ClassDef(PndMdt,2).
Do not try to write objects with the current class definition,
the files will not be readable.

Hi,
the MDT data members have changed, then you could have problems if you use MDTs. But in theory you should be able to process normally all the other events.
It seems to me the crash is comsing from something different:
Error in <TBufferFile::CheckByteCount>: object of class FairBaseParSet

Warning in <TBufferFile::CheckByteCount>: FairBaseParSet::Streamer() not

Streamer()
It is like you have overwritten the param file, or better the param file was created with an older version of the code and FaseBarPasSet is not syncronized anymore.
In that case I think you have to redo the file again.
But, maybe there is a sort of patch you can try.
Go to another folder, and produce with the current pandaroot a small file with the same macro you have used before. Once you have done this, in the folder you will have the mc file and also the param one.
Now, try to use the new param file with the old file. I am not sure if this will work, but maybe if it does you can avoid to rerun everything. Of course, if your original files are "very" old, you are forced to rerun everything anyway.

This will not work, each run has a unique id, and the parameters are initialized for the run id that is in the event header.
