Hello

Printing from StEvent.

Okey so we don’t know if Mudst wasn’t filled correctly on memory, or file writing or reading issues at later stage yet.

Can you re-create Mudst (read mudst -> create StEvent -> recreate Mudst on memory) and see if re-created Mudst on memory is also corrupt?

Then can you check out StMuDSTMaker, and change

COMMON/StMuFcsUtil.cxx

line 173-184

where lines were commented out, put them in, compile and try again?

Is there anything wrong you see from StMuFcsAnaCheckFillClusPoint from StEvent?

Yes I think it is a problem reading/writing MuDsts around cluster-point associations….

Is there anything wrong you see from StMuFcsAnaCheckFillClusPoint?

I haven't seen anything wrong from StMuFcsAnaCheckFillClusPoint.
