HI Rene,
thanks for the answer.
I'm having problems finding out in test/Event.h how to write an fMatrix
object to a tree.
There's no implementation of
dataTree->Branch("fMatrix", fMatrix, "fMatrix[io][in]/D");
in the code in test/* files.
I've tried my own
dataTree->Branch("adcM", adcM, "adcM[nCadc][nadc]/D");
but the code crashes:
*** Break *** segmentation violation
Generating stack trace...
/usr/bin/c++filt: unknown demangling style `gnu-new-abi'
running the debugger I got:
[Switching to Thread 1093052608 (LWP 12945)]
0x400e6e86 in TBuffer::WriteFastArray(double const*, int) ()

Do you have any Idea of what is the problem?
