Hi all,

	hope you are doing fine. I am looking into the calibrations for
H1 and H2. It seems that I need to run over gtr files. To get started, I
run the script "TofTdcGain.C" with one of the recent gtr files in
/brahms/data21/data/run05/cucu/200/r12505/gtr/. However the process
breaks with the error message:

Looking at line 334 in BrTofTdcGainCalModule.cxx, I find the line

	fCalibration->SetTopTdcGain(i,1/pol->GetParameter(1))

It is not quite clear from this point on what and where the problem is.
It may be that I need to have some more information besides gtr files.
It would be great and get me going faster if anyone who has done this
before gives me some suggestions and a list of things to make ready for
the Hodoscope calibratios would be nice.

Thanks,
