Re: [Brahms-dev-l] fstree2datamap

Hi Selemon,
    it happened that I had the same problem when I was doing the H1 and 
H2 calibration on dAu runs. You don't need to commit the ascii files 
from last steps to the database in order to do the calibration on 
timeoffset - the following is what I added to the script to load the 
local ascii files from the previous calibrations on adcgain and deltadelay.
//___________________________________________________________________________
  BrTofAdcGainCalModule* tof1_adc = new 
BrTofAdcGainCalModule("TOF1","TOF1 adcgain calibration");
  tof1_adc->SetCalibFile(t1adcgainOption->GetValue());
  tof1_adc->SetLoadAscii(kTRUE);
  BrTofDeltaDelayCalModule* tof1_deltadelay = new 
BrTofDeltaDelayCalModule("TOF1","TOF1 deltadelay calibration");
  tof1_deltadelay->SetCalibFile(t1deltadelayOption->GetValue());
  tof1_deltadelay->SetLoadAscii(kTRUE);
// same for tof2
//___________________________________________________________________________

I did the same to test the dst production. I hope this is right and it 
helps to your problem.

Best regards,
  Hongyan
