I’m looking into it...

Hello Sho,

The Jenkins system is reporting test failures related to the conditions database. Is it possible that there is something there that is related to this issue? I'm CCing Jeremy, since he might be interested in this if that is the case.

Thanks,

Kyle

Hello Sho,

I am getting a NullPointerException when running the simulation from FADCReadoutDriver. It happens immediately on the first event. The following is the error message:

java.lang.NullPointerException

I have made no changes to the parameters in the driver from what is in the default steering files. If it helps, this is the line causing the error:

noise = Math.sqrt(Math.pow(channelData.getCalibration().getNoise() * channelData.getGain().getGain() * ECalUtils.gainFactor * ECalUtils.ecalReadoutPeriod, 2) + hit.getRawEnergy() / (ECalUtils.lightYield * ECalUtils.quantumEff * ECalUtils.surfRatio));

Do you know why this is happening?

Thanks,

Kyle
