Hi,

Does anybody have program for conversion from binary or xml to cern ROOT *.root file?

Thank you for your fast and very helpful replay.

I made it work with drsosc version 4 but with version 5 i am getting weird results. Is it possible that they changed binary formatting?

Please find attached a simple ROOT based program (http://root.cern.ch) to decode binary data from the DRSOsc program. It assumes that all four channels
were recorded. If this is not the case, the program can be adjusted accordingly.
To use it, simply type (assuming that you have written a data file "test.dat" with DRSOsc):

We see quite some spikes in our DRS4 sampled data in FACT.  We see different types of spikes:

    single cell spikes, usually showing a large amplitude of 200mV
    double cell spikes, usually only in the order of 20mV.

   Even triple and quadro cell spikes are rarely seen.

The double cell spikes often occur as symmetrical double cell spikes mirrored
