Re: Problems with cosmics triggers files (fwd)

[David Lawrence <davidl@jlab.org>]

Hi Andrei,

    OK I guess we got one step closer, but not all the way there. The 
TTree entries seem to be copying except for the contents of arrays. So, 
things like "trig" and "adcsumN" are fine, but not the individual ADC 
and TDC values in "n3" and "t3" etc..

    It is not immediately clear to me at this point why it is failing to 
copy certain branches but not others. I will look at it some more and 
will let you know when it is resolved.

Regards,
-David
