[Clas12_verystrange] Reconstructed files

[Hicks, Kenneth]

Michael,


Derek has produced a very nice package for this purpose.  I've been using it for several weeks to look at the clas12 data from the KPP run and it works well.  One comment: you need ROOT version 6 to do this.

Derek,

Thanks for the information. I a going to look into the hipo2root code.

Sounds like one could slightly modified hipo2root to skim hipo files for
the  creation root trees and histograms. That is exactly the sort of thing
I want.
