Re: [Brahms-dev-l] root issue

Another solution that I have used is to load the bdst library.

brat [0] gSystem->Load("libDstData.so")
brat [1] TFile *_file0 =
TFile::Open("/brahms/data21/data/run04/auau/200/r10190/dst/dst010190v0p3.root")
brat [2] T1->Draw("G.fTrigger")

It works this way, greetings
