hi everyone,
i installed two new versions of root on the spuds and blast
computers:
the recent cvs version (use the command 'r'), and the latest release
v3.03.09 (use 'rp'). note that the version we have been using
(v3.02.??) is still available with the regular command 'root', and is
still need to run 'ntuple.C', (it used libBlast.so, compiled with
v3.02)
these located at $ROOTSYS_NEW and $ROOTSYS_PRO, including the
sources.
the new version of root is necessary to take full advantage of some
of the features of the 'init.C' macros. two examples:
a) now you can specify hisogram binning right withing the draw
statement:
eep->Draw("atl:ttl>>htemp(50,0,4000, 100,0,8000)")
with the Draw() function from util.C, this can further be
abbreviated:
Draw16("atl:ttl>>50,0,4000, 100,0,8000", "ntl==4&&ntr==#")
b) the standard version was unable to handle graphical cuts on chains of
ntuples (it would crash).
now, you can draw a histogram, create a graphical cut with the
CutG() command,
and then draw another histogram with each cut shown in a different
color.
enjoy!
