ROOt & ASTROROOT libraries

ROOT

Hi,

I installed ROOT 5.02.00 and AstroROOT . I then tried to produce a Ttree from a fits file. So I ran tf2tree in /root/bin. Apparently I can produce a root file from the fits file but when I try to open the file with ROOT I get this error message:

Attaching file a.root as _file0…
Warning in TClass::TClass: no dictionary for class TFIOElement is available
Warning in TClass::TClass: no dictionary for class TFHeader is available
Warning in TClass::TClass: no dictionary for class TFAttr<bool,BoolFormat> is available
Warning in TClass::TClass: no dictionary for class TFBaseAttr is available
Warning in TClass::TClass: no dictionary for class TFAttr<TString,StringFormat> is available
Warning in TClass::TClass: no dictionary for class TFAttr<double,DoubleFormat> is available
Warning in TClass::TClass: no dictionary for class TFAttr<int,IntFormat> is available

To me it seems to be a problem with the ROOT libraries. I followed completely the installation procedure for AstroROOT as in

isdc.unige.ch/index.cgi?Soft+astroroot

Thanks a lot,

Sabrina

Sabrina,

This Warning is normal when you connect a ROOT file and you do not have
the shared library containing the referenced classes.
In this case, you can still work with the Tree (to make histograms or cuts
with the leaves), but obviously you will not be able to call functions of these classes.
