It works now !
I tried to remove the gROOT->Reset(); but it doesn't make any difference.
But naming the macro void sphericalLEFS60() does !
I don't understand, since I've been using unnamed macros all the time, and in the manual the macro is also unnamed, but well, such a simple thing solved the problem ... I would still like to know why tough. Anybody can explain?
Anyway, thank you for your help,
Bruno
I send you the output with thetreeFile->ls() and myTree->Print() before I named the macro, in case it's of some interest.
