[Gate-users] TTree and TFile Errors during benchmark

[Soultanidis, Georgios]

Dear Gaters

I would like your help for an issue that troubles me. I installed Gate V6.1 successfully and, when I run the Benchmark PET, after a short period, I receive error messages with this form:

Error in <TTree::Fill>: Failed filling branch:Coincidences.comptonPhantom1, nbytes=-1, entry=231026
 This error is symptomatic of a Tree created as a memory-resident Tree
 Instead of doing:
    TTree *T = new TTree(...)
    TFile *f = new TFile(...)
 you should do:
    TFile *f = new TFile(...)
    TTree *T = new TTree(...)

I would like to know if anybody faced the same problem.
Thank you in advance for your help.
