separating slash in branch name hinders easy plotting

[bl0x]

The choice of the "/" character as a separator here:

Gate/source/digits_hits/src/GateToTree.cc

Line 340 in 902efda

ss << system->GetOwnName() << "/" << m_outputIDName[k][depth];

hinders easy plotting of the affected branches in the ROOT tree browser.

I'd suggest to use an underscore instead.

The same is also done for the Singles tree:

Gate/source/digits_hits/src/GateToTree.cc

Line 493 in 902efda

ss << system->GetOwnName() << "/" << m_outputIDName[k][depth];

and for the coincidences:

Gate/source/digits_hits/src/GateToTree.cc

Line 667 in 902efda

ss << system->GetOwnName() << "/" << m_outputIDName[k][depth] << side;

[bl0x]

I can confirm that replacing the "/" with an "_" makes the problem disappear.
