[Castor-users] castor-GATEMacToGeom/GATERootToCastor questions

[tmerlin]

Hi Niccolo,

Thank you for your helpful remarks. The GATE utilities indeed require 
some corrections and will be patched soon (current month). For the 
moment, please try the code in the zip file enclosed to this mail which 
should address point 1) and 2).

For 3), there is no current plan to support aliases. I will look if it 
is possible to implement it in the next patch though.

4) seems looks like a path issue indeed. We'll have a look at it for the 
next patch. For the moment, absolute patch should work fine.

Best regards,

Thibaut
