#81 problem in merging several roodatasets
I have a problem when merging roodatasets. I use a very simple macro (in attachment) to merge several datasets I have created with grid jobs, however it gives me a std:bad_alloc error (so it seems that it uses all the available memory in the system). The macro is working perfectly if I reduce the amount of data.
I send you the Macro and the Makefile used to build it. I send also a data.txt file to use the macro (if you have an lxplus cern account). Could you have a look to it? Or could you indicate me a different way to merge roodatasets?
Cheers,
Francesco
