[Gate-users] GATE on Linux cluster

[Simon Stute]

Hello,

Just to clarify something that is often discussed and that seems unclear
for many people.
The cluster tools actually support all output formats, in a certain way.

To be as clear as possible -- except the ROOT output, all other outputs
only consist in files that can be either concatenated (e.g. list-mode,
ascii), or summed (e.g. sinograms, interfile, dose maps), so it is supposed
that you can do such simple operations by yourself. Then, the root output
is a sophisticated output format, so to merge different root files, you
need a specific tool: this tool is provided in the cluster tools, included
in the Gate release (or a native root command also exists, but which won't
preserve the eventID coherence with respect to the time).

Hope I clarify something :-)
Simon
