Matching/merging using madgraphMLM

When producing samples with madgraph and interfacing with pythia, matching/merging is used to avoid double counting between quarks/gluons generated from either matrix-element (hard) or parton shower (soft) (see link). In case your samples require this mechanism, please include madgraphMLM in the dataset name. Additionally, a dedicated study needs to be performed in order to get the appropriate values of xqcut (madgraph) and qcut (pythia). These slides can be very useful as a baseline for this kind of studies.
