| - | * **[[2013:groups:tools:LHEF|Update of LHE file format]]**; more information also **[[2013:groups:tools_lheextension| here]]** | + | * ** Update of the LHE file format** The LHE file format has been around since 2006 and at the workshop 2009 there was a proposal for an updated version 2 of the format. Before this meeting additional suggestens were mad, mainly related to the handling of weights [[2013:groups:tools:LHEF|here]] and [[2013:groups:tools_lheextension| here]]. After discussion there is now the following [[2013:groups:tools:LHEF3|suggested LHEF update]]. |

| + | |||
| + | Other suggestions did not seem to have enough critical mass. | ||
| + | We are happy to schedule additional tutorials if enough people using the programs want them, otherwise users and the authors can discuss in private. | ||
