Hello Graham,
The org.lcsim code distribution ships with a simple example of accessing MCParticle information in an stdhep file and histogramming some of the quantities. This is packaged as an example for JAS3 accessible via:

Help -> Examples -> org.lcsim examples -> Analysis101

Documentation can be found on a number of Linear Collider wiki pages, most fully at http://confluence.slac.stanford.edu/display/ilc/Explanation+ of+Analysis101+Driver

One can, indeed, filter events from an stdhep file. Documentation can be found at:

http://confluence.slac.stanford.edu/pages/viewpage.action?pa geId=29924

One can, in fact, easily convert stdhep files into LCIO format using the lcio command line tool which ships with the LCIO code distribution. Documentation can be found at:

http://confluence.slac.stanford.edu/display/ilc/LCIO+Command +Line+Tool

Please let us know if you experience any difficulties with the examples, or have any more questions.

By the way, which stdhep files were you experiencing difficulties with? If they truly are corrupted we should fix or remove them from the distribution.
Norman
