Splitting LHEF Event files easily
It is sometimes easier to work with large event files (e.g. to use Decay), but its also sometimes easier to work with smaller samples (e.g. for control samples, to reduce the size of PYTHIA files, ...).
If you need to split LHEF files, please use this PERL script. Download the attachment and then type
mv split.pl.txt split.pl
chmod u+x split.pl
The syntax is
=./split.pl perc out1.lhe.gz out2.lhe.gz in.lhe.gz=
where
perc
is the percentage (between 0 and 100) of events from
in.lhe.gz
to be saved as
out1.lhe.gz
. The rest is saved in
out2.lhe.gz
. All the information (number of events, unit weight, ...) is updated correctly in the banners and in the event XML blocks.
