Sure, you can do this, just don't modify the trunk in svn with any
such customizations, please. What to do:<br>
<ol>
<li>Write your own fortran function custom_decays() and stick it
at the bottom of the file uginit.F -- yes, in fortran ! In
this function you should call gsdk once for each decaying
particle you want to modify." See the link below to the docs
for gsdk.<br>
</li>
<li>Insert a line "call custom_decays" right after "call gpart"
in the body of uginit in uginit.F<br>
</li>
</ol>

Hi,
I had a question regarding the decay modes in hdgeant.
I would like to have control over how my particles decay,
so that I don't waste 1/3 of my CPU on events that do not
have the topology I want.
Is there a way to edit some file and specify what the decay
modes for a given particle should be? I looked around and it
seems like I need to edit something to do with the function
gsdk, but can't find any non-executables with it in the repository.
Does anybody have any ideas?
Thanks,
Kei
