Wei,

Thanks for the fast response. I'm using parmchk -i FRH.mol2 -o
FRH.frcmod -f mol2.

Normally it works fine for all of the other molecules I've done.
Really weird. Maybe there is something wrong with our particular
compilation of parmchk and I should recompile or something. It doesn't
make any sense to me...

I just checked and tleap loads it OK. So in principle I could just use
the frcmod you just sent and run that through tleap. But it hardly
seems satisfactory.

I am using a local build on a regular 32 bit intel x86 running fedora core 4.

Let me know if you have any brilliant ideas. As I said, parmchk
normally works fine (I use it all the time), so I dunno why it's seg
faulting on my machine with this particularly mol2 file but not on
yours...

Thanks
David
