Hi all,
I'm having an odd issue where leap seems to be hanging when I try to write
my prmtop/inpcrd after loading in my frcmod- ie, when I run
source $AMBERHOME/dat/leap/cmd/oldff/leaprc.ff94
> loadamberparams frcmod.ic5
> loadoff test.off
> m1 = loadpdb ic5.pdb
> saveamberparm m1 test.prmtop test.inpcrd
>
> saveamberparm m1 ic5.prmtop ic5.inpcrd
> Checking Unit.

It'll hang there without writing anything. I figured it seems to be tied to
the dihedral/improper portion in my frcmod (attached) since when I remove
those sections, it starts complaining

So as far as I can tell, it is reading the frcmod correctly- but is stuck
on the writing part in some way linked to the dihedrals?
Best,
