and to follow up on my previous mail, I absolve xleap of blame, since this
version works:
> source leaprc.ff99SB
> foo = sequence { ALA ALA ALA }
> impose foo { 2 } {{ N CA C N -40.0 }}
as it should. Also, when ff10 is used, only those dihedral impositions
fail that contain the backbone atom 'C'.
So either I am overlooking something strange here, or there is some kind
of bug in ff10 that prevents imposing dihedrals on peptides?
Kind Regards,
