Hi all,
Does periodic boundary affect the calculation of hydrogen bond if my
protein is not in one box? What about other calculations?
Thank you,

Hi Eric
Thanks for doing that great job concerning the amberFF for GROMACS.
I recently came across this paper:

I've been running on 16 processors a protein MD simulation. During the
simulation I've got a crash and the standard error reported this:
Fatal error: ci = 10280 should be in 0 .. 10050 [FILE nsgrid.c, LINE 218]
[0] MPI Abort by user Aborting program !
[0] Aborting program!
What could that be?
Hi Tang Jiaowei,
g_hbond takes periodicity into account, like most tools do. Do note
that this doesn't work if you've performed rotational transformations
(lsq-fitting).
Cheers,
Tsjerk

Right, but I can just warn anyone.
Trying to use TI on a docked structure is insanity...
The docked structure is an approximation in its best case (more likely
its simply crap). Applying a free energy calculation towards such a
structure will give you everything...but sure not the the correct

Hi Maik,
These updated NA params would be nice to add and test, but I've been too
busy lately to do this. I'd like to get to it soon though (i.e. this year
;o)
As for AMBER-99SB, the paper makes reasonable arguments I think, but I've
not run any real test or production runs with 99SB
Hi all.
I'm writing this beucase I'm having terrible problems in trying to deal with
gromacs trajectory files with my own programs, originally written on
fortran90.
The codes themselves are enoughly big to make it out of question to try to
translate them. What leads to some sort of mixed
Hi,
try:
download
http://www.mpibpc.gwdg.de/groups/de_groot/xtc.tar.gz
(and optionally issue a 'make' in the xtc directory after unpacking)
in the linking stage, use something like
ifort -blabla -lxdrf -L/wherever/xtc -lg2c
your smalll test code looks OK apart from the fact that I don't know
