Hi,
Thanks for the prompt responses. I checked the distance between atoms
908 and 913 in VMD and got 0.396nm, which seems fine. I thought then, that
my problem may be with my box size when I used editconf. When I changed
the box dimension to 2.0nm from the molecule periphery, the warning between
atoms 908 and 913 disappeared. However, I then recieved a similar error
warning: interaction between 911 and 932 at distance 6.244 which is larger
than the 1-4 table size 1.000 nm
I checked atoms 911 and 932 using VMD, and they don't appear to be close at
all, and their distance is in fact 6.244nm. Does this mean that there is a
problem with my topology file?
Yep - as I guessed earlier, I'd still guess your topology doesn't match
your starting structure.
My topology file is the same as that given
on Tieleman's site, except that I removed #include "lipid.itp". This was
giving me an error, and I did download the ffgmx_lipids.tar.gz file from
the Gromacs site, which seemed to solve the problem.
These things are very brittle - removing an #include is one of the
simplest recipes for a problem I can think of. Fix this problem, and if
you still have problems, then run cpp on the .top file to pull in all
the #inclusions and go through the result with a fine-tooth comb and see
that it all makes sense with respect to your structure.
So, I am not sure why
this error is occuring. The problem could be with my em.mdp file.
Nah, looks fine, except that pbc=full isn't defined in the manual. I do
remember hearing about it once, but perhaps you should try pbc=xyz instead.
