Dear sir,
I want to create S-S bond between two cys in a peptide chain
irrespective of
the conformation of the peptide. I tried this using an option -ss as flag
in pdb2gmx but it failed to create S-S bond. since, S-S ditance was more
in free cysSH cysSH, but i want to bring them together to form

conv the same
message have come but at different time steps.
I am not getting what's happening.
I am waiting for positive response
with warm Regard

Hi all,
I have to simulate peptide with SPC water model.During the simulation
trajectory peptide is some time going out of box through periodic
boundary condition is there but physical prescence of solvent is not
there, i mean if i have to extract water molecule within 3 angstrong
cutoff of pept
any positive response.

ro.Is it a particular ratio
between urea & water molecules for particular concentration ? If it is
then this X.gro file (guanidium + thiocynate ion + water ) will be input

Thanks for provoiding insight.
I have gone through instructions for grompp for EM.I have gone through
manual.I breakup the structure in manageable chunks i.e. i seperately
run the EM & PR for SCN, GUD, Protein individally,every individual run
was successful nothing get breakdown.As pr your's in
thankful to you.

Hi all,
I have been trying to simulate peptide (octa alanine). In genbox i have
inserted 40 molecule of guanidium ion & 800 water molecule (by -ci &
maxsol option in gromacs 3.3.3)then again with genbox i added 40
molecules of thiocynate ion & 80 water molecules as above mentioned way.
When i trie
atom
by replacing water molecule it seems that genion is applicable only for
monoatomic ion.
If i have to do simulation with these polyatomic ions with perticular
salt concentration how do i will perform it.

Hi All,
Myself Kinshuk from IIT-Bombay.I have gone through gromacs mailing list
there i came to know about you while searching the solution of the problem
while running minimization using .tpr in position restraints steps of MD
run.I have been performing simulation of guanidium ion & phosphate
file ffG43a1.n2t not found in current dir nor in
default directories.
(You can set the directories to search with the GMXLIB path variable.)
So how do i will be able to resolve this problem.
If i will be getting any help i will be very thankful for you.

m is fixed and if i have to
generate a system of different molal(different ratio of urea and water),
so will be play with concentration.
If any help i will be getting, i will be very thankful.

Hi all,
i want to confirm whethere there is a distance dependent dielctric
function in GROMACS.I want to use this. Please suggest me the possible

about file corresponding guanidium ion.
I tried to make it with argenine side chain but i have been facing
problem while generating above mentioned file.
