You can have a look at rms.xvg file, it contains rmsd values.

If your residue contains new atom types, you should add them to the
atomtypes.atp and ffnonbonded.itp files.

You can reduce your box size to get a smaller system.

So does it means the mass and charge of [ atomtypes ] section could be
modified in [ atoms ] section?

Hi everyone,
I generated a .top file of a ligand using acpype for MD simulations. There
are some new atom types in [ atomtypes ] section, but the data of mass and
charge columns of the section are zeros. However they can be found in the [
atoms ] section. Can you tell me if this file is ok for MD s

Thank you. I have found a tutorial and I will try to derive them.

Hi everyone,
I want to simulate a protein-ligand complex. The ligand is a GppNHp
molecule and an analogue of GTP. I cannot find parameters of GppNHp in
AMBER parameter database (parameters of GTP are supplied there). Can you
tell me how to get the parameters of GppNHp? Thank you in advance!

Hi,
I think some crystal water molecules are important to my the system. Can I
keep the crystal water molecules when I run a MD simulation with implicit
water model?
Thank you in advance!
Best regards!

Hi everyone,
I did two reMD simulations with GB implicit solvent and TIP3P solvent using
Gromacs4.5.5 respectively (1 cpu per replica for both of them). My results
show that implicit solvent model is not faster than explicit solvent
model. I'm confused why the implict solvent model is so slow? Or s

Hi,
I want to simulate a protein-ligand complex with implicit solvent. After I
ran "grompp" command it prompted me there were some missing GB parameters.
I guess the problem is that some atom types in my system are not included
in the gbsa.itp file.
If it is the case, do you know where can I find t

Maybe you can dump the frame at t=50 ns using "gmx trjconv" and use "gmx
grompp" to do an extending simulation when you don't have a .cpt file. Of
course this is not an exact continuation.

Hi
I have completed a protein-ligand MD simulation using Gromacs v4.5.5 and
found protein undergoes a large conformational change. But sampling is too
sparse to get intermediate states. In order to get some intermediate
states I have to rerun the confromational change period of trajectory with
