It means that file doesn't exist in the working directory.


I would appreciate any help.I am new in using MD and gromacs in particular.



Do all the tutorials you can find until basic workflows become second nature. 
Here are a few:

The number of coordinates must match. See discussion of the [molecules] 
section in chapter 5 of the manual. That's probably what you should fix, 
probably with the number of solvent and ion atoms changing. genion -p 
will do this for you if you tell it to do so.

Dear Suryanarayana Seera

Please check the itp files mentioned in the topol.top and what u used in 
your commands. Especially check the solvent model. May be you have not changed 
that in the topol.top file.

Dear all gromacs users,


I tried the grompp and i got the following error."number of coordinates in 
coordinate file (4INS_b4ion.gro, 90396)
  does not match topology (4INS.top, 90393)".

  Is there any explanation why is this 
happens.I would appreceate any help.I am new in using moleculer dynamics and 
particularly in gromacs.



Atom HA in residue MET 1 was not found in rtp entry MET with 11 atoms
while sorting atoms.

For a hydrogen, this can be a different protonation state, or it
might have had a different number in the PDB file and was rebuilt
(it might for instance have been H3, and we only expected H1 & H2).
Note that hydrogens might have been added to the entry for the N-terminus.
Remove this hydrogen or choose a different protonation state to solve it.
Option -ignh will ignore all hydrogens in the input.

Please check out 
http://www.gromacs.org/Support/Mailing_Lists#Mailing_List_Etiquette for 
advice on how to construct effective requests for help. With only the 
above information, all that can be said is that the tool you were using 
expected residue LYS that was first in some sequence, and that was being 
mapped to .rtp entry LYSH, to lack atom an atom named HA. Background 
information on the required matching can be found in chapter 5 of the 
manual. Details of how the mismatch occurred can only be found in the 
files you have constructed.
