Hi gromacs users.
I need help with the old data generated by gromacs. It is about a year older.
I used the command and the output is:

Hi Gromacs Users,
I used gromacs in 2007 and have data of that and now want to used that data by
making graphs but the following errors occured:
1) Input output file error.
2) Fatal error. version 40 with version 20 program.
I think I used some version of gromacs 3.0.3 or other at
Hi All,
I have MD simulation which crashed and I combine the frames with trjconv. Now
the problem is that when I do analysis like that of Solvent accessible surface
area, it showed that the incomplete frame . I use the gmxcheck with the
following result

Hi All,
I want to study and calculate the secondary structure as a function of time of
my MD simulated protein. I have no DSSP installed but will use VMD for this.Can
any one suggest me which files of MD simulation output I should used? or I need
to develop PDB file of the whole MD simulation
Dear Mark,
Hi ! Currently I tried to install xmgrace but the toolbar menue is not shown on
window screen so I am using gnuplot for analysis as I have little know how
about unix/linux.Please set to me the following.

Dear Mark,
Hi !
Is there any alternate software to xmgrace, which I can use for my MD
simulation results and which is compatible with gromacs? As I have installed
xmgrace in my computers but the xmgrace window icons and tool bar is not shown
properly.

I have taken the GTP topology from PRODRG server but now how can I make a

what does it means? I am using OPLS/aa force

triphosphate) and other without it.The without GTP MD simulation I have done,

I used the same topology and gro file already used for the first mentioned
temp.But when I used these and give the command
