Force-extension curve using simulation data

Can anyone please help me on How to make Force-extension curve using simulation data…

Are you using the pull code to generate these data? It’s a simple matter of plotting the output of pullf.xvg against the displacement listed in pullx.xvg, though you’ll have to do a bit of grepping to pull out the appropriate columns. But the data are all there.

Okk sir i understood this but how do i pull out the appropriate columns from given data…

You can use Python or Matlab to plot the data (google how to plot xvg files, and you will find plenty of scripts). This link might be useful: Import and plot Gromacs .xvg data files - File Exchange - MATLAB Central

Okk… Thank you… I will try to implement it…
