Hello,

I am new at this and I am working with the constraints algorithms used in a
MD simulation. I would like to now how they work, what type of coordinates
they use and also to identify some variables.

For that, I am trying to do a simulation with a toy input system, like
methane or ethane but I am having some troubles: I started with a methane
PDB file and pdb2gmx but I got errors, I tried with a ethane simulation
using the files: ethane.gro, ethane.mdp and ethane.top but I also got
errors, ...

I know it is a very open-question but, could you help me? What would you
recommend me? Do you have a toy input system?


You can find a large number of common molecules (both coordinates and topologies) on http://virtualchemistry.org/.
