[gmx-users] from coarse-grained to all atoms

[Francesco Carbone]

Good afternoon,
I have some trajectories of coarse-graned (CG) simulations obtained using
the UNRES force field (not implemented in GROMACS).

I'd like to apply the analysis protocol that I generally use for gromacs
trajectories also to these one, but because there are no native tools,  I
was thinking about doing something like:

1) convert each structure of the CG trajectory to all atoms (using their
tools)
2) use trjcat to generate a gromacs trajectory (.xtc)
3) use gromac tools on it.

May this approach work or it would generate unreliable results?

Best,

Francesco
