[gmx-users] How to convert AMBER trajectory to Gromacs trajectory
Dear all, I have converted Amber trajectory (.mdcrd ) to Gromacs trajectory (.trr) using Amber 14 cpptraj. But Now I want to convert .trr to .xtc format. I have used this command: trjconv -s output1.pdb -f qdna-1.trr -o md_0_1.xtc -pbc none -ur compact It shows: Last frame -1 time 0.000 Setting output precision to 0.001 (nm) WARNING no output, last frame read at t=0 gcq#131: "You Fill Your Space So Sweet" (F. Apple) output1.pdb=generated by cpptraj please help me out. I am not much familiar with gromacs.I am using gromacs 4.6.7.
