Respected Sir/Ma’am,  
I am Sankar Maity, a Ph.D scholar at the National Institute of Technology Rourkela, India. I have .nc or .dcd trajectory files using AMBER and would like to perform further analysis (GROMACS-LS and the MDStress library enable the calculation of local stress fields from molecular dynamics simulations). Could anyone please suggest me on how to analyze my trajectory files (.nc or .dcd) using GROMACS?

Thank You  
Sankar Maity
