I have generated md_0_1_noPBC.xtc and other related file using gromacs 5.0 . but I am stuck as md_0_1_noPBC.xtc is not opening with vmd . How to do further analysis?
As noted above, you have to load a coordinate file first. An .xtc is just a binary containing box vectors and coordinates. VMD has no knowledge of what the atoms are or how to connect them, so you have to start with a coordinate file and load the trajectory as data for that coordinate file. Do some VMD tutorials; this is covered in the simple examples.
