Hello Everyone I have performed a md simulation if protein in water for 10ns and frames were obtained after every 10ps. I wanted to visualize the.gro and trajectory file in VMD, without water, so I prepared an index file containing protein only. Using editcon i removed water from md.gro as well but I loaded the files in VMD, 1000 time frames are loaded but I cannot see any change in structure or per frame conformation. The protein is still. I am not clear what to do. I tried keeping water in .trr and then in .gro and repeated steps but no results. When I use original .trr and .gro, only then i visualize the change in structure. Please help me
You can't load coordinate and trajectory files with different numbers of atoms. If you strip the waters from the starting .gro file, you must also do this for the trajectory (that's what eats up all the memory in VMD, anyway).
