Hi, FYI, when I feed the coordinates in '.binpos' format, which I generated after loading the same '.crd' file to VMD, could able to do the job. What I infer from this is that the VMD molfile, for reading AMBER '.crd' trajectories, has made for reading AMBER 7 '.crd' formatted trajectories which can not able to read latest ones.
