Dear Amber Users,

I am simulation a protein-ligand complex using Amber16 and using vmd-1.9.3
for visualization of trajectories.

I am following the method described in one of the Amber tutorials for using
vmd for visualizing the trajectories, but getting the following error:

Info) Using plugin crdbox for coordinates from file
Problem reading CRD file
Info) Finished with coordinate file

First I loaded the prmtop file in vmd andgot the following output in the

vmd > Info) Using plugin parm7 for structure file
Info) Analyzing structure ...
Info) Atoms: 94950
Info) Bonds: 95134
Info) Angles: 0 Dihedrals: 0 Impropers: 0 Cross-terms: 0
Info) Bondtypes: 0 Angletypes: 0 Dihedraltypes: 0 Impropertypes: 0
Info) Residues: 28298
Info) Waters: 27448
Info) Segments: 1
Info) Fragments: 27456 Protein: 8 Nucleic: 0

Then I loaded the mdcrd file with the filetype "Amber coordinates with
periodic box".

Can anyone please help me in resolving the err: "Problem reading CRD file" ?

With regards
