Dear David,

Thank you for your reply. I used ambpdb to convert .prmtop and inpcrd to
.pdb, and visualize .pdb using vmd.

I can see the entire waterbox by selecting resname WAT using VMD. The
protein is in the water box.

Thanks again!

Wu

First of all it seems like you told VMD that it is reading an Amber Parm7
topology and Amber coordinates (.crd). However, you need to tell cmd that
it is reading coordinates WITH periodic box--I think that will get rid of
the yarn ball. Otherwise, because it's a periodic box, and a VERY
generous
buffer volume, I think you're just seeing a large and loose protein in the
best representation VMD can make--it probably is surrounded by water when
you consider periodic boundaries, but you will see that only if you center
the box on an appropriate residue of the protein.
