[gmx-users] Query regarding do_dssp program

[Sundari]

Dear Gromacs Users,

I have a big query regarding the "do_dssp" tool of gromacs-5.1.2.
Whenever I calculate the protein secondary structure by "gmx do_dssp" , it
shows a significant amount of beta sheet structures. But when I load the
same trajectory file in VMD for visualization of the secondary structure it
does not show any beta-sheet structures.

Please, anyone, clarify the issue.

Thank you in advance,
