[gmx-users] Trajectory files in vmd

[Aditi Borkar]

Dear Rui,

Thanx for the explanation. I did not know that VMD only calculates the
secondary structure fort he first frame only. Is there an option to
calculate the secondary structure (say in New cartoon representation)
of all the frames in the trajectory?
