Hello friends,
I want to compute the lipid tilt angles of a membrane simulation in vmd
from its dcd trajectory, but I got the following error while executing
the membplugin of vmd. Kindly let me know how to fix this error:
Error:
vecsub: two vectors don't have the same size
vecsub: two vectors don't have the same size
