Dear NAMD users,
Good afternoon,I have trouble in collective variable, when i am collecting
Z positions in Colvars. I found the distance collected is from main
atomnumbers to ref atomnumbers. But what I want to collect is absolute Z
positions (like reference atom is (0,0,0)), Do you know how to set this? I
try to use dummyatom as reference atom, it can't recognize it. and if I
make anychange, does it affect harmonic constant part?
Thank you for your time.
here is my colvars file.
refPositions (0.0, 0.0, 0.0)}
axis ( 0.0, 0.0, 1.0 )
forceConstant 1 # in kcal/mol/A^2
centers -1.0 # go from 25 Angstrom RMSD...
