Hi Dr. Kohlmeyer,
I am afraid I'm still a bit confused--all of these variants fail and I
can't figure out the correct syntax from the manual.
vmd > volmap ils $sel -minmax {{-68 -77 -80} {68 77 80}} -dx output.dx
vmd > volmap ils $sel -minmax {{-68 -77 -80} {68 77 80}} -allframes
-combine pmf -dx output.dx -dihomo -probe1 -0.12 1.70 -bond 1.12 -conf 50
-cutoff 12 -subres 2
vmd > volmap ils $sel -minmax {{-68 -77 -80} {68 77 80}} -allframes
-combine pmf -dx output.dx -dihomo -probe1 -0.12 1.70 -bond 1.12 -conf 50
-cutoff 12 -subres 2
The error is always:
expected integer but got "atomselect6"volmap: molecule specified for ouput
is invalid. (-mol)
Thanks for responding; I really appreciate it.
