Dear all,
I am trying to use the cv command to output the value of a colvar for
each frame of a trajectory (example script below). However, the script
prints only the value corresponding to the last frame (e.g. if I load 50
frames it writes 50 times "Frame: 49; Colvar: 2.567"). Am I doing
something wrong or missing something in the script ?
I am using VMD compiled from CVS on 7th of April 2015
Thanks for any advice
Vlad
--- example script ---
mol new "topology"
mol addfile "trajectory" waitfor all
cv molid 0
cv configfile "configfile"
set numFrames [ molinfo 0 get numframes ]
for { set frame 0 } { $frame < $numFrames } { incr frame } {
animate goto $frame
cv colvar "name" update
set colvarValue [ cv colvar "name" value ]
puts "Frame: $frame; Colvar: $colvarValue"
}
