Example

The example below reads frames from a fictitious molecular dynamics trajectory of two files until the last frame is reached:

read trajectory
  
  asci=true
  input=pti_00_50.crd
  input=pti_50_100.crd
  begin=1000 skip=1000 stop=100000

end

while ($status # "COMPLETE") loop traj

  read trajectory next end

end loop traj
