Dear NAMD users,
Good afternoon, Is that possible to tracking four pair atom distances
independently at same time and apply harmonic constant? I am trying to use
four part of distance { }. But I found in the colvars.traj file, it only
provides one column distance tracking results. Could some help me with this?
Thank you for your time!

colvar {
  name length
  outputAppliedForce off

  distance {
    group1 {
      atomNumbers 11530
    }
    group2 {
      atomNumbers 10888
    }
    }
  distance {
  group1 {
      atomNumbers 5266
    }
    group2 {
      atomNumbers 4624
    }
    }
  distance {
  group1 {
      atomNumbers 11794
    }
    group2 {
      atomNumbers 17152
    }
  }
}
