set sel1 [atomselect top {index 29953}]
  set sel2 [atomselect top {index 29957}]
  set coor1 [$sel1 get {x y z}]
  set coor2 [$sel2 get {x y z}]
  set d [vctdist $coor1 $coor2]
  puts $d
  
  When I run it, it says:
  "vecsub: non-numeric in first argument"
  
  aren't $coor1 and $coor2 vectors here? What should I do? Thanks
