Hi,

The coordinates in the PDB file of an atom are:

75.146 114.983 -86.817

using

for {set i $first} {$i < $last} {incr i} {
    set sel3 [atomselect top "resid $i and name C1'"]
puts [$sel3 get {x y z}]
}

they are returned as:

{75.14600372314453 114.98300170898438 -86.81700134277344}

Question:

Maybe I am missing some understanding of something here:

How does VMD/TCL script get the higher precision??

Any comments anyone ??
