Can someone help me better understand the precision of the output coordinate
I am looking for statistically significant movement of the center of mass of
a large molecule. Using VMD's measure center command returns angstroms out
to 15 decimal places and looks quite tempting.
If the last 12 or so decimal places had meaning I could significantly reduce
the runtime for my system.
How can I determine how many of these digits are significant?
Thank you in advance.
