hi, I want to calculate the distance of the center of mass between two selected atom sets.
I try
coor distance sele segid 1 end sele segid 2 end. but it gives all distance between these two atom sets. I only need the center of mass of these two selections. anybody can give me a hint?

thanks in advance.
Use COOR AXIS MASS with the appropriate double atom selection; see corman.doc
