[Chimera-users] Distance and Angles

[Thomas Goddard]

Hi Andy,

   To show a distance between atoms select the two atoms and use menu 
entry Tools / Structure Measurements / Distances and press the Create 
button.  You can show distances for multiple pairs of atoms.

   Not sure what you mean by the angle between two density map surfaces. 
  The surfaces intersect in many places making different angles.  You 
could place 3 markers with Volume tracer and measure the angle made by 
those 3 markers using the Angles/Torsions tab of the Structure 
Measurement dialog.
