[Chimera-users] Fit MAP to MODEL

Hi Michael,

   Elaine's suggestion to use the "vop resample" command is just what 
you need.  You can also create the map from the model using the Chimera 
molmap command which is equivalent to the EMAN pdb2mrc program (I looked 
at how the pdb2mrc code defines the parameters when I implemented 
molmap).  For example

	molmap #0 5

will create a 5 Angstrom resolution map from atomic model #0.


You can also add different maps in Chimera using the "vop add" command 
and then if you want an average you can divide by the number of maps 
with the "vop scale" command.
