Did you know...


isomesh creates a mesh isosurface object from a map object.


isomesh name, map, level [,(selection) [,buffer [,state [,carve ]]]] 
  • name = the name for the new mesh isosurface object.
  • map = the name of the map object to use for computing the mesh.
  • level = the contour level (in sigma units)
  • selection = an atom selection about which to display the mesh with an additional "buffer" (if provided).
  • state = the state into which the object should be loaded (default=1) (set state=0 to append new mesh as a new state)
  • carve = a radius about each atom in the selection for which to include density. If "carve" is not provided, then the whole brick is displayed.


# load the map
load mymap.xplor, themap
# view the isomesh map
isomesh themapobject, themap, 2.0, site, carve=1.6
Output from the 2nd example

<source lang="python">

  1. create fake map for demo

load $TUT/1hpv.pdb

  1. set b and q for all atoms

alter all, b=10 alter all, q=1
