[Chimera-users] Contouring ED Maps

Also regarding contouring ED maps: we have ccp4 maps that are fine in  
coot, but as soon as you display them in chimera they are sharply  
chopped in one direction, as if there is any problem with a border.  
Any suggestion, the effect it's particularly bad for a surface  
representation, but it's also obvious when you display it as a mesh.

Thank you!
