Hi,

I think there is something like that described in this paper:
F. M. D. Vellieux "An enveloped cross rotation function"
J. Appl. Cryst. (1995). 28, 834-836
If I remember correctly, the calculations where done using x-plor scripts.

Objet : [ccp4bb] Rotation search using the Patterson in a non-spherical neighbourhood of the origin

Dear everyone,
is any of the currently available
molecular replacement programs capable of accepting a
description of an ellipsoid (rather than the radius of a sphere)
to define the portion of the Patterson around the origin to be
used in a Molecular
Replacement rotation search? Our search model is an elongated
object and we are searching in a cell with a=205 b=100 c=21
Angstrom ... ;-)

Ciao

Pietro
