GRAPPA is available as a gzipped tar file containing all source files needed to compile an executable version. Documentation for this early release is minimal (there is a README file and some online help). GRAPPA changes quickly, so be sure to grab the latest release.

GRAPPA was featured in Access, the magazine of the NCSA/Alliance in Vol. 14 (1) (Spring 2001). It is discussed at some length in

Its linear-time computation of inversion distance is presented in The improvements due to better bounding and new search ordering (the layered method) are discussed in while the improvements achieved through the use of true inversion medians are documented in which also contains references to the works of A. Caprara and of A. Siepel, whose codes for the computation of true inversion medians are included in this release.

The latest release is

GRAPPA-2.0
from October 1, 2004.

Previous releases (1.6 and 1.03) are obsolete.
