This is the default Kpax database folder. It is possible to have 
multiple databases (SCOP, CATH, your own set of structures...),
and each will be created as a subdirectory of this folder. When
you search a database using e.g.

   kpax -db=cath query.pdb

this means Kpax will look for a subfolder called

   ${KPAX_DATABASE}/cath_kpax/

and it will compare query.pdb to all of the structures in that folder.
In other words, the database structure behaves as if you have 
defined an environment variable using

   KPAX_DATABASE=${KPAX_ROOT}/kpax_database/

You can change the top level database folder by defining the variable
KPAX_DATABASE accordingly.
