We report a method for estimating the conformational likeness between any t
wo proteins. Likeness is handled in terms of stochastic geometry, fuzzy log
ic and decision making theories. Using the method, a computer system LIKENE
SS was developed. The system does <<real time>> searching and spatial align
ment of any, PDB-available proteins. LIKENESS is accessible at URL: <<http:
