Enclosed is the package for local alignment: (see: Chao, K.-M. (1994) Computing all suboptimal alignments in linear space. Combinatorial Pattern Matching '94, Lecture Notes in Computer Science, 807, 31-42.) This package contains the following files: README Makefile AC.h sub.h AC.c sub.driver.c sub.c (for constructing the DAG that contains all suboptimal alignments) pat_AC.c (for finding a path in DAG that maximizes the total pattern score) To make a compiled version under UNIX, type "make".
