(1992) "Aligning two sequences within a specified diagonal band," CABIOS, 8, 481-487.) This package contains the following files: README Makefile g_band.driver.c g_band.c (for global alignments) l_band.driver.c l_band.c (for local alignments) To make a compiled version, type "make". Command examples: (Match score is 1) g_band data/short1 data/short2 -15 15 -1.0 6.0 0.2 > out0 g_band data/human.1500 data/rabbit.1500 -50 50 -1.0 6.0 0.2 > out1 g_band data/liverwort.seq data/liv.revcomp.seq -100 100 -1.0 6.0 0.2 > out2
