This is "dust" version 1 by Tatusov and Lipman, originally obtained from ftp://ncbi.nlm.nih.gov/pub/tatusov/dust/version1/src ************************************************************************ WARNING: The version of dust posted here does not interoperate properly with later versions of the licensed WU BLAST 2.0 package. It also performs extremely poorly on long sequences. Users of licensed WU BLAST 2.0 software should use the dust program included in those distributions -- not the dust that is posted here -- and should expect to obtain very good performance with it. ************************************************************************ 2000-06-05 Modified dust to preserve non-alphabetical characters in the sequence, such as - (hyphen), rather than mask them. 1998-01-28 The code posted here has had a call to exit(0) upon normal completion added, so dust's exit status can be tested for a real error. Status messages previously sent to stderr by the program that indicate normal progress have also been removed, so as to keep BLAST output clean.
