This release includes new BLAST+ command-line applications.
The BLAST+ applications have a number of advantages over the older applications that include working more robustly with long sequences and a new type of masking (database masking). For details see ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/user_manual.pdf. The new applications can be downloaded from ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST These applications have been built with the NCBI C++ toolkit. Changes from the last release are listed below.
The older C toolkit applications (e.g., blastall) are still available at ftp://ftp.ncbi.nlm.nih.gov/blast/executables/release/2.2.21/
Changes from the last release are listed below.
