These can be obtained at NCBI's ftp site:

	anonymous FTP to

For the blosum tables, look in the directory /repository/blocks/unix/blosum
For the PAM matricies, there is a program called "pam" which will generate the
tables for you (get pam.c and compile).  This can be found in
/pub/blast/1.4d/explode/blastapp (there are also some PAM tables already
generated; look in the matrix subdirectory).
