sendbs is a program that computes average nucleotide substitutions
within and between populations. The method is described in Nei and Jin
(1989, MBE 6:290-300). However, note that sendbs computes standard
errors of average nucleotide substitutions with a bootstrap method by
resampling sites, which is a different method from Nei and Jin's (1989). 
Also, sensbs construct a population tree with a neighbor-joining method.
This is a version for the SUN workstations.

Please copy files sendbs.tar.Z and sendbs.readme which is this file.
When you ftp them, use the binary mode for sendbs.tar.Z.
On your system, type 1) uncompress sendbs.tar.Z
                     2) tar xvf sendbs.tar
Then, you will have the following files.

sendbs   -- program that computes average diversity within and between
            populations
samp.seq -- sample sequence file
samp.pop -- sample population file
samp.out -- sample output file
samp.out.ps -- postscript file of a population tree
postree  -- program that generates a postscript file of a treefile
read.me  -- a brief instruction

Please read the read.me file first. It explains how to use the programs.
If you have comments or questions, please let me know.
