Option 1: Install clustalw in your path so that you (and the emma program) can
run it from the commandline. The directory where you installed EMBOSS is one
possible place you can put it.
Option 2: Emma will look for a variable EMBOSS_CLUSTALW (an environment
variable or a variable defined inemboss.defaults or .embossrc) that has the
full path for clustalw.
Now ... we should document this ... and perhaps update the emma documentation
which looks rather old and has too much old clustal information in it.
Hope this helps,
