Preferred isoschizomer ?

[ableasby at hgmp.mrc.ac.uk]

There are replacement files for rebaseextract.c and rebaseextract.acd
in the ftp://ftp.uk.embnet.org/pub/EMBOSS/patchfiles/ 
directory. By default this program will now produce an
embossre.equ file. Re-extract the withrefm file using the new
program. If you then use the -preferred option to 'restrict'
it should behave as you wish.
