I have the v70 Ensembl BLAST code installed on a machine. BioPerl 1.2.3 is linked in as the "bioperl-live" directory, but 1.6.9 is also installed into the standard Perl library. I believe this is causing conflicts. Which is the recommended version? -- Ken Youens-Clark kclark at cshl.edu Ware Lab/CSHL/USDA-ARS
