BioWeka 0.5.0 released

The BioWeka 0.5.0 release provides a new filter called AddLastAttributeFrom. This filter can be used to add an attribute, e.g. the class annotation, from an external dataset to the current dataset.

In addition, the new BioWeka version includes two minor bug fixes:

• the relation name of a filtered data set does not contain anymore any white spaces or the pipe operator. This change has become necessary because the BlastClassifier uses the relation name as the name for the BLAST database and BLAST uses the database name as the file name for the database. However, Windows permitsforbids the pipe operator within file names.
• the iprscan.xsl stylesheet declares the sequence.name attribute as of type nominal instead of string. This is a workaround for a well-known problem of Weka with sparse instances and string attributes.
