Some bioinformatics datasets in Weka's ARFF format.
Please see the ARFF file for further information ( iris_reloaded.zip, 92,267,000 Bytes).Īfter expanding into a directory using your jar utility (or an archive program that handles tar-archives/zip files in case of the gzip'ed tars/zip files), these datasets may be used with Weka.
