Summary of de novo sequence assembly using Velvet and Oases.

The white section of the table shows the data calculated with Velvet; the grey sections indicates the data processed using Oases. Read#: total number of reads including viral sequences; Kmer: length, in base pairs, of the words being hashed to create the transcripts; Transcript #: total number of transcripts; Unigene #: total number of unigenes, where a unigene is a hypothetical gene represented by a cluster of similar transcripts thought to be isoforms in the de novo transcriptome assembly; N50: unigene length such that using equal or longer unigenes produces half the bases of the total unigenes; Unigene #>1 Kb: number of unigenes larger than 1 Kb; Max.Len.: largest unigene in each group.
