I am wondering if rnaSPAdes represents a convenient assembler for RNA viruses (from metagenomes or metatranscriptomes). As far as I know, rnaSPAdes cannot be set in any other kmer than 55mer. On the other hand, metaSPAdes can be set in several (also smaller) kmers. Is this feature making the latter a more convenient assembler for extracting RNA viruses from datasets?
Let me know what you think please. Thanks!
