Filter HT-Seq output for gene subclasses

Question

[rbronste]

I was wondering about a straightforward way to filter RNA-seq datasets specifically those coming out of HT-Seq for highly expressed genes in specific subclasses, for instance all TFs (or all sequence specific binding factors) of absolute counts lets say higher than 100? Thanks!

I'd suggest that you use Ensembl BioMart for this. You could use all genes to get the gene biotype (I think) and join that with your counts to filter on.

Yes I had thought to do this however I don't believe biotype extends to such a subclass, mostly applies to protein_coding vs lncRNA vs miRNA genes etc etc
