In a previous post, I described having problems using maketxdbfromGFF, which led to a txdb with missing tx_id attributes
Now I found that:
txdb <- makeTxDbFromBiomart(dataset = "mochrogaster_gene_ensembl")
produces a txdb without any errors. This is much better, but I'd like to change the 'Ensembl' seqlevels to the 'NCBI' seqlevels. Is there any easy way to do this?
