RefSeq: NCBI Reference Sequence Database A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein. Using RefSeq. Refseq annotation files are available for many genomes from NCBI. There are other sources depending on the organism/genome build version. Try UCSC, Ensembl, and the like. Before using with tools, make sure that the reference genome that the annotation is based on is . But the mapping software that we will be using, STAR, does not like the GFF format that NCBI uses for annotation. We could get the GFF from NCBI and convert it to a format that STAR likes, but it is easier to look elsewhere to see if we can find a GTF formatted file that STAR likes.

Question: Converter for GFF file downloaded from NCBI to GTF. GTF is basically GFF, but as the name suggests, is more specific to the features it describes and must have the same nomenclature for the gene IDs and transcripts (unlike GFF which is flexible in this respect). RefSeq: NCBI Reference Sequence Database A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein. Using RefSeq. I have a fasta file containing thousands of gene sequences. I want to create a GTF annotation file that describes the locations of these genes, their exons etc. Refseq annotation files are available for many genomes from NCBI. There are other sources depending on the organism/genome build version. Try UCSC, Ensembl, and the like.
