Comment: C: Many paralogous genes in GO enrichment results
... Even if you don't have the sequences, the GFF file should contain start and end positions so you could cluster things that overlap. Hard to tell what's possible or not without knowing what kind of data you have access to. ...

Comment: C: Many paralogous genes in GO enrichment results
... Based on what you describe, it would seem that the outcome is biased by redundancy, i.e. the same gene is represented by multiple IDs. This could be the case if you're working with transcript IDs. Try working with gene IDs instead. ...

Answer: A: How to map ChEMBL ID to Entrez Gene?
... ChEMBL targets are primarily associated with Uniprot accessions so you'll probably need to do it in two steps. The first is to retrieve the Uniprot accession number, the second to convert Uniprot accession to Entrez gene ID. For the first step, you have a few options: - You can retrieve Uniprot ...

Comment: C: Versioning of Blast DB and Reproducible Research
... > Sequence names and IDs don't change That's true only to some extent. Names used to change quite often, maybe less frequently now but can be ambiguous. IDs may be more stable but would still need a database version to be completely unambiguous. Some databases consider that a minor change does ...

Comment: C: How to perform alignment of nucleotide sequence containing ambiguous bases
... Like blastn, other software tend to treat ambiguities as mismatches which I think is the conservative way of doing it. Also have a look at exonerate, I don't remember exactly how it treats ambiguity codes but as a last resort you could pass it a custom substitution matrix that includes ambiguity cod ...
