I'm using dbFetch from EBI in a project. I construct URLs from the format
to retrieve sequences, e.g.:
Accession numbers need to be of the format 1 letter + 5 numerals OR 2 letters + 6 numerals,
so I added a test with the clearly bogus accession code
To my surprise, the URL
returned a valid response, namely the sequence for "Avocado sunblotch viroid, complete genome" with accession number
- Why does the accession number
XXfetches the record with accession number
- Is this a bug in the dbFetch software or incorrectly submitted data?
- If so, should this be reported somewhere?
Interestingly, I couldn't find any other invalid code that returns something when it shouldn't - only 'XX'. Also, https://www.ebi.ac.uk/Tools/dbfetch/emblfetch?id=J02020 also returns the correct entry, so there are (at least) two pointers to this entry. Definitely looks like an error, but I'm not sure who the best person to report it to is.
It's a rather old entry, which could mean that perhaps once XX really was its accession. Check for example this. Keep us updated..
