Yes, this is a clickbait headline, and yes, it may seem like shooting fish in a barrel to complain about crappy data in GBIF, but my point here is raise concerns about the impact of metagenomic data on GBIF, and how difficult it may be to track down the causes of errors.

Came across this paper recently: Despite QR Codes being uncool, there's something appealing about the idea of compressing a DNA barcode sequence into a small image.

I've updated the BLAST a sequence and get a tree tool described in a previous post to output additional details, such as a list of the sequences used to build the tree and some basic metadata (such as the taxon name, name of any associated host, publication, and geographic coordinates). If the sequences are geotagged, then you will also see a little map showing the localities.

For this weeks sessions of my phyloinformatics course I'm developing some phylogeny tools. The first is a simple AJAX-based BLAST tool.
