This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up.
Grateful (and slightly humbled) to be part of this. Thanks Alberto!

Under the hood it's the same BLAST executable and databases provided by NCBI, with a replica of the NIH's interface - providing an alternative to the US gov service that's less congested, faster & more reliable
