The new BLAST results are now the default view


As you may know,  we have been offering a new BLAST results (Figure 1) as a test page since April.  In response to your positive reception and after incorporating many improvements that you suggested, we made the new results the default today,  August 1, 2019.

You will still be able to access to the traditional results for a several months. This will provide you additional time if you need it to adjust your workflows or teaching materials to the new display.

Thank you for the feedback on the new results.  We made several improvements to address issues or concerns that you pointed out.  You also told us about 17 additional features you would like us to add. We are working on incorporating these into the page and welcome additional suggestions.  Please let us know what you think.

Troubleshooting GenBank Submissions: Annotating the Coding Region (CDS)


This article is intended for GenBank data submitters with a basic knowledge of BLAST who submit sequence data from protein-coding genes.

One of the most common problems when submitting DNA or RNA sequence data from protein-coding genes to GenBank is failing to add information about the coding region (often abbreviated as CDS) or incorrectly defining the CDS. Incomplete or incorrect CDS information will prevent you from having accession numbers assigned to your submission data set, but there is a procedure that will help you troubleshoot any problems with the CDS feature annotation: doing a BLAST analysis with your sequences before you submit your data.

Here’s how to use nucleotide BLAST (blastn) and the formatting options menu to analyze, interpret and troubleshoot your submissions:

1. To start the BLAST analysis, go to the BLAST homepage and select “nucleotide blast”.
