Geographic distribution of search results
With this new feature of our main search interface, you can display the results of your sequence search as a map, with pies to display the geographical origins of the sequences. Use the 'Geography' button on the search results page. 12 June 2009

ResDB is no longer available
Due to hardware failure we have had to take down the resistance mutation database. The data can still be downloaded from the site, as tab-delimited files. The entire website can also be downloaded, so you can locally restore the database. It requires MacOS9 and Filemaker Pro. 11 June 2009

Emails to China
Some email addresses in China appear to be unreachable from our server. One example is 163.com, but there are others. A temporary solution is to use a non-Chinese email address (gmail, yahoo, etc) instead. We are trying to solve the problem. 09 June 2009

Sequence histograms
The output page of the HIV sequence Search Interface offers a new option, "Make Histogram". This option shows the distribution of your sequences across the HIV genome. At each position across the graph, the number of sequences overlapping that position is plotted as a bar. Colors within the bars represent different subtypes. The histogram allows you to see at a glance what regions and what subtypes are represented in your output. 08 April 2009

Better names for downloaded sequences
The search interface now gives the option of customizing the names of downloaded sequences. After clicking the "download sequences" button on the search results, click the "compose a label" link and choose the database fields to make up the sequence labels. This makes it possible to save some or all of the search information in the sequence names. 07 April 2009
