HIVbase can search through your sequences for genetic motif, drug resistance mutation,
or any user-defined attribute in seconds. Mining your HIV-1 data has never been
easier. Simply identify the fields you want returned in your query, and select the
conditions. For example, if you wanted to identify sequences from T-cell tropic
viruses, you could create a query that returns back the sequence name and set the
condition to be where the V3 loop contained a charge >4. Running that query will
return all of the sequences in your database that match those conditions.
