Our lab uses molecular, computational, and virus biology techniques to provide insights into the relationship between HIV and its human hosts in an effort to fight the AIDS pandemic.
Below is a catalog of software we’ve produced during this work to help us and others study retroviruses. Applications marked “requires login” are currently only available to lab members and our collaborators. Please email us if you’d like to learn more about them.
We provide technical and scientific support for those using our software, so please email us if you have question or are running into trouble. Our participation in a Center for AIDS Research (CFAR) provides funding for these services, so please acknowledge the CFAR in your work if you use our software.
Study divergence, diversity, informative sites, and other phylogenetic features of nucleotide and amino acid sequences using automatically constructed maximum likelihood trees
Analyze and visualize DNA methylation data in the blink of an eye
An open-source software toolkit for building databases of proviral integration sites
A platform for the collection, storage, retrieval, and analysis of experimental data for microbiology workflows and the principal data store for HIV and SIV sequencing experiments conducted in the Mullins Lab. Currently housing over 50,000 viral nucleotide sequences, together with comprehensive metadata about their creation including PCR protocols, gel images, de-identified subject clinical data, and more.
Our system for tracking, visualizing, and analyzing tissue culture experiments and qPCR screenings for assays in development
Query, download, and visualize HIV-1 integration sites from the proviral reservoir, built with ISDB
Search and display information on viral primers used in our lab
Retrieve and analyze HIV immunology data, such as ELISpot and HLA assays
Score V3 loop co-receptor motifs
BLAST multiple viral sequence databases, including public and local data, from the web
Quantitate mixed base composition in Sanger sequencing chromatograms
Determine the location of HIV integration sites in the human genome
Quantify the amplifiable viral templates under the conditions of your limiting diluation assay using a variant of the Minimum χ² (MC) method which allows specification of the probabilities of a false negative and false positive PCR

A JSON API around LANL’s sequence locator tool, providing easy programmatic access to positioning, region, and protein data
A basic API for quick, remote NCBI BLAST+ queries which returns results as XML
Two collections of record-handling tools related to biology, for use with the excellent data-slicing tools in RecordStream
A Perl library for parsing CIGAR strings (“Compact Idiosyncratic Gapped Alignment Report”), such as those used in the SAM file format, and translating coordinates to/from the reference/query.
When available, source code is generally provided via the lab’s GitHub page or the specific software’s own homepage.
