HIValg compares HIVdb results to those of 2 other algorithms: i. Rega Institute (rules), and ii. Agence Nationale de Recherches sur le SIDA (ANRS rules). However, it does not provide the complete HIVdb report. HIValg also allows users to interpret sequences using any algorithm created using the Algorithm Specification Interface (ASI). A detailed description of the program as well as all updates can be found in the Release Notes.
Sequences can be entered as plain text if just one sequence is entered. Sequences must be entered using the FASTA format if multiple sequences are entered. Sequences can be pasted in the text box or uploaded using the File Upload option. The upper limit is currently 1000 sequences containing 3000 nucleotides per sequence.
The program output will contain an HTML page with a navigation sidebar linking to the results for each sequence. Detailed descriptions of the HTML and spreadsheet output are explained in the Release Notes.
