An overview of sequence pairwise comparison and identity matrix visualization into Geminivirus Data Warehouse..
Initially, the input genome sequence (or gene sequence) is inserted in the search form and submitted for local alignment using BLAST algorithm. Then, an output file of the alignment is generated, which contains a list of the best hits. The sequences are pre-selected by the users and the comparison between sequence queries is automatically calculated by the SDT tool included into BegomoDW. Finally, the pairwise matrix and graphics of density are displayed. In addition, this file can be downloaded and edited by any editor software.
