Introduction

BLAST^® (Basic Local Alignment Search Tool) is a set of similarity search programs designed to explore all of the available sequence databases regardless of whether the query is protein or DNA. For a detailed overview of BLAST, please refer to http://www.ncbi.nlm.nih.gov/blast/blast_overview.shtml

Information Technology Services Centre has implemented a local web-based version of the NCBI (National Center for Biotechnology Information) WWWBLAST server together with the NCBI databases in the Memory-Intensive Computing Server (Orpin). And all sequence databases in this local server will be updated from the NCBI server every two weeks.

In general, sequence searching through the local server is faster than through the server at NCBI. Additionally, if you have already built your own sequence database and you want to integrate it into our local server for searching by the BLAST programs, please contact us at https://helpdesk.itsc.cuhk.edu.hk/group/bioinformatics-help .
