With regards to the safety measures put in place by the university to mitigate the risks of the COVID-19 virus, at this time all MSI systems will remain operational and can be accessed remotely as usual. The only planned outages concern our in-person Helpdesk and tutorials. More information, as well as alternative remote support options, can be found at MSI COVID-19 Continuity Plan

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.
To run this software interactively in a Linux environment run the commands:
module load ncbi_blast
blastall -p blastp -d swissprot -i my_seq.fa -o myblast.out
This software will compare a protein sequence found in my_seq.fa against the swissprot protein database.
Local databases for BLAST searches are available in
Note: Users are strongly encouraged to use BLAST+, a new suite of BLAST tools with performance and feature improvements over the legacy BLAST applications.
