Welcome to the BtToxin_scanner website! BtToxin_scanner is a web-based Bt toxin mining tool which integrated BLAST, HMM (Hidden Markov Model) and SVM (Supporting Vector Machine) prediction modules. If you have massive genomic data of Bacillus thuringiensis, and you want to extract Bt toxins from those huge data, then you are at the right place. You can submit your fasta format sequence file (< 16 MB). After a few seconds later (Depends on your data size, 1.0 MB/min for protein sequences and ORFs, and 1.8 MB/min for nucleotide sequences), you will get what you want. If you have any questions about how to use our website, just go to the Manual section. A new high-throughput tool for mining Bt toxins can be found here.
