We can call individual BLAST program using the instructions given for other Unix/Linux platforms given above. We can create a query file in this directory and search it against a database. For example, the following command will search sequences in an input query file "my_sequences" against a database called "nr". The output is to be saved in my_output:
./bin/blastall -p blastn -d nr -i my_sequence -o my_output
To be able to call blast programs from any directory, we need to append the path "/User/name/blast-2.2.15/bin" to the $PATH environment variable. Check with your system administrator for technical details on this.
