- # NCBI Standalone Blast
+2) NCBI Standalone Blast
       - Download and install BLAST 2.8.1+ installer for your machine which is available from NCBI at [Blast Executables](https://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/).
       - Set up a searchable database for the Blast search of the host genome or transcriptome (e.g., from the NCBI, [Human Genome Sequences](https://www.ncbi.nlm.nih.gov/genome/guide/human/)) using the command (for host genome or transcriptome in FASTA format, here named hostdb): makeblastdb -in hostdb.fna -dbtype nucl -parse_seqids  -out hostdb. 
       - Add the created database to the system path, and re-direct the blastn query from the code (python) to find blast hits to the directory with the host database.
