Installing BLAST

We use the sequence search tool BLAST at several points in the course. This can be installed as follows:

Linux/macOS installation

conda install blast

Windows installation

  1. Download ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/2.7.1/ncbi-blast-2.7.1+-win64.exe with your web browser. If that FTP links does not work, try HTTP instead http://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/2.7.1/ncbi-blast-2.7.1+-win64.exe
  2. Run this installer using the defaults, it should put BLAST under C:\Program Files\NCBI\blast-2.7.1+
