Update BLAST+ to v.13.0+ and set the path permanently

I have on my Linux computer the blast version v.12.0+ and would like to install the up to date version: v.13.0+.

I am having trouble with setting the PATH to this new version. Indeed, when I enter the following command in a terminal:

export PATH=/home/administrateur/ncbi-blast-2.13.0+/bin

it works great until I close my terminal.

I would like to set it permanently so that everytime I open a new terminal, the command line:

blastn -version

returns 2.13.0+ instead of 2.12.0+ ..

Could you please help me?

Many thanks..

Solution

  • For anyone wondering, the following solution worked for me:

    I printed the path of the blast directory I have downloaded (in the bin subfolder) :

    pwd -P

    and it returned:

    /home/blast/ncbi-blast-2.13.0+/bin

    I openned the bashrc file using:

    gedit ~/.bashrc

    and I added the following line at the end of this text file:

    export PATH=/home/blast/ncbi-blast-2.13.0+/bin:$PATH

    I saved this file and sourced it using:

    source ~/.bashrc

    and whenever I open a new terminal and type:

    blastn -version

    It returns:

    blastn: 2.13.0+

    Hope it helps!
