本地blast

目前本地blast的版本：

下载：

wget ftp://ftp.ncbi.nlm.nih.gov/blast/executables/LATEST/

解压：

tar zxvpf ncbi-blast-2.2.31+-x64-linux.tar.gz

之后生成一个文件夹：

ncbi-blast-2.2.31+

Under bash, the following command appends the path to the new BLAST bin directory to the existing PATH setting:

export PATH=”$PATH:$HOME/ncbi-blast-2.2.31+/bin”

To manage available BLAST databases, a subdirectory named db should be created. For the example installation, the following command creates such directory under ncbi-blast-2.2.31+ directory:

mkdir ./ncbi-blast-2.2.31+/db

Similar approaches described above can be used to set the BLASTDB value under bash:

export BLASTDB=”$HOME/ncbi-blast-2.2.29+/db”
