Sequence similarity searches (e.g. BLAST) made easy.

Project description

PyPI version

seqsearch version 2.2.1

seqsearch is a python package for dealing sequence similarity searches (e.g. BLAST on DNA sequences) and automation.

It has many convenience methods that can automatically launch several types of search algorithms, as well as quick installation of sequence reference databases.


Since seqsearch is written in python, it is compatible with all operating systems: Linux, macOS and Windows. The only prerequisite is python3 (which is often installed by default) along with the pip3 package manager.

To check if you have python3 installed, type the following on your terminal:

$ python3 -V

If you do not have python3 installed, please refer to the section obtaining python3.

To check you have pip3 installed, type the following on your terminal:

$ pip3 -V

If you do not have pip3 installed, please refer to the section obtaining pip3.


To install the seqsearch package, simply type the following commands on your terminal:

$ pip3 install --user seqsearch

Alternatively, if you want to install it for all users of the system:

$ sudo pip3 install seqsearch


Bellow are some examples to illustrate the various ways there are to use this package.


You can parallelize BLAST searches by splitting the input into several files. It's easier to chop-up the input, because database chopping requires message passing across the nodes like mpiblast does (when and if it works).

Input chopping is fine as long as the database to search against fits in the RAM of the nodes. If the input is small and the database is large you can always switch them one for the other (in most cases).
