HIFI-SE

Project description

HIFI-barcode-SE400

The BGISEQ-500 platform has launched a new test sequencing kits capable of single-end 400 bp sequencing (SE400), which offers a simple and reliable way to achieve DNA barcodes efficiently. In this study, we explored the potential of the BGISEQ-500 SE400 sequencing in DNA barcode reference construction, meanwhile provided an updated HIFI-Barcode software package that can generate COI barcode assemblies using HTS reads of length >= 400 bp.

Installation

System requirement and dependencies

Operating system: HIFI-SE is designed to run on most platforms, including UNIX, Linux and MacOS/X. Microsoft Windows. We have tested on Linux and on MacOS/X, because these are the machines we develop on. HIFI-SE is written in python language, and a version 3.5 or higher is required.

Dependencies:

Install

  1. I only deploy my latest version on github, so you can clone this repository to your local computer. However, it would not solve package dependencies, thus you need to install biopython and bold_identification before using HIFI-SE software.(NOTE: pip is a link from pip3)

    git clone https://github.com/comery/HIFI-barcode-SE400.git
    pip install biopython
    pip install bold_identification  
    
  2. Installation by pip is recommended because it will solve package dependencies automatically, including biopython and bold_identification packages.

    pip install HIFI-SE

Usage (latest)

python3 HIFI-SE.py

or

./HIFI-SE.py
usage: HIFI-SE [-h] [-v]
               {all,filter,assign,assembly,polish,bold_identification} ...

Description

    An automatic pipeline for HIFI-SE400 project, including filtering
    raw reads, assigning reads to samples, assembly HIFI barcodes
    (COI sequences), polished assemblies, and do tax identification.
