DAJIN2 0.3.1

One-step genotyping tools for targeted long-read sequencing

DAJIN2 is a genotyping software designed for organisms that have undergone genome editing, utilizing nanopore sequencing technology.

The name DAJIN is inspired by the term 一網打尽 (Ichimou DAJIN or Yīwǎng Dǎjìn), which signifies capturing everything in a single net.

Disclaimer

DAJIN2 is still in the development phase.
Basic tests covering point mutations, deletions, and insertion designs have been conducted.
If you encounter any bugs or issues, please report them via Issues.

Installation

To install DAJIN2, simply run the following command:

pip install DAJIN2

Usage

Single Sample Analysis

DAJIN2 allows for the analysis of single samples (one sample vs one control).

DAJIN2 [-h] [-s SAMPLE] [-c CONTROL] [-a ALLELE] [-n NAME] [-g GENOME] [-t THREADS] [-v]

options:
  -h, --help            show this help message and exit
  -s SAMPLE, --sample SAMPLE
                        Full path to a sample FASTQ file
  -c CONTROL, --control CONTROL
                        Full path to a control FASTQ file
  -a ALLELE, --allele ALLELE
                        Full path to a FASTA file
  -n NAME, --name NAME  Output directory name
  -g GENOME, --genome GENOME
                        Reference genome ID (e.g hg38, mm10) [default: '']
  -t THREADS, --threads THREADS
                        Number of threads [default: 1]
  -v, --version         show program's version number and exit

Example

# Donwload the example dataset
wget https://github.com/akikuno/DAJIN2/raw/main/examples/example-single.tar.gz
tar -xf example-single.tar.gz

# Run DAJIN2
DAJIN2 \
    --name stx2-deletion \
    --sample example-single/sample.fq.gz \
    --control example-single/control.fq.gz \
    --allele example-single/design.fa \
    --genome mm39 \
    --threads 10

Batch Processing

DAJIN2 can also handle multiple FASTQ files using the batch subcommand.

DAJIN2 batch [-h] -f FILE [-t THREADS]

options:
  -h, --help            Show this help message and exit
  -f FILE, --file FILE  CSV or Excel file
  -t THREADS, --threads THREADS
                        Number of threads [default: 1]

Example

# Donwload the example dataset
wget https://github.com/akikuno/DAJIN2/raw/main/examples/example-batch.tar.gz
tar -xf example-batch.tar.gz

# Run DAJIN2
DAJIN2 batch --file example-batch/batch.csv --threads 3
