DAJIN2 0.3.1b4

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

From PyPI:

pip install DAJIN2

From Bioconda:

conda install -c bioconda DAJIN2

Usage

Single Sample Analysis

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

DAJIN2 <-s|--sample> <-c|--control> <-a|--allele> <-n|--name> [-g|--genome] [-t|--threads] [-h|--help] [-v|--version]

options:
  -s, --sample              Path to a sample FASTQ file
  -c, --control             Path to a control FASTQ file
  -a, --allele              Path to a FASTA file
  -n, --name                Output directory name
  -g, --genome (Optional)   Reference genome ID (e.g hg38, mm39) [default: '']
  -t, --threads (Optional)  Number of threads [default: 1]
  -h, --help                show this help message and exit
  -v, --version             show the 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 <-f|--file> [-t|--threads] [-h]

options:
  -f, --file                Path to a CSV or Excel file
  -t, --threads (Optional)  Number of threads [default: 1]
  -h, --help                Show this help message and exit

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
