Project Status: Sunset Notice

[!IMPORTANT] This repository (Bamboo) is no longer under active development or maintenance.

For the latest features, improved performance, and a more user-friendly experience in long-read quality control and error profiling, we strongly recommend all users transition to our new tool: Rosa.

Why Switch to Rosa?

• Expanded Functionality: Provides more comprehensive QC metrics and detailed descriptions to assist with result interpretation.
• Enhanced Usability: Features a streamlined installation process and numerous bug fixes for a smoother experience.
• Active Support: Our team is highly responsive; please reach out by opening a GitHub issue.

Bamboo

a tool for quality control and error profiling of long-read sequencing data.

Installation

# Install samtools and Minimap2
conda create -n bamboo_env samtools minimap2

# Check the latest version of Bamboo
BAMBOO_VERSION=$(curl -s https://api.github.com/repos/CycloneSEQ-Bioinformatics/Bamboo/releases/latest | grep "tag_name" | awk -F'"' '{print $4}' | sed 's/^v//')
echo $BAMBOO_VERSION 

# Download Bamboo executable
wget https://github.com/CycloneSEQ-Bioinformatics/Bamboo/releases/download/v$BAMBOO_VERSION/bamboo-$BAMBOO_VERSION.tar.gz

# Unzip
tar xvzf bamboo-$BAMBOO_VERSION.tar.gz

# Update file permission to allow bamboo to be executed.
cd bamboo-$BAMBOO_VERSION
chmod +x bamboo

# Test bamboo installation and show help message.
./bamboo --help

Example Usage

bamboo -i input1.fastq input2.fastq -o output_dir --sample_size 50000 --seed 123
bamboo -b input.bam -r reference.fasta -o output_dir --realign
bamboo --sequence_path Bamboo-main/test/data/ecoli_hifi.reads.fastq.gz --reference_path Bamboo-main/test/data/ecoli.reference.fasta.gz -o test_bamboo_fastqtobam2 --sample_size 10000

Command-line arguments

usage: bamboo [-h] [-b BAM_PATH] [-r REFERENCE_PATH] [--realign] [--minimap2_path MINIMAP2_PATH] [--minimap2_args MINIMAP2_ARGS] [--samtools_path SAMTOOLS_PATH]
              [--align_all] [-i SEQUENCE_PATH [SEQUENCE_PATH ...]] [-o OUTPUT_DIR] [-t THREADS] [--sample_size SAMPLE_SIZE] [--seed SEED] [--keep-intermediates]

Bamboo v0.2.0: a tool for quality control and error profiling of long-read sequencing data.

optional arguments:
  -h, --help            show this help message and exit

Sequence analyses:
  Arguments for sequence analyses.

  -i SEQUENCE_PATH [SEQUENCE_PATH ...], --sequence_path SEQUENCE_PATH [SEQUENCE_PATH ...]
                        Path to the input FASTQ file. If multiple input files are supplied, they will be concatenated before analyses. (default: None)

Alignment analyses:
  Arguments for alignment analyses.

  -b BAM_PATH, --bam_path BAM_PATH
                        Path to the input BAM file. (default: None)
  -r REFERENCE_PATH, --reference_path REFERENCE_PATH
                        Path to the reference FASTA file. (default: None)
  --realign             Re-align sampled reads using Minimap2. Use this option if the input BAM file does not contain x/= CIGAR operations. (default: False)
  --minimap2_path MINIMAP2_PATH
                        Path to Minimap2 executable. (default: minimap2)
  --minimap2_args MINIMAP2_ARGS
                        Command line arguments for Minimap2 (default: -ax map-ont --eqx --secondary=no -t 8)
  --samtools_path SAMTOOLS_PATH
                        Path to samtools executable. (default: samtools)
  --align_all           When `--bam_path` is not specified, perform alignment for all input reads (rather than just the sampled reads) to the reference genome.
                        Aligning all reads will improve accuracy of sequencing coverage analyses, but can take a considerable amount of time. (default: False)

General arguments:
  General input/output arguments.

  -o OUTPUT_DIR, --output_dir OUTPUT_DIR
                        Directory to save output figures and reports. (default: bamboo_report)
  -t THREADS, --threads THREADS
  --sample_size SAMPLE_SIZE
                        The number of reads to be analyzed. Use --sample_size -1 to disable random sampling and analyze all reads in the input data. (default:
                        100000)
  --seed SEED           Random seed for sampling. (default: 42)
  --keep-intermediates  Do not remove intermediate data files generated in the analyses. (default: False)
