FASTQ extraction with `fasterq-dump` -2. Quality control with `KneadData` -3. Taxonomic profiling with `MetaPhlAn` -4. Functional profiling with `HUMAnN` (optional) +**seandavi/curatedmetagenomicsnextflow** is a bioinformatics pipeline for processing metagenomic sequencing data. The pipeline performs quality control, taxonomic profiling, and optional functional profiling following the curatedMetagenomics workflow. -## Usage +The pipeline is built using [Nextflow](https://www.nextflow.io), a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It uses Docker/Singularity containers making installation trivial and results highly reproducible. The [Nextflow DSL2](https://www.nextflow.io/docs/latest/dsl2.html) implementation of this pipeline uses one container per process which makes it much easier to maintain and update software dependencies. -Basic usage: +## Pipeline summary -```bash -nextflow run main.nf --metadata_tsv samples.tsv -``` +1. Download raw sequencing data from SRA using `fasterq-dump` (or use local FASTQ files) +2. Quality control with `FastQC` +3. Remove contaminating sequences with `KneadData` +4. Taxonomic profiling with `MetaPhlAn`: + - Generate taxonomic profiles + - Extract marker information + - Generate StrainPhlAn marker files +5. Functional profiling with `HUMAnN` (optional): + - Generate gene family abundance tables + - Generate pathway abundance and coverage tables + - Normalize tables (CPM and relative abundance) + - Split stratified/unstratified tables + +## Quick Start + +1. Install [`Nextflow`](https://www.nextflow.io/docs/latest/getstarted.html#installation) (`>=23.04.0`) + +2. Install either [`Docker`](https://docs.docker.com/engine/installation/) or [`Singularity`](https://www.sylabs.io/guides/3.0/user-guide/) (you can also use [`Podman`](https://podman.io/)) + +3. Download the pipeline and test it on a minimal dataset with a single command: + + ```bash + nextflow run seandavi/curatedmetagenomicsnextflow -profile test,docker --outdir results + ``` + + Note that some form of configuration will be needed so that Nextflow knows how to fetch the required software. This is usually done in the form of a config profile (`YOURPROFILE` in the example command above). You can chain multiple config profiles in a comma-separated string. + - The pipeline comes with config profiles called `docker`, `singularity`, `podman`, `shifter`, `charliecloud` and `conda` which instruct the pipeline to use the named tool for software management. For example, `-profile test,docker`. + - Please check [nf-core/configs](https://github.com/nf-core/configs#documentation) to see if a custom config file to run nf-core pipelines already exists for your Institute. If so, you can simply use `-profile ` in your command. This will enable either `docker` or `singularity` and set the appropriate execution settings for your local compute environment. + - If you are using `singularity`, please use the [`nf-core download`](https://nf-co.re/tools/#downloading-pipelines-for-offline-use) command to download images first, before running the pipeline. Setting the [`NXF_SINGULARITY_CACHEDIR` or `singularity.cacheDir`](https://www.nextflow.io/docs/latest/singularity.html?#singularity-docker-hub) Nextflow options enables you to store and re-use the images from a central location for future pipeline runs. + +4. Start running your own analysis! + + ```bash + nextflow run seandavi/curatedmetagenomicsnextflow --input samplesheet.tsv --outdir results -profile docker + ``` -With specific parameters: +## Documentation + +### Input Samplesheet + +You will need to create a samplesheet with information about the samples you would like to analyze before running the pipeline. Use this parameter to specify its location: ```bash -nextflow run main.nf --metadata_tsv samples.tsv --skip_humann --publish_dir results +--input '[path to samplesheet file]' ``` -## Parameters +The samplesheet should be a tab-separated file with the following columns: -### General Pipeline Parameters +- `sample_id`: Unique sample identifier +- `NCBI_accession`: SRA accession number(s), separated by semicolons for multiple runs -| Parameter | Description | Default | -| -------------- | -------------------------------------- | ------------- | -| `metadata_tsv` | Path to TSV file with sample metadata | `samples.tsv` | -| `publish_dir` | Directory to publish results | `results` | -| `store_dir` | Directory to store reference databases | `databases` | -| `cmgd_version` | Curated Metagenomic Data version | `4` | +For local FASTQ files (with `--local_input`): -### Process Control Parameters +- `sample_id`: Unique sample identifier +- `file_paths`: Path(s) to FASTQ file(s), separated by semicolons for multiple files -| Parameter | Description | Default | -| ------------- | -------------------------------- | ------- | -| `skip_humann` | Skip HUMAnN functional profiling | `false` | +Example samplesheet for SRA download: -### MetaPhlAn Parameters +``` +sample_id NCBI_accession +sample1 SRR1234567 +sample2 SRR2345678;SRR2345679 +``` -| Parameter | Description | Default | -| ----------------- | ---------------------- | -------- | -| `metaphlan_index` | MetaPhlAn index to use | `latest` | +Example samplesheet for local files: -### HUMAnN Parameters +``` +sample_id file_paths +sample1 /path/to/sample1_R1.fastq.gz;/path/to/sample1_R2.fastq.gz +sample2 /path/to/sample2_R1.fastq.gz +``` -| Parameter | Description | Default | -| ------------ | --------------------------- | ------------------ | -| `chocophlan` | ChocoPhlAn database version | `full` | -| `uniref` | UniRef database version | `uniref90_diamond` | +### Running the pipeline -## Input Format +The typical command for running the pipeline is as follows: -The `metadata_tsv` file should be a tab-separated values file with at least the following columns: -- `sample_id`: Unique sample identifier -- `NCBI_accession`: SRA accession number(s), separated by semicolons for multiple files +```bash +nextflow run seandavi/curatedmetagenomicsnextflow --input samplesheet.tsv --outdir results -profile docker +``` + +This will launch the pipeline with the `docker` configuration profile.
