It allows for in-parallel taxonomic identification of reads or taxonomic abundance estimation with multiple classification and profiling tools against multiple databases, and produces standardised output tables for facilitating results comparison between different tools and databases. ## Pipeline summary ![](docs/images/taxprofiler_tube.png) 1. Read QC ([`FastQC`](https://www.bioinformatics.babraham.ac.uk/projects/fastqc/) or [`falco`](https://github.com/smithlabcode/falco) as an alternative option) 2. Performs optional read pre-processing - Adapter clipping and merging (short-read: [fastp](https://github.com/OpenGene/fastp), [AdapterRemoval2](https://github.com/MikkelSchubert/adapterremoval); long-read: [porechop](https://github.com/rrwick/Porechop), [Porechop_ABI](https://github.com/bonsai-team/Porechop_ABI)) - Low complexity and quality filtering (short-read: [bbduk](https://jgi.doe.gov/data-and-tools/software-tools/bbtools/), [PRINSEQ++](https://github.com/Adrian-Cantu/PRINSEQ-plus-plus); long-read: [Filtlong](https://github.com/rrwick/Filtlong)), [Nanoq](https://github.com/esteinig/nanoq) - Host-read removal (short-read: [BowTie2](http://bowtie-bio.sourceforge.net/bowtie2/); long-read: [Minimap2](https://github.com/lh3/minimap2)) - Run merging 3. Supports statistics metagenome coverage estimation ([Nonpareil](https://nonpareil.readthedocs.io/en/latest/)) and for host-read removal ([Samtools](http://www.htslib.org/)) 4. Performs taxonomic classification and/or profiling using one or more of: - [Kraken2](https://ccb.jhu.edu/software/kraken2/) - [MetaPhlAn](https://huttenhower.sph.harvard.edu/metaphlan/) - [MALT](https://uni-tuebingen.de/fakultaeten/mathematisch-naturwissenschaftliche-fakultaet/fachbereiche/informatik/lehrstuehle/algorithms-in-bioinformatics/software/malt/) - [DIAMOND](https://github.com/bbuchfink/diamond) - [Centrifuge](https://ccb.jhu.edu/software/centrifuge/) - [Kaiju](https://kaiju.binf.ku.dk/) - [mOTUs](https://motu-tool.org/) - [KrakenUniq](https://github.com/fbreitwieser/krakenuniq) - [KMCP](https://github.com/shenwei356/kmcp) - [ganon](https://pirovc.github.io/ganon/) 5. Perform optional post-processing with: - [bracken](https://ccb.jhu.edu/software/bracken/) 6. Standardises output tables ([`Taxpasta`](https://taxpasta.readthedocs.io)) 7. Present QC for raw reads ([`MultiQC`](http://multiqc.info/)) 8. Plotting Kraken2, Centrifuge, Kaiju and MALT results ([`Krona`](https://hpc.nih.gov/apps/kronatools.html)) ## Usage > [!NOTE] > If you are new to Nextflow and nf-core, please refer to [this page](https://nf-co.re/docs/usage/installation) on how to set-up Nextflow. Make sure to [test your setup](https://nf-co.re/docs/usage/introduction#how-to-run-a-pipeline) with `-profile test` before running the workflow on actual data. First, prepare a samplesheet with your input data that looks as follows: `samplesheet.csv`: ```csv sample,run_accession,instrument_platform,fastq_1,fastq_2,fasta 2612,run1,ILLUMINA,2612_run1_R1.fq.gz,, 2612,run2,ILLUMINA,2612_run2_R1.fq.gz,, 2612,run3,ILLUMINA,2612_run3_R1.fq.gz,2612_run3_R2.fq.gz, ``` Each row represents a fastq file (single-end), a pair of fastq files (paired end), or a fasta (with long reads). Additionally, you will need a database sheet that looks as follows: `databases.csv`: ```csv tool,db_name,db_params,db_path kraken2,db2,--quick,///kraken2/testdb-kraken2.tar.gz metaphlan,db1,,///metaphlan/metaphlan_database/ ``` That includes directories or `.tar.gz` archives containing databases for the tools you wish to run the pipeline against. Now, you can run the pipeline using: ```bash nextflow run nf-core/taxprofiler \ -profile \ --input samplesheet.csv \ --databases databases.csv \ --outdir \ --run_kraken2 --run_metaphlan ``` > [!WARNING] > Please provide pipeline parameters via the CLI or Nextflow `-params-file` option. Custom config files including those provided by the `-c` Nextflow option can be used to provide any configuration _**except for parameters**_; see [docs](https://nf-co.re/docs/usage/getting_started/configuration#custom-configuration-files). For more details and further functionality, please refer to the [usage documentation](https://nf-co.re/taxprofiler/usage) and the [parameter documentation](https://nf-co.re/taxprofiler/parameters). ## Pipeline output To see the results of an example test run with a full size dataset refer to the [results](https://nf-co.re/taxprofiler/results) tab on the nf-core website pipeline page. For more details about the output files and reports, please refer to the [output documentation](https://nf-co.re/taxprofiler/output). ## Credits nf-core/taxprofiler was originally written by James A.
