Specifically, the pipeline provides two workflows: one for processing whole-genome sequencing data, and another for processing reads from the PureTarget expansion panel offered by PacBio. This second workflow characterizes tandem repeats. Because the pipeline is designed for PacBio reads, it uses PacBio’s officially released tools. ![nf-core/pacvar metro map](docs/images/pacvar_white_background.png) Workflow Overview 1. Demultiplex reads ([`lima`](https://lima.how)) 2. Align reads ([`pbmm2`](https://github.com/PacificBiosciences/pbmm2)) 3. Sort and index alignments ([`SAMtools`](https://sourceforge.net/projects/samtools/files/samtools/)) WGS Workflow Overview 1. Choice of SNP calling routes: a. ([`deepvariant`](https://github.com/google/deepvariant)) b. ([`HaplotypeCaller`](https://gatk.broadinstitute.org/hc/en-us/articles/360037225632-HaplotypeCaller)) 2. Call SVs ([`pbsv`](https://github.com/PacificBiosciences/pbsv)) 3. Index VCF files ([`bcftools`](https://samtools.github.io/bcftools/bcftools.html)) 4. Phase SNPs, SVs and BAM files ([`hiphase`](https://github.com/PacificBiosciences/HiPhase)) Tandem Repeat Workflow Overview 1. Genotype tandem repeats - produce spanning bams and vcf ([`TRGT`](https://github.com/PacificBiosciences/trgt)) 2. Index and Sort tandem tepeat spanning bam ([`SAMtools`](https://sourceforge.net/projects/samtools/files/samtools/)) 3. Plot repeat motif plots ([`TRGT`](https://github.com/PacificBiosciences/trgt)) 4. Sort spanning VCF ([`bcftools`](https://samtools.github.io/bcftools/bcftools.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,bam,pbi CONTROL,AEG588A1_S1_L002_R1_001.bam,AEG588A1_S1_L002_R1_001.pbi ``` Note that the `.pbi` file is not required. If you choose not to include it, your input file might look like this: ```csv sample,bam,pbi CONTROL,AEG588A1_S1_L002_R1_001.bam ``` Each row represents an unaligned bam file and their associated index (optional). Now, you can run the pipeline. Below is an example ```bash nextflow run nf-core/pacvar \ -profile \ --input samplesheet.csv \ --workflow \ --barcodes barcodes.bed \ --intervals intervals.bed \ --genome \ --outdir ``` optional paramaters include: `--skip_demultiplexing`, `--skip_snp`, `--skip_sv`, `--skip_phase`. > [!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). > Please provide pipeline parameters via the CLI or Nextflow `-params-file` option.
