Assembly can be done via `flye` or `hifiasm`, polishing can be carried out with `medaka` (ONT), or `pilon` (requires short-reads), and scaffolding can be done using `LINKS`, `Longstitch`, or `RagTag` (if a reference is available). Quality control includes `BUSCO`, `QUAST` and `merqury` (requires short-reads). Currently, this pipeline does not implement phasing of polyploid genomes or HiC scaffolding. ## 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,ontreads,hifireads,ref_fasta,ref_gff,shortread_F,shortread_R,paired sampleName,ontreads.fa.gz,hifireads.fa.gz,assembly.fasta.gz,reference.fasta,reference.gff,short_F1.fastq,short_F2.fastq,true ``` Each row represents one genome to be assembled. `sample` should contain the name of the sample, `ontreads` should contain a path to ONT reads (fastq.gz), `hifireads` a path to HiFi reads (fastq.gz), `ref_fasta` and `ref_gff` contain reference genome fasta and annotations. `shortread_F` and `shortread_R` contain paths to short-read data, `paired` indicates if short-reads are paired. Columns can be omitted if they contain no data, with the exception of `shortread_R`, which needs to be present if `shortread_F` is there, even if it is empty. Now, you can run the pipeline using: ```bash nextflow run nf-core/genomeassembler \ -profile \ --input samplesheet.csv \ --outdir ``` > [!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/genomeassembler/usage) and the [parameter documentation](https://nf-co.re/genomeassembler/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/genomeassembler/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/genomeassembler/output). ## Credits nf-core/genomeassembler was originally written by [Niklas Schandry](https://github.com/nschan), of the Faculty of Biology of the Ludwig-Maximilians University (LMU) in Munich, Germany.
