# nf-core/genomeassembler data QC and preprocessing discussion

## Desired components:

### Quality Checks:

- Check file checksums
- FastQC / Nanoplot / etc
- Kraken2 / Mash
- K-mer histogram ( GenomeScope )
- K-mer consistency between files ( i.e. seeing biases between different files cf. https://kat.readthedocs.io/en/latest/walkthrough.html#checking-library-consistency )
- Data quantity check.
- Read chimerism.

### Preprocessing:

- Adapter removal
- [HiFiAdapterFilt](https://bmcgenomics.biomedcentral.com/articles/10.1186/s12864-022-08375-1)
- Subsampling
- Normalization (e.g. for Whole genome amplified)
- Read filtering
- from List (txt file)
- from mapping (take ID's from bam)
