whatshap

Haplotype long-read DNA sequencing BAM files using Whatshap

usage

nexus run --nf-workflow haplotyping_whatshap.nf \
    -c nextflow.config \
    -w work/ \
    --samples_tsv_file samples.tsv \
    --output_dir results/ \
    --reference_genome_fasta_file /path/to/file.fasta \
    --params_whatshap "--ignore-read-groups --tag-supplementary --skip-missing-contigs --output-threads 4"

Note

Nextflow config files are available here. Use the config file that matches your installed nexus version (e.g. nexus_v0.2.0_nextflow_slurm.config).

parameters

parameter	description
--samples_tsv_file	TSV file with the following columns: ‘sample_id’, ‘bam_file’, ‘bam_bai_file’, ‘phased_small_variants_vcf_file’, ‘phased_small_variants_vcf_tbi_file’.
--output_dir	Directory to which output files will be copied.
--reference_genome_fasta_file	Reference genome FASTA file (should not be gzipped).
--params_whatshap	Whatshap parameters (default: ‘“–ignore-read-groups –tag-supplementary –skip-missing-contigs –output-threads 4”’). Note that the parameters need to be wrapped in quotes.
