usage

nexus run --nf-workflow quantification_kallisto-lr.nf \
    -c nextflow.config \
    -w work/ \
    --samples_tsv_file samples.tsv \
    --output_dir results/ \
    --reference_transcripts_fasta_file /path/to/file.fasta \
    --reference_genes_gtf_file /path/to/file.gtf \
    --params_kallisto_index "-k 63" \

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’, ‘fastq_file’.
--reference_transcripts_fasta_file Reference transcripts FASTA file.
--reference_genes_gtf_file Reference genes GTF file.
--output_dir Directory to which output files will be copied.
--params_kallisto_index Kallisto index parameters (default: ‘“-k 63”’).
--params_kallisto_bus Kallisto bus parameters (default: ‘“-x bulk –threshold 0.8”’). Note that the parameters need to be wrapped in quotes and a space at the end of the string is necessary.
--params_bustools_sort Bustools sort parameters (default: ‘““’). Note that the parameters need to be wrapped in quotes and a space at the end of the string is necessary.
--params_bustools_count Bustools count parameters (default: ‘“–cm -m”’). Note that the parameters need to be wrapped in quotes and a space at the end of the string is necessary.
--params_kallisto_quanttcc Kallisto quant-tcc parameters (default: ‘“-P PacBio –matrix-to-files”’). Note that the parameters need to be wrapped in quotes and a space at the end of the string is necessary.
