ultra

Align long-read RNA sequencing fastq files using uLTRA

usage

nexus run --nf-workflow alignment_ultra.nf \
    -c nextflow.config \
    -w work/ \
    --samples_tsv_file samples.tsv \
    --output_dir results/ \
    --reference_genome_fasta_file /path/to/file.fasta \
    --reference_genes_gtf_file /path/to/file.gtf \
    --params_ultra_index "--disable_infer" \
    --params_ultra "--isoseq"

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).
