Typical pipeline command:
nextflow run nf-core/chipseq -profile <docker/singularity/.../institute> --input samplesheet.csv --outdir <OUTDIR>
help message of that parameter will be printed.
or `--helpFull`.
Input/output options
--input [string] Path to comma-separated file containing information about the samples in the experiment.
--fragment_size [integer] Estimated fragment size used to extend single-end reads. [default: 200]
--seq_center [string] Sequencing center information to be added to read group of BAM files.
--read_length [integer] Read length used to calculate MACS3 genome size for peak calling if `--macs_gsize` isn't provided.
(accepted: 50, 75, 100, 150, 200)
--outdir [string] The output directory where the results will be saved. You have to use absolute paths to storage on
Cloud infrastructure.
--email [string] Email address for completion summary.
--multiqc_title [string] MultiQC report title. Printed as page header, used for filename if not otherwise specified.
Reference genome options
--genome [string] Name of iGenomes reference.
--fasta [string] Path to FASTA genome file.
--gtf [string] Path to GTF annotation file.
--gff [string] Path to GFF3 annotation file.
--bwa_index [string] Path to directory or tar.gz archive for pre-built BWA index.
--bowtie2_index [string] Path to directory or tar.gz archive for pre-built Bowtie2 index.
--chromap_index [string] Path to directory or tar.gz archive for pre-built Chromap index.
--star_index [string] Path to directory or tar.gz archive for pre-built STAR index.
--gene_bed [string] Path to BED file containing gene intervals. This will be created from the GTF file if not specified.
--macs_gsize [number] Effective genome size parameter required by MACS3.
--blacklist [string] Path to blacklist regions in BED format, used for filtering alignments.
--save_reference [boolean] If generated by the pipeline save the BWA index in the results directory.
Adapter trimming options
--clip_r1 [integer] Instructs Trim Galore to remove bp from the 5' end of read 1 (or single-end reads).
--clip_r2 [integer] Instructs Trim Galore to remove bp from the 5' end of read 2 (paired-end reads only).
--three_prime_clip_r1 [integer] Instructs Trim Galore to remove bp from the 3' end of read 1 AFTER adapter/quality trimming has been
performed.
--three_prime_clip_r2 [integer] Instructs Trim Galore to remove bp from the 3' end of read 2 AFTER adapter/quality trimming has been
performed.
--trim_nextseq [integer] Instructs Trim Galore to apply the --nextseq=X option, to trim based on quality after removing
poly-G tails.
--skip_trimming [boolean] Skip the adapter trimming step.
--save_trimmed [boolean] Save the trimmed FastQ files in the results directory.
Alignment options
--aligner [string] Specifies the alignment algorithm to use - available options are 'bwa', 'bowtie2' and 'star'.
(accepted: bwa, bowtie2, chromap, star) [default: bwa]
--keep_dups [boolean] Duplicate reads are not filtered from alignments.
--keep_multi_map [boolean] Reads mapping to multiple locations are not filtered from alignments.
--bwa_min_score [integer] Don’t output BWA MEM alignments with score lower than this parameter.
--save_align_intermeds [boolean] Save the intermediate BAM files from the alignment step.
--save_unaligned [boolean] Save unaligned sequences to the output directory (only available for Bowtie 2 and STAR.
Peak calling options
--narrow_peak [boolean] Run MACS3 in narrowPeak mode.
--broad_cutoff [number] Specifies broad cutoff value for MACS3. Only used when --narrow_peak isnt specified. [default:
0.1]
--macs_fdr [number] Minimum FDR (q-value) cutoff for peak detection, --macs_fdr and --macs_pvalue are mutually
exclusive.
--macs_pvalue [number] p-value cutoff for peak detection, --macs_fdr and --macs_pvalue are mutually exclusive. If
--macs_pvalue cutoff is set, q-value will not be calculated and reported as -1 in the final .xls
file.
--min_reps_consensus [integer] Number of biological replicates required from a given condition for a peak to contribute to a
consensus peak. [default: 1]
--save_macs_pileup [boolean] Instruct MACS3 to create bedGraph files normalised to signal per million reads.
