.
Define where the pipeline should find input data and save output data.
Path to a tsv file providing paths to the fastq files for each sample and the necessary metadata for the analysis.
stringThe input file includes important sample metadata and the path to the R1 and R2 fastq files, and index read file (I), if available. Please check the usage docs on information on how to create the input samplesheet.
Specify the processing mode for the pipeline. Available options are "fastq" and "assembled".ptions are: 'raw'
stringThe output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.

If set in your user config file (~/.nextflow/config) then you don't need to specify this on the command line for every run.
Path to MiAIRR-BioSample mapping
stringbcellmagic/assets/reveal/mapping_MiAIRR_BioSample_v1.3.1.tsvExperimental protocol used to generate the data
Protocol used for the V(D)J amplicon sequencing library generation.
stringAvailable protocols are:
specific_pcr_umi: RT-PCR using transcript-specific primers containing UMIs.specific_pcr: RT-PCR using transcript-specific primers.dt_5p_race_umi: 5’-RACE PCR using oligo-dT primers and template switch primers containing UMI.dt_5p_race: 5’-RACE PCR (i.e. RT is followed by a template switch (TS) step) using oligo-dT primers.
Path to fasta file containing the linker sequence, if no V-region primers were used but a linker sequence is present (e.g. 5' RACE SMARTer TAKARA protocol).
stringDefine the primer region start and how to deal with the primer alignment.
Path to a fasta file containinc the V-region primer sequences.
stringPath to a fasta file containing the C-region primer sequences.
stringStart position of V region primers (without counting the UMI barcode).
integerStart position of C region primers (without counting the UMI barcode).
integerIndicate if C region primers are in the R1 or R2 reads.
stringSpecify to match the tail-end of the sequence against the reverse complement of the primers. This also reverses the behavior of the --start argument, such that start position is relative to the tail-end of the sequence. (default: False)Maximum scoring error for the Presto MaxPrimer process for the C and/or V region primers identification.
booleanDefine how UMI barcodes should be treated.
Indicate if UMI indices are recorded in the R1 (default) or R1 fastq file.
stringThe pipeline requires UMI barcodes for identifying unique transcripts. These barcodes are typically read from an index file but sometimes can be provided merged with the start of the R1 or R2 reads. If provided in an additional index file, set the --index_file parameter, if provided merged with the R1 or R2 reads, set the --umi_position parameter to R1 or R2, respectively.
UMI barcode length in nucleotides. Set to 0 if no UMIs present.
integer-1UMI barcode start position in the index read.
integerIndicate if UMI indices are recorded in a separate index file.
booleanSet to true if UMI barcodes are to be read from a separate Illumina index fastq file. If Illumina indices and UMI barcodes are already integrated into the R1 reads, leave the default --index_file false.

Maximum error for building the sequence consensus in the pRESTO BuildConsensus step.
