Command Line Interface¶

This page shows the MicroHapulator command line interface: how inputs and settings are specified for each subcommand.

NOTE: The MicroHapulator CLI is under Semantic Versioning. In brief, this means that every stable version of the MicroHapulator software is assigned a version number, and that any changes to the software's behavior or interface require the software version number to be updated in prescribed and predictable ways.

End-to-end analysis workflow¶

`mhpl8r pipe`¶

Perform a complete end-to-end microhap analysis pipeline

usage: mhpl8r pipe [-h] [-w D] [-n] [-t T] [--copy-input]
                   markerrefr markerdefn seqpath samples [samples ...]

Positional Arguments¶

markerrefr: path to a FASTA file containing marker reference sequences
markerdefn: path to a TSV file containing marker definitions
seqpath: path to a directory containing FASTQ files
samples: list of sample names or path to .txt file containing sample names

Named Arguments¶

-w, --workdir: pipeline working directory; default is current directory
-n, --dryrun: do not execute the workflow, but display what would have been done
-t, --threads: process each batch using T threads; by default, one thread per available core is used
--copy-input: copy input files to working directory; by default, input files are symlinked

Haplotype calling¶

`mhpl8r type`¶

Perform haplotype calling

usage: mhpl8r type [-h] [-o FILE] [-b B] [-m M] tsv bam

Positional Arguments¶

tsv: path of a TSV file containing marker metadata, specifically the offset of each SNP for every marker in the panel
bam: path of a BAM file containing NGS reads aligned to marker reference sequences and sorted

Named Arguments¶

-o, --out: write output to FILE; by default, output is written to the terminal (standard output)
-b, --base-qual: minimum base quality (PHRED score) to be considered reliable for haplotype calling; by default B=10, corresponding to Q10, i.e., 90% probability that the base call is correct
-m, --max-depth: maximum permitted read depth; by default M=1000000

`mhpl8r filter`¶

Apply static and/or dynamic thresholds to distinguish true and false haplotypes. Thresholds are applied to the haplotype read counts of a raw typing result. Static integer thresholds are commonly used as detection thresholds, below which any haplotype count is considered noise. Dynamic thresholds are commonly used as analytical thresholds and represent a percentage of the total read count at the marker, after any haplotypes failing a static threshold are discarded.

usage: mhpl8r filter [-h] [-o FILE] [-s ST] [-d DT] [-c FILE] result

Positional Arguments¶

result: MicroHapulator typing result in JSON format

Named Arguments¶

-o, --out: write output to FILE; by default, output is written to the terminal (standard output)
-s, --static: global fixed read count threshold
-d, --dynamic: global percentage of total read count; e.g. use --dynamic=0.02 to apply a 2% analytical threshold
-c, --config: CSV file specifying marker-specific thresholds to override global thresholds; three required columns: 'Marker' for the marker name; 'Static' and 'Dynamic' for marker-specific thresholds

Analysis, QA/QC, and interpretation¶

`mhpl8r locbalance`¶

Plot interlocus balance in the terminal and/or a high-resolution graphic. Also normalize read counts and perform a chi-square goodness-of-fit test assuming uniform read coverage across markers. The reported chi-square statistic measures the extent of imbalance, and can be compared among samples sequenced using the same panel: the minimum value of 0 represents perfectly uniform coverage, while the maximum value of D occurs when all reads map to a single marker (D represents the degrees of freedom, or the number of markers minus 1).

usage: mhpl8r locbalance [-h] [-c FILE] [-D] [-q] [--figure FILE]
                         [--figsize W H] [--dpi DPI] [-t T]
