R6 Class for loading, visualising and analysing barcode information

R6 Class for loading, visualising and analysing barcode information

Super class

floundeR::FloundeR -> MultiplexSet

Active bindings

enumerate

prepares a simple 2D Angenieux enumeration of the provided dataset for quick visualisation of the dataset.

Methods

Public methods

Inherited methods

Method new()

Initialise a new instance of the R6 Class MultiplexSet

Usage

MultiplexSet$new(seqsum = NA, barcoding_summary_file = NA)

Arguments

seqsum

a tibble of sequencing summary information

barcoding_summary_file

is a file.path to the corresponding barcoding_summary file that should be merged with the seqsum content.


Method as_tibble()

Export the imported dataset(s) as a tibble

This object consumes a sequencing summary file (and optionally the corresponding barcoding_summary file) and creates an object in memory that can be explored, sliced and filtered. This method dumps out the in-memory object for further exploration and development.

Usage

MultiplexSet$as_tibble()

Returns

A tibble representation of the starting dataset


Method read_length_bins()

bin the sequences in seqsum content into bins of sequence length

The nanopore sequencing run is expected to return a collection of sequences that vary in their length distributions; this variance is a function of the sequencing library prepared, the starting DNA etc. This method is used to bin reads into uniform bins & assess the distribution of sequence lengths.

Usage

MultiplexSet$read_length_bins(
  qfilt = TRUE,
  normalised = TRUE,
  cumulative = FALSE,
  bins = 20,
  outliers = 0.025
)

Arguments

qfilt

  • specifies how the quality information should be filtered

  • at the moment this only defines whether reporting is based on PASS or FAIL reads; would make more sense to have filtered by PASS / ALL?

normalised

  • should the sequence collection be reported to normalise for the number of sequence bases sequenced or the number of sequence reads - TRUE by default to normalise for sequenced bases.

cumulative

defines whether cumulative sequence bases (reads) are reported per bin (FALSE by default).

bins

the number of sequence bins that should be prepared (20 by default)

outliers

defines the number of outliers (0.025 = 2.5%) that are excluded from the longest reads to prepare a richer distribution visulation - the plots can be bothered by the long tail of mini-whales.

Returns

Angenieux 2D graph object


Method quality_bins()

bin the sequences in seqsum content into bins of quality

The nanopore sequencing run is expected to return a collection of sequences that vary in their quality distributions; this variance is a function of the sequencing library prepared, the starting DNA etc. This method is used to bin reads into uniform quality bins to assess the overall quality of the run and to identify potential issues

Usage

MultiplexSet$quality_bins(bins = 20, outliers = 0)

Arguments

bins

the number of sequence bins that should be prepared (20 by default)

outliers

defines the number of outliers (0 = 0%) that are excluded from the reads - should probably be deprecated for simplicity?

Returns

Angenieux 2D graph object


Method sequencingset()

Prepare a SequencingSet object from a given barcode

This method is used to subset the sequencing_summary information to focus on a single barcode for more detailed analysis.

Usage

MultiplexSet$sequencingset(barcode)

Arguments

barcode

the barcode that should be reported

Returns

SequencingSet object containing information on barcode of interest.


Method temporalset()

Prepare a TemporalSet object from a given barcode

This method is used to subset the SequencingSummary information to focus on a single barcode for a more detailed analysis of content.

Usage

MultiplexSet$temporalset(barcode)

Arguments

barcode

the barcode that should be reported

Returns

TemporalSet object containing information on barcode of interest.


Method clone()

The objects of this class are cloneable with this method.

Usage

MultiplexSet$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
