|---|---|
| Description: | This package provides methods and object classes for parsing FastQC reports and output summaries from other NGS tools into R. As well as parsing files, multiple plotting methods have been implemented for visualising the parsed data. Plots can be generated as static ggplot objects or interactive plotly objects. |

The function takes the supplied object and returns the theoretical GC content distribution. Using a fixed read length essentially leads to a discrete distribution so the bins argument is used to define the number of bins returned. This defaults to 101 for 0 to 100% inclusive.
The returned values are obtained by interpolating the values obtained during sampling. This avoids returned distributions with gaps and jumps as would be obtained setting readLengths at values not in multiples of 100.

This object class is the main object required for generating plots
and tables. Instantiation will first check for a .json file with the correct
data structure, and will then parse all the data into R as a FastpData
object. Fastp modules are contained as individual slots, which can be viewed
using slotNames. Sub-modules are also contained within many larger modules
with modules being based on the sections within a fastp html report
Individual modules can be returned using the function getModule()
and specifying which module/sub-module is required. See getModule() for
more details.

An object of class TheoreticalGC of length 1.
The object is defined with the S4 class TheoreticalGC.
Species for which information is available can be found using
the command gcAvail(gcTheoretical) and selecting the appropriate type.
Metadata is accessible using mData(gcTheoretical).
All GC content was calculated using code from https://github.com/mikelove/fastqcTheoreticalGC using BSgenome packages. This provides a default set of GC content data for common organisms generated using 100bp reads/fragments and 1e6 reads.

Imports one or more log files as output by tools such as:
bowtie, bowtie2, featureCounts, Hisat2, STAR, salmon
picard MarkDuplicates, cutadapt, flagstat, macs2Callpeak,
Adapter Removal, trimmomatic, rnaseqcMetrics, quast or busco.
autoDetect can be used to detect the log type by parsing the file.
The featureCounts log file corresponds to the counts.out.summary,
not the main counts.out file.
Whilst most log files return a single tibble, some are more complex with multiple modules.
adapterRemoval can return one of four modules (which = 1:4),.
When calling by name, the possible values are sequences, settings,
statistics or distribution.
Partial matching is implemented.
cutadapt can return one of five modules (which = 1:5).
When calling by name the possible modules are summary, adapter1, adapter2,
adapter3 or overview.
Note that adapter2/3 may be missing from these files depending on the nature
of your data.
If cutadapt log files are obtained using report=minimal, all supplied
log files must be of this format and no modules can be returned.
duplicationMetrics will return either the metrics of histogram.
These can be requested by setting which as 1 or 2, or naming either module.
A tibble.
Column names are broadly similar to the text in supplied files,
but have been modified for easier handling under R naming conventions.

This extracts the Adapter_Content module from the supplied object and generates a ggplot2 object, with a set of minimal defaults. The output of this function can be further modified using the standard ggplot2 methods.
When x is a single or FastqcData object line plots will always be
drawn for all adapters.
Otherwise, users can select line plots or heatmaps.

When acting on a FastqcDataList, this defaults to a heatmap
using the mean Per_base_sequence_quality score. A set of plots which
replicate those obtained through a standard FastQC html report can be
obtained by setting plotType = "boxplot", which uses facet_wrap
to provide the layout as a single ggplot object.
When acting an a FastqcData object, this replicates the
Per base sequence quality plots from FastQC with no faceting.
For large datasets, subsetting by R1 or R2 reads may be helpful.
An interactive plot can be obtained by setting usePlotly = TRUE.

This extracts the Sequence_Duplication_Levels from the supplied object and generates a ggplot2 object, with a set of minimal defaults. For multiple reports, this defaults to a heatmap with block sizes proportional to the percentage of reads belonging to that duplication category.
If setting usePlotly = FALSE, the output of this function can be
further modified using standard ggplot2 syntax. If setting
usePlotly = TRUE an interactive plotly object will be produced.

This carries out PCA on a single FastQC module and plots the output using either ggplot or plotly. Current modules for PCA are Per_base_sequence_quality, Per_sequence_quality_scores, Per_sequence_GC_content, Per_base_sequence_content, and Sequence_Length_Distribution.
If a factor is provided in the groups argument, this will be applied to the
plotting colours and ellipses will be drawn using these groups.
Only the labels will be plotted using geom_text()

Makes plots for GC_Content. When applied to a single FastqcData object a simple line plot will be drawn, with Theoretical GC content overlaid if desired.
When applied to multiple FastQC reports, the density at each GC content bin
can be shown as a heatmap by setting theoreticalGC = FALSE. By
default the difference in observed and expected theoretical GC is shown.
Species and genome/transcriptome should also be set if utilising the
theoretical GC content.
As an alternative to a heatmap, a series of overlaid distributions can be
shown by setting plotType = "line".
Can produce a static ggplot2 object or an interactive plotly object.

As the Kmer Content module present in FastQC reports is relatively uninformative, and omitted by default in later versions of FastQC, these are rudimentary plots.
Plots for FastqcData objects replicate those contained in a FastQC
report, whilst the heatmap generated from FastqcDataList objects
simply show the location and abundance of over-represented Kmers.

This extracts the N_Content from the supplied object and generates a ggplot2 object, with a set of minimal defaults. The output of this function can be further modified using the standard ggplot2 methods.
When x is a single FastqcData object line plots will always be drawn
for all Ns.
Otherwise, users can select line plots or heatmaps.

Percentages are obtained by simply summing those within a report. Any possible double counting by FastQC is ignored for the purposes of a simple approximation.
Plots generated from a FastqcData object will show the top n
sequences grouped by their predicted source & coloured by whether the
individual sequence would cause a WARN/FAIL.
Plots generated from a FastqcDataList group sequences by predicted
source and summarise as a percentage of the total reads.

Draw a barplot of read totals using the standard ggplot2 syntax.
The raw data from readTotals() can otherwise be used to manually
create a plot.
Duplication levels are based on the value shown on FASTQC reports at the
top of the DeDuplicatedTotals plot, which is known to be inaccurate.
As it still gives a good guide as to sequence diversity it is included as
the default. This can be turned off by setting duplicated = FALSE.
For FastpDataList objects, duplication statistics are not part of the default module containing ReadTotals. However, the status of reads and the reason for being retained or filtered is, and as such these are shown instead of duplication statistics.

Per base sequence content (%A, %T, %G, %C), is shown as four overlaid
heatmap colours when plotting from multiple reports. The individual line
plots are able to be generated by setting plotType = "line", and the
layout is determined by facet_wrap from ggplot2.
Individual line plots are also generated when plotting from a single
FastqcData object.
If setting usePlotly = TRUE for a large number of reports, the plot
can be slow to render.
An alternative may be to produce a plot of residuals for each base, produced
by taking the position-specific mean for each base.

This extracts the Sequence Length Distribution from the supplied object and generates a ggplot2 object, with a set of minimal defaults. The output of this function can be further modified using the standard ggplot2 methods.
A cdf plot can also be generated to provide guidance for minimum
read length in some NGS workflows, by setting plotType = "cdf".
If all libraries have reads of identical lengths, these plots may be less
informative.
An alternative interactive plot is available by setting the argument
usePlotly = TRUE.

pwf is an object of class PwfCols supplied with the package
and used as the default colouring.
Colours correspond approximately to PASS, WARN and FAIL from the FASTQC
reports, with the additional colour (MAX) included to indicate an extreme
FAIL.
In order, these colours in the default vector are green
(rgb(0, 0.8, 0)), yellow (rgb(0.9, 0.9, 0.2)), red
(rgb(0.8, 0.2, 0.2)) and white (rgb(1, 1, 1))

Define the PwfCols class and associated methods
This is an object of with four colours in components named PASS, WARN, FAIL and MAX. Used to indicate these categories as defined on the standard plots from fastqc.
An S4 object of class PwfCols
PASSA vector of length 1, defining the colour for PASS in rgb format. Defaults to rgb(0, 0.8, 0)
WARNA vector of length 1, defining the colour for WARN in rgb format. Defaults to rgb(0.9, 0.9, 0.2)
FAILA vector of length 1, defining the colour for FAIL in rgb format. Defaults to rgb(0.8, 0.2, 0.2)
MAXA vector of length 1, defining the colour for an extreme FAIL or NA in rgb format. Defaults to rgb(1, 1, 1)

This function prepares a useful summary of all over-represented sequences as reported by either fastp or FastQC
A tibble
Tibble columns will vary between Fastp*, FastqcDataList and FastqcData objects. Calling this function on list-type objects will attempt to summarise the presence each over-represented sequence across all files.
In particular, FastqcData objects will provide the requested summary statistics across all sequences within a file
