Comma-separated string, specifies feature metadata columns to be used for exploratory analysis, platform-specific

This parameter allows you to supply your own feature annotations. These can often be automatically derived from the GTF used upstream for RNA-seq, or from the Bioconductor annotation package (for affy arrays).

Where a GTF file is supplied, which feature type to use

Where a GTF file is supplied, which field should go first in the converted output table

Of which assays to compute the log2. Not necessary for maxquant data as this is controlled by the pipeline.

Column of the sample sheet containing the Affymetrix CEL file name

logical value. If TRUE, then background correct using RMA background correction.

integer value indicating which RMA background to use

logical value. If TRUE, then works on the PM matrix in place as much as possible, good for large datasets.

Used to specify the name of an alternative cdf package. If set to NULL, then the usual cdf package based on Affymetrix’ mappings will be used.

logical value. If TRUE, a matrix of probe annotations will be derived.

should the spots marked as ‘MASKS’ set to NA?

should the spots marked as ‘OUTLIERS’ set to NA?

if TRUE, then overrides what is in rm.mask and rm.oultiers.

Prefix of the column names of the MaxQuant proteingroups table in which the intensity values are saved; the prefix has to be followed by the sample names that are also found in the samplesheet. Default: ‘LFQ intensity ’; take care to also consider trailing whitespace between prefix and samplenames.

Normalization function to use on the MaxQuant intensities.

Which method to use for plotting sample distributions of the MaxQuant intensities; one of ‘violin’, ‘dist’, ‘box’.

Should a loess line be added to the plot of mean-variance relationship of the conditions? Default: true.

Valid R palette name

Number of decimals to round the MaxQuant intensities to; default: -1 (will not round).

Minimum abundance value

Minimum observations that must pass the threshold to retain the row/ feature (e.g. gene).

A minimum proportion of observations, given as a number between 0 and 1, that must pass the threshold. Overrides minimum_samples

An optional grouping variable to be used to calculate a min_samples value

Clustering method used in dendrogram creation

Correlation method used in dendrogram creation

Number of features selected before certain exploratory analyses

Length of the whiskers in boxplots as multiple of IQR. Defaults to 1.5.

Threshold on MAD score for outlier identification

How should the main grouping variable be selected? ‘auto_pca’, ‘contrasts’, or a valid column name from the observations table.

Valid R palette name

The suffix associated tabular differential results tables

The feature identifier column in differential results tables

The fold change column in differential results tables

The p value column in differential results tables

The q value column in differential results tables.

Minimum fold change used to calculate differential feature numbers

Maximum p value used to calculate differential feature numbers

Maximum q value used to calculate differential feature numbers

Where a features file (GTF) has been provided, what attributed to use to name features

Indicate whether or not fold changes are on the log scale (default is to assume they are)

Valid R palette name
