nf-core/differentialabundance

A string to identify results in the output directory

A string identifying the technology used to produce the data

Path to comma-separated file containing information about the samples in the experiment.

A CSV file describing sample contrasts

The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.

Type of abundance measure used, platform-dependent

TSV-format abundance matrix

Alternative to matrix: a compressed CEL files archive such as often found in GEO

Column in the samples sheet to be used as the primary sample identifier

Type of observation

Column in the sample sheet to be used as the display identifier for observations

Feature ID attribute in the GTF file (e.g. the gene_id field)

Feature name attribute in the GTF file (e.g. the gene symbol field)

Type of feature we have, often ‘gene’

When set, use the control features in scaling/ normalisation

A text file listing technical features (e.g. spikes)

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).

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.

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)

Number of cores

blind parameter for rlog() and/ or vst()

nsub parameter passed to vst()

passed to lmFit(), positive integer giving the number of times each distinct probe is printed on each array.

passed to lmFit(), positive integer giving the spacing between duplicate occurrences of the same probe, spacing=1 for consecutive rows.

Sample sheet column to be used to derive a vector or factor specifying a blocking variable on the arrays

passed to lmFit(), the inter-duplicate or inter-technical replicate correlation

passed to lmFit(), the fitting method

passed to eBayes(), a numeric value between 0 and 1, assumed proportion of genes which are differentially expressed

passed to eBayes(), logical, should an intensity-dependent trend be allowed for the prior variance?

passed to eBayes(), logical, should the estimation of df.prior and var.prior be robustified against outlier sample variances?

passed to eBayes, comma separated string of two values, assumed lower and upper limits for the standard deviation of log2-fold-changes for differentially expressed genes

passed to eBayes, comma separated string of length 1 or 2, giving left and right tail proportions of x to Winsorize. Used only when robust=TRUE.

passed to topTable(), minimum absolute log2-fold-change required

passed to topTable(), logical, should confidence 95% intervals be output for logFC? Alternatively, can take a numeric value between zero and one specifying the confidence level required.

passed to topTable(), method used to adjust the p-values for multiple testing.

cutoff value for adjusted p-values. Only genes with lower p-values are listed.
