Description Usage Arguments Value
Create a SingleCellExperiment object and perform normalization. The same as conclus::normalizeCountMatrix.
1 2 3 4 | normaliseCountMatrix(countMatrix, species, method = "default",
sizes = c(20, 40, 60, 80, 100), rowData = NULL, colData = NULL,
alreadyCellFiltered = FALSE, runQuickCluster = TRUE,
databaseDir = system.file("extdata", package = "conclus"))
|
countMatrix |
a matrix with non-normalised gene expression. |
species |
either 'mmu' or 'human'. |
method |
a method of clustering: available option is "default" using scran and scater. |
sizes |
a vector of size factors from scran::computeSumFactors() function. |
rowData |
a data frame with information about genes |
colData |
a data frame with information about cells |
alreadyCellFiltered |
if TRUE, cells quality check and filtering will not be applied. However, the function may delete some cells if they have negative size factors after scran::computeSumFactors. |
runQuickCluster |
if scran::quickCluster() function must be applied. Usually, it allows to improve normalization for medium-size count matrices. However, it is not recommended for datasets with less than 200 cells and may take too long for datasets with more than 10000 cells. |
databaseDir |
a path to annotation database provided with CONCLUS called "Mmus_gene_database_secretedMol.tsv" (only for MusMusculus 'mmu'). The function will work also without the database but slower because it will retrieve genes info from biomaRt. |
A SingleCellExperiment object with normalized gene expression, colData, and rowData.
