Arguments

conos

Conos object

cdl

list Optional list of raw matrices (so that gene merging doesn't have to be redone) (default=NULL)

metadata

list Optional list of (named) metadata factors (default=NULL)

filename

string Name of the *.bin file to seralize for the pagoda2 application if save=TRUE (default='conos_app.bin')

save

boolean Save serialized *bin file specified in filename (default=TRUE)

n.cores

integer Number of cores (default=1)

n.odgenes

numeric Number of top overdispersed genes to use (dfault=3e3). From pagoda2::basicP2proc().

nPcs

numeric Number of PCs to use (default=100). From pagoda2::basicP2proc().

k

numeric Default number of neighbors to use in kNN graph (default=30). From pagoda2::basicP2proc().

perplexity

numeric Perplexity to use in generating tSNE and largeVis embeddings (default=50). From pagoda2::basicP2proc().

log.scale

boolean Whether to use log scale normalization (default=TRUE). From pagoda2::basicP2proc().

trim

numeric Number of cells to trim in winsorization (default=10). From pagoda2::basicP2proc().

keep.genes

optional set of genes to keep from being filtered out (even at low counts) (default=NULL). From pagoda2::basicP2proc().

min.cells.per.gene

numeric Minimal number of cells required for gene to be kept (unless listed in keep.genes) (default=0). From pagoda2::basicP2proc().

min.transcripts.per.cell

numeric Minimumal number of molecules/reads for a cell to be admitted (default=100). From pagoda2::basicP2proc().

get.largevis

boolean Whether to caluclate largeVis embedding (default=TRUE). From pagoda2::basicP2proc().

get.tsne

boolean Whether to calculate tSNE embedding (default=TRUE). From pagoda2::basicP2proc().

make.geneknn

boolean Whether pre-calculate gene kNN (for gene search) (default=TRUE). From pagoda2::basicP2proc().

go.env

GO environment for the organism of interest (default=NULL)

cell.subset

string Cells to subset with the conos embedding conos$embedding. If NULL, uses all cells via rownames(conos$embedding) (default=NULL)

max.cells

numeric Limit to the cells that are included in the conos. If Inf, there is no limit (default=Inf)

additional.embeddings

list Additional embeddings to add to conos for the pagoda2 app (default=NULL)

test.pathway.overdispersion

boolean Find all IDs using GO category against either org.Hs.eg.db ('hs') or org.Mm.eg.db ('mm') (default=FALSE

organism

string Organism of interest, either 'hs' (Homo sapiens) or 'mm' (Mus musculus, i.e. mouse) (default=NULL). Only used if test.pathway.overdispersion is TRUE. If NULL and test.pathway.overdispersion=TRUE, then 'hs' is used.

return.details

boolean If TRUE, return list of p2 application, pagoda2 object, list of raw matrices, and cell names. If FALSE, simply return pagoda2 app object. (default=FALSE)

Value

pagoda2 app object
