Create a PNAAssay object

Create a PNAAssay object from a count matrix and a list of CellGraph objects. The expected format of the input matrix is features x cells. Optionally, a tbl_df with proximity scores and a tbl_df with information on source PXL file paths can be provided.

Usage

CreatePNAAssay(
  counts,
  cellgraphs,
  proximity = NULL,
  fs_map = NULL,
  verbose = FALSE,
  ...
)

Arguments

counts

Unnormalized data (raw counts)

cellgraphs

A named list with CellGraph objects

proximity

A tbl_df with proximity scores

fs_map

A tbl_df with information on source PXL file paths, sample IDs, and component IDs

verbose

Print messages

...

Additional arguments passed to CreateAssayObject

Value

A PNAAssay object

Examples

library(pixelatorR)
library(dplyr)

pxl_file <- minimal_pna_pxl_file()
counts <- ReadPNA_counts(pxl_file)
pna_assay <- CreatePNAAssay(
  counts = counts,
  cellgraphs = rep(list(NULL), ncol(counts)) %>%
    setNames(colnames(counts))
)
