Create probe coordinates

Description

Create probe coordinates

Usage

createProbeCoords(nrows, ncols,
                  meta_nrows = 1, meta_ncols = 1,
                  meta_padding = 5)

Arguments

nrows Number of rows per sub-array
ncols Number of columns per sub-array
meta_nrows Number of sub-arrays per row
meta_ncols Number of sub-arrays per column
meta_padding Padding between sub-arrays

Value

A data.frame of columns:

row row position within the sub-array
col column position within the sub-array
metarow sub-array index in the row
metacol sub-array index in the column
x fictitious x coordinate
y fictitious y coordinate

Examples

# array with 10,000 probes
one_plex <- createProbeCoords(100, 100)
plot(y ~ x, data=one_plex, pch=".",
     main = "array 1x10k")

# 4x2.5k array
four_plex <- createProbeCoords(50, 50, 2, 2)
plot(y ~ x, data=four_plex, pch=".",
     main = "array 4x2.5k")
