Description
I'm trying to annotate cell types of visium 10x data using the annotateCellTypesGSEA function. This is a minimal script to reproduce the error
library(STdeconvolve)
library(SpatialExperiment)
se <- SpatialExperiment::read10xVisium(samples = "./116_run",
type = "sparse",
data = "filtered")
se
# this is the genes x barcode sparse count matrix
cd <- se@assays@data@listData$counts
pos <- SpatialExperiment::spatialCoords(se)
# change column names to x and y
# for this dataset, we will visualize barcodes using "pxl_col_in_fullres" = "y" coordinates, and "pxl_row_in_fullres" = "x" coordinates
colnames(pos) <- c("y", "x")
counts <- cleanCounts(cd, min.lib.size = 100, min.reads = 10)
corpus <- restrictCorpus(counts, removeAbove=1.0, removeBelow = 0.05, nTopOD = 1000)
#ldas <- fitLDA(t(as.matrix(corpus)), Ks = seq(2, 15, by = 1),
ldas <- fitLDA(t(as.matrix(corpus)), Ks = 10,
perc.rare.thresh = 0.05,
plot=TRUE,
verbose=TRUE)
optLDA <- optimalModel(models = ldas, opt = "min")
results <- getBetaTheta(optLDA, perc.filt = 0.05, betaScale = 1000)
deconProp <- results$theta
deconGexp <- results$beta
gset <- list(
test_type1 = c("FLG", "FLG2"),
test_type2 = c("KTR25", "KTR71")
)
celltype_annotations <- annotateCellTypesGSEA(beta = results$beta, gset = gset, qval = 0.05)
The error itself is
initial: [1e+02 - Error in stats::ecdf(as.numeric(rvl$p/s.pm)) :
'x' must have 1 or more non-missing values
Calls: annotateCellTypesGSEA -> <Anonymous> -> bulk.gsea -> <Anonymous>
Execution halted
I can provide the dataset by email if needed
