Getting error when running RunMCA

[anemartinezlarrinaga2898]

Hello,

Im trying to run CellID and Im getting the following error:

Error in (function (cond)  : 
  error in evaluating the argument 'x' in selecting a method for function 'as.matrix': `assay` must be one of "RNA", not "data".

This is the code Im using:

annotate.seu <-  readRDS(paste(path.file,file.name.seu,sep="/"))
matrix <- annotate.seu@assays$RNA@counts
metadata <- annotate.seu@meta.data

# Restricting to protein-coding genes
data("HgProteinCodingGenes")
matrixProt <- matrix[rownames(matrix) %in% HgProteinCodingGenes,]
# Generate a Seurat Object 
data <- CreateSeuratObject(counts = matrixProt, project = "Annotation", meta.data = metadata)
data <- data %>% FindVariableFeatures() %>% NormalizeData() %>% ScaleData()
data <- RunMCA(data)

any idea?

Thanks!

Might be related to this issue too #18 , but I think you might be able to get MCA to run by passing the argument
data <- RunMCA(data, slot = "RNA")
I'm not sure when this happened, but it seems like CreateSeuratObject has the default parameter slot ="RNA" now, but RunMCA is looking for slot="data" by default.
