A question about getABSignal() function with DNA methylation data

Hi Johnson, I noticed that the `assay = "bisulfite"` argument of `getABSignal()` function doesn’t seem to be working. I wanted to ask if the `getABSignal()` function is compatible with WGBS data. The error message is listed below. Thank you so much for your help!

Calculating eigenvectors.
Error in match.arg(assay) : 'arg' should be one of “rna”, “atac”
