addGeneExpressionMatrix cell name discrepancies

[grimmem1]

I am running into the below error when trying to combine a complex MIX-seq snATAC Archr object with the corresponding snRNA SE object. Long story short, if I know the location of the cell names in disagreement, it seems I could pretty easily transform them to match, but I am not having much luck finding which part of each data structure addGeneExpressionMatrix is using for the matching. Any insights are appreciated.

<simpleError in .addMatToArrow(mat = matz, ArrowFile = ArrowFile, Group = paste0(matrixName, "/", chr), binarize = FALSE, addColSums = TRUE, addRowSums = TRUE, addRowVarsLog2 = TRUE): CellNames in Matrix Group do not Match CellNames in Matrix Being Written!>
