logdata	Single logical indicating whether the raw RFI values should be logged.
tech_reps	Single logical indicating whether there are technical replicates.
convert_neg	Single logical indicating whether negative values should be converted to zero (0).
AB_col	Name of the column containing antibody name or number, as string. These names or numbers will become rownames of the output matrix.
