 The \code{conversionTable} table follows a pre-defined format: 4 columns in any order (\code{from_desc}, \code{to_desc}, \code{from_name} and \code{to_name}) and any given number of line, each line referring to a specific matching to be treated. For instance, if a line has the values \verb{from_desc = CXCR5 B610-ECD-A}, \verb{to_desc = CXCR5 ECD-A}, \code{from_name = FL2-A} and \code{to_name = FL11-A}, it means that any occurrence of a parameter (in any \code{rds} file) named \code{FL2-A} which also matches the description \verb{CXCR5 B610-ECD-A} will see its values respectively replaced with \code{FL11-A} and \verb{CXCR5 ECD-A}.
