 \details{
 Users wanting to use \code{FUN_CRIT} functions that are not included in the package must create their own InputsCrit object accordingly. \cr \cr
+The syntax of the power transformation can be written in numerical form or as a string of characters, for example for a square: \code{transfo = 2}, \code{"2"} or \code{"^"2"}.
+\cr \cr
 The epsilon value is useful when \code{"log"} or \code{"inv"} transformations are used (to avoid calculation of the inverse or of the logarithm of zero). The impact of this value and a recommendation about the epsilon value to use (usually one hundredth of average observation) are discussed in Pushpalatha et al. (2012) for NSE and in Santos et al. (2018) for KGE and KGE'. \cr \cr
 We do not advise computing KGE or KGE' with log-transformation as it might be wrongly influenced by discharge values close to 0 or 1 and the criterion value is dependent on the discharge unit. See Santos et al. (2018) for more details and alternative solutions (see the references list below). \cr \cr
 Users can set the following arguments as atomic or list: \code{FUN_CRIT}, \code{Obs}, \code{VarObs}, \code{BoolCrit}, \code{transfo}, \code{Weights}. If the list format is chosen, all the lists must have the same length. \cr
