All regridding is then done to that grid. Other regrid options described in :ref:`regrid` can also be used as normal. +"file_type" can be set independently for each input in multivariate mode. If not set for an input, MET uses file names and file content to determine the type. + +When setting a threshold to a percentile, some choices require both an observation input and a forecast input. When this is the case, it's assumed the indices match, so for example if forecast input 1 has such a percentile setting, then observation input 1 will be used to compute the percentile.
