Match! is able to perform a semi-quantitative analysis of the sample using the so-called "Reference Intensity Ratio method" (RiR-method) (de Wolff, Visser (1964)). The analysis is performed automatically if at least two entries have been selected as matching. The quantity (weight %) of each selected phase/entry is displayed in the "Quant.(%)" column of the match list and of course also in the report. However, the analysis can only be carried out if all entries which have been selected as matching contain I/Ic factors. As an exception, you can activate an option to let Match! use an I/Ic factor of 1.0 which might be helpful in some situations. Normally, if only one of the selected entries does not contain an I/Ic factor, the values for the remaining selected entries will not be displayed as well.
You can check if an entry contains an I/Ic factor before selecting it by having a look at the column "I/Ic" in the candidate list in which a corresponding value must be given.
