Maybe a little bit late answerŠ

Files that contain raw data only are included in the Data.sta stack. A
".cat" file has to be generated from your original raw data file (binary)
through the CategVar module (readCateg File options). This file includes a
description of the table containing qualitative variables (number of row,
variables, the number of categories by variable, the number of rows by
category) that is used by the MCA module for running multiple
correspondence analysis.
You also can read the topic documentation 2.4 (available in English).
