ActSds and OdfSds: Programs for converting INTERACT and the Observer data files into SDIS timed-event sequential data files

Abstract

In this article, we describe programs for converting Mangold International's INTERACT and Noldus Information Technology's The Observer data files to sequential data interchange standard (SDIS) timed-event sequential data files. Users who convert their INTERACT or The Observer data files can then take advantage of various flexible and powerful data modification and computational procedures available in the Generalized Sequential Querier, a program that assumes SDIS-formatted files.
