As we are encountering problems while running some third-party analysis tools on our ".dat"-files, we'd like to know how the output-files differ between those versions? We are using an ".exp"-experiment, that was programmed in Inquisit 3. If we run it with Inquisit 3, we get perfectly working data-file. If we run the same ".exp"-experiment in Inquisit 5, the analysis tool encounters a problem. In both cases ".dat"-files (not .iqdat) are written. Thank you very much in advance. Best regards, Dominik

Regards, Sean

Best regards, Dominik In addition to what Sean said, there's another difference that might trip up the analysis routines. If your .exp uses the default data recording scheme -- i.e. no <data> element's /columns attribute specified -- .dat files generated by Inquisit 4 and 5 will have an additional column compared to the ones generated by Inquisit 3. The reason is the introduction of group ids as an additional option for condition assignment starting with Inquisit 4. Whereas an Inquisit 3-generated .dat would start with the following columns date time subject build blocknum the Inquisit 5-generated .dat would look like date time group subject build blocknum i.e., there's an additional column, and consequently all the following variables are shifted to the right.
