Can a missing XID device only give a warning, not throw an error

Hence, programming and testing of experiments is mostly done on our office computers without a Cedrus device attached. We just add both Cedrus and keyboard codes as valid/correct responses. With Inquisit 3, changing one single line in the <defaults> section of a script allowed to switch between XID devices and keyboard. With the new <xid> element in Inquisit 4 we have to delete the whole XID element to test or run scripts on non-lab computers. It would be nice if Inquisit could throw an XID error only if the xid device was used as an "/ inputdevice" somewhere, and give just a warning message otherwise. Kind regards, Malte

This would open the road to data loss in cases where a device is supposed to be present (i.e. in your "lab" configuration), but Inquisit is unable to communicate with it. One alternative I can think of is to use conditional <include> elements with e.g. a "special" subject id to automatically run your non-lab vs. lab configuration. This would require zero changes to the actual script (minimal example attached; use subject id "test"). Hope this helps.
