Hello Hisham (or anyone else). I have what seems like a somewhat similar problem.
Each photo in my stimulus lists was given 3 tags (one for each of three different tag sets). A correct response is based on a key press corresponding to the tagging from one of those 3 tag sets. The other two tag sets designate information about the photo that will be analyzed in relation to rates of correct/incorrect responses.
When I look at the data after practicing the experiment, the designation of each recorded response as correct/incorrect is accurate but the tag labels are weird. Specifically, many of them note two conflicting labels for each response-- one for the event (which is correct) and one for trial (which is incorrect). For example when a tag should just say “Neutral” Cedrus data viewer says “Neutral (event) Happy (trial).” Some recorded responses have this duplicate incorrect listed tag for all three tag sets, some for just one or two. I don’t know where the tags that say they are tied to a trial are coming from. How do I get rid of the trial tags and just keep the event tags?
