I recented used Inquisite 4 to develop a new IAT task. Based on the Tutorial, I only modified the "attribute" stimuli and the "target" stimuli. However, when I run the experiment with the modified script, there is an error message said that "Unable to access the data file at "IAT_rawdata.iqdat". Verify this is a valid path."  I checked that I have the rawdata file and summary data file both in the smae folder with the script.  Has anyone encountered similar problem, if so, could anyone provide some tips on how to solve this problem? Thanks!
