Row 17 requests style code 16, which does not exist in the style file

[ksavani]

Hi Blair,

I want to run a DirectRT study in which participants are incrementally shown one image at a time on the screen. They are first shown one image and asked whether they want to reveal another image or to stop (i.e., skip to the next trial). They have the option to reveal up to 49 images. I wrote the DirectRT file but kept getting the error message "Row 3 has a missing value for one of its time columns". I checked many times for extra asteriks or spaces but could not find anything. Attached is the .csv file and the stim. The csv file has more than 256 columns (the max allowed by Excel 2003), so please open it with a text editor. I would be extremely grateful if you could suggest what might be going wrong with the file.

Thanks a lot,
Krishna

Krishna,

I believe the error is arising because of the last line:

1,1,0,0,1,~Please specify the location of the chocolate that you want to choose by providing position from the top and position from the left,rt:text,*

The above text is missing a location value. I think it may work if it reads:

1,1,0,0,1,~Please specify the location of the chocolate that you want to choose by providing position from the top and position from the left,"0,0,1",rt:text,*

I hope that helps,
Trevor

Same problem: "Row 2 is requesting a style code 0...". I carefully reviewed the input file, but can't find a problem. Can you help, please? Thanks!

Yulia--this looks like a regional settings issue due to the fact that some countries do not use commas in CSV (comma separated value) files.

Usually, setting regional settings in the Windows Control Panel to "United States" while editing your input files can solve this.

Hello,

I have the same issues as everyone else in this thread. The weird thing is that I only started to have this issue once I upgraded from DirectRT v2010.2 to DirectRT v2010.3. I upgraded to v2010.3 because of freezing issues. Anyways, I have attached the file I am trying to run. Can someone please take a look at it and tell me if I have done something wrong?

Thanks,

Max

Dear mkubota--I think DirectRT is having a problem reading the input file probably because there are no stimuli specified in column I for trials 4-19. Are you trying to present a blank screen in those positions? If so, try using a blank text stimulus by simply entering "~" in the cell (without the quotes).

Hope that helps,
Blair
