addData

[Aysja Johnson]

Is there any reason that thisExp.addData('just checking', 5) wouldn't work? I didn't change anything in the setup of thisExp (I left it as what psychopy automatically created). When I look at the csv file it adds the header "just checking" but doesn't associate the value 5 with it. I've tried lists and numbers. Any thoughts?

Thanks!

Hi,

— Where/when do you do this? If it isn't on every trial (e.g. just at the end of the experiment), there will be blank cells.

— What happens if you don't have a space in the column name. e.g.
thisExp.addData('justChecking', 5)

Michael

Hi Michael,

Thanks for the quick response. Originally I was doing it in the 'End Routine Trial' section of code but I've tried it in multiple places now; before the experiment starts, every time a key press is updated. and right before the experiment ends. I also tried deleting the space. Nothing has changed -- it still adds the header every time but not the value associated with it.

Just tested, and it works fine for me on the latest release. Would have been surprised if this was broken, as it would affect many people. So it will have to be something unique to you.

Are you sure there isn't any code elsewhere which could be saving blank values to this variable, which could over-write the '5'?

Perhaps you should click the "Compile script" button and search for all instances of "Just checking" to see if anything unexpected is happening (ideally, it should appear only once).

Regards,

Michael

It works for me too, but I see it not work in some conditions.

It did not work if I made an experiment and the only thing in the experiment was a code component with the code to do thisExp.addData(). There I get a column but not the data value (5). But if I add a keyboard response to the experiment, then the 5 also shows up in the data file.

Instead of the keyboard component, if the code in the code component also contains "thisExp.nextEntry()" (no quotes) after doing the addData, then it also works.

Hi Jeremy,

Thank you so much! I added thisExp.nextEntry() after calling addData and it works perfectly.
