Reading in .csv files from external storage

Brent

Hi,

I am designing an online experiment where each participant will go through a unique sequence of trials. I currently have one .csv file per participant with their unique trial sequence, which makes it impossible for uploading via the file pool to use in an online experiment. I have seen other discussions on how to read in images and sounds from external sources and I was wondering if the same would be possible for .csv files. Specifically, I would like to be able to only load in 1 .csv file for each participant, without having to upload all files directly via the file pool.

Any help would be greatly appreciated!

Best,

Brent

Hi @Brent ,

It is possible to read in external CSV files from a URL using an inline_javascript item. But it's quite complex and probably not necessary. Even if you have a lot of participants, adding all csv files to the file pool is probably still the easiest solution. Is there a specific reason you don't want to do that?

Hi @sebastiaan,

Thanks for the quick reply.

I initially had all files in the file pool, but this exceeded the recommended maximum size (Error: OSWebCompatibilityError).

As I don't need all participant files to be loaded for every participant, I thought adding only the relevant files from an external source could be a solution.

Hi @Brent ,

You can disable the compatibility check in the OSWeb and JATOS control panel. As long as the experiment doesn't grow disproportionately large (say <50 Mb) it's ok, and it will make life much easier.
