jzip generation from osexp file

bijsterveldjvan

Dear all,

I'm trying to create an automated pipeline for acceptance testing of a jatos server. Since the end-users often need to link their osexp experiment to a Qualtrics survey, I wanted to incorporate that into the tests.

In order to test this, I need to generate an osexp experiment with an embedded hyperlink that I only know at runtime. I currently change a variable name in the .osexp file with string replacement, but I haven't found a way to (programmatically) convert the osexp file to an (uploadable) jzip file.

In short: is there a way to convert an .osexp file to a .jzip file without using the opensesame user interface? I have found the exp_to_jzip function in the osexp python module, but it seems to be broken and I haven't been able to fix it yet.

Thanks in advance for your insights :)

Hi @bijsterveldjvan ,

The function that converts an experiment to a JATOS jzip is indeed exp_to_jzip() , which isn't broken but it's also not intended to be used externally. (Although you're free to do so, of course.)

• https://github.com/open-cogsci/opensesame-extension-osweb/blob/master/osweb/convert.py#L151

I would say there are two pragmatic ways to handle your case:

• Have the experiment retrieve the URL from a predictable location (such as a file that is publicly accessible somewhere), and use this to communicate the URL to the experiment, as opposed to hard-coding it into the experiment.
• Unzip the jzip , patch the .osexp file, and then rezip it back together.

Do either of these options work for you?

Hi @sebastiaan,

Thanks for the response!

In the meantime we've solved the problem by sending the link as an argument when running the study through a JATOS study link. Your options also sound practical though!

Thanks again,

Jens
