Hi Jason,

It's great you got this far. However the Java API is focused mostly on querying and updating data, and not higher level operations like 'create a study'. Without investigating, I suspect this error is because there is no study-defined yet, so it won't allow you to update the study properties.

I think you might want to look into the documentation for our "study archive" format. The study archive is a .zip of files containing the study data and meta-data.

You can then simply create a new folder and import. We support one study per folder, but multiple folders per project, so multiple studies per project are supported. To get started you can look at the demo study archive.

and checkout the tutorials.

I hope that helps you get started,
Matt
