JATOS Tryout Server
Cortex is a running JATOS server where you can try out JATOS in the Internet instead of your local computer:
https://cortex.jatos.org (log in with firstname.lastname@example.org and abc1234 or with a Google account)
This is a normal JATOS installation with many example studies already imported (test account only). You can run the examples or import your own studies if you want to test them in a JATOS running on the Internet.
But be aware that every day this JATOS server will be reset to its inital state and all changes, uploaded experiments and data will be lost. Additionally, there is only one log-in account that anybody can use (except you use a Google account), so everybody will be able to see, delete and take your data. In other words, DO NOT use this JATOS instance to run your studies online. It is only there to provide an example JATOS for people to try out.
