Emotiv experiment - propblems in creating file .emotiv_creds

Hello, everyone!
Currently, I am trying to connect Psychopy to EmotivPro to run my experiment in the lab, but I have a problem to create the file “.emotiv_creds” in my home directory. I just used txt file created in my home directory and put there the ID and Password which I got from EMOTIV website (cortex).
Please I hope you can help me as soon as possible:))

I am having the same problem. Did you find a solution? Thnx.

I have a similiar problem. Once I’ve tested my experiment (with emotiv components in test mode) and worked, I tried to connect psychopy with emotiv. The log info says there is an error, because the .emotiv_creds does not exist.

Could someone post the format or a hint why It does not recognices the file (and thus aborts the experiment)?

Thank you.

Here is the log info

Experiment ended.

There is a missing slash from this error message.

emotiv should be looking for C:\Users\ramon.emotiv_creds (assuming that the file is suppose to start with a dot.

Thank you! The problem was that the emoti_creds had the txt extension. My bad. Now it works perfectly.


Delete the .txt extension in the file. It worked for me
