I received some questions regarding MindAffect installation.
I didnt mention about that in my tutorial but there might be some problems with execution pip install -r requirements. txt command. If you are lucky to have this error just install libraries from requirements.txt file manually.
Also If you have a newer version of python I recommend to install 3.8
After installing MindAffect and using the commands in the tutorial for testing, the tutorial states that if you press 2 now, you should see a flashing "buttons" grid, as shown below. You should see a random Panic briefly flashing green (it is the target), then rapidly flashing and finally turning blue (indicating that it has been selected). When I actually operated, there was no blue display in the end, and I don't know where the problem lies. I sincerely hope you can help me, thank you.
What Java version do you have? When you go to Electrode Quality do you see that all electrodes have value 0.5 that doesnt change?
I am glad to receive your reply. The question you asked is shown in the picture. Also, I am using the window11 system, and I am not sure if this has any impact. Thank you again for your reply.
Hmm from your screenshots it looks good.
Java version also should not be the problem here.
Have you done Calibration before going to Cued Prediction?
Remember that without calibration (training Machine Learning model) the prediction wont work.
I have a few questions regarding your response to me, and I look forward to your answer:
1. I am currently using the built-in virtual data, and even after data verification, the prediction still does not display blue
2. Is it necessary to use real data for verification and prediction in order to achieve the desired experimental results? A blue box appears.
Once again, I would like to express my sincerest gratitude for taking the precious time to answer my question.
MindAffect also works with fake data. Lets break this down:
1. You run the app 'online_bci' with fakedata_test.json file.
2. In the main menu you choose Calibration. After calibration you should see the result of that process (100% success)
3. Now you go to Cued Prediction and blue color for target never occurs.
Is that what happens? Feel free to write step by step what you do so I could find the problem. If you follow the steps above please check your logs and search for any exception or error. When you find it please share the screenshot or paste the error
edit
remember that everytime you run the app you need to repeat the calibration process
Those are great tips, Pyotr !
