Training data sets for mental commands and facial expressions are stored in training profiles. From EmotivBCI v3.6.5, each headset type with different EEG channels will have different training data sets, then different training profiles.

Training profiles are attached to your EmotivID and your EmotivID account can store multiple training profiles. You may want multiple training profiles to experiment with different training strategies or to customize for different applications.

To get the best results, please ensure that every time you try to use different training strategy you create a new profile.

When you train mental commands or facial expressions in EmotivBCI application, you will be requested to select or create new training profile if you haven't created one before.

Note: When you run BCI applications or integrations, such as those created by Node-RED, you will be asked to select which training profile you want to use.

If you upgrade from EmotivBCI before v3.6.5, your existing training profiles will become read only. See .

Since EmotivBCI 3.6.8, you can convert to training mode so that you can train it, but only with Epoc or Flex headset.

Please note that after converting to training mode, these profiles are actually written in a new data structure and cannot work with EmotivBCI before 3.6.5.

If you want to showcase EmotivBCI to a friend or colleague it is extremely important that you do not let them use one of your existing training profiles OR create a new profile under your user account as this will result in data pollution and reduce the accuracy of the detections for your account. Specifically for these cases we created Guest mode.

To use Guest mode click “Use guest mode” on the “Select training profile screen”.

Guest mode will create a disposable profile that will remain active until the next time you access the app or choose a different profile.

Guest profile data is not stored in your EmotivID account. If you would like to save training profiles for another person, you can create and sign into the application with a different EmotivID.

• Your training profiles

• Creating a training profile

To Delete a training profile hover over the profile you would like to delete and click on the "trash" icon and click “Yes, delete” in the confirmation pop up.

To edit the name of a training profile hover over the profile you would like to rename and click on the "pencil" icon and change the name of the profile in the pop. Click “Save” to save your changes.

To change the training profile you are using, access “Select training profile” screen from the user dropdown menu on the top right of the application header and click on “Training profiles”.

Before create a new training profile, you must connect an Emotiv headset you are going to train with.

After your headset is connected, click “Create new profile” on the “Select training profile” screen and enter a profile name in the pop up screen before clicking “Create”.

If you upgrade from EmotivBCI before v3.6.5, you should notice that we change the format of training profiles so that the existing training profile (i.e. created before v3.6.5) will not be fully supported. We call them readonly profiles which can only run at a live mode and cannot run on training mode. If you still want to use this profile in training mode, see how to .

These training profiles only support headsets with 14 EEG channels (i.e. EPOC X and Flex with EPOC X config mapping).
