# Your training profiles
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 [Readonly training profile](/emotivbci/training-profiles/readonly-training-profile.md).
