Classification using GMM:how to use GMM for classification after doing the pca

Using Matlab ,I have a one Healthy data and 7 Faulty data wich are composed of 9 variables and after PCA on my healthy data I have got 3 PCs. Now When I'm projecting the faulty data on the PCs I get overlaping between healthy and faulty data. Now I need to do GMM(gaussian mixture model) to get my data clustered and how to get the threshhold but i don't know to to do so. Please If anyone can help me it's for my final year project
