No one can help you (yet) because you didn't give enough information for anyone to help you.

You cannot find the best features directly. Because for each problem we can use of different set of features. Nobody can say which feature is the best. It depends on your problem and your data. Extract the features of your data, then use one of the feature selection methods to give you suitable features or you can use of different features and finally compare the results. Test your data and evaluate the results by one of the performance evaluation methods. Good luck.
