+AnyWave allows to filter channels depengind on their modality.   
+The GUI will display the different channels type detected in the current dataset. However, sometimes, depending on the Montage, you may have channel modalities not detected.   
+Use the Add combo list to specify the modality you want to apply filtering options on.
+
+Note that all the filtering options are saved by anywave automatically and apply again the next time you open the same dataset.
