The first plot is a general overview of how much good data has been found in your data set. If the % of time and the % of channels removed from your data is very high you might want to reconsider your experiment modality. From the figure below:

The study option will present something very similar to these pie graphs but it will be in a stack bar graph, and be done for all of the data sets loaded. Going up the y axis is the subject number, and the x axis is the percentage of channels or time.

Component classification can only be done on files that have successfully run through the complete dipfit script. It this script we make use of a plugin tool box developed by Laura Frolich called IC_MARC (classification of Independent Components of EEG into Multiple ARtifact Classes). This plugin will look at the components generated by AMICA, and attempt to classify them by their characteristics. It then saves the probability of the component belonging to one of the following categories.
