1. 'onewaydata' is to create a data 'onewaydata' with 192 cells (each cell is a 16*34 matrix), including info such as spike rates and word types of trials of two sessions. It also did a oneway ANOVA for each electrode, and draw histograms of p-values and F-values of 192 electrodes for both original data and standardized data.
2. 'slidewindow' is to do slide window ANOVA for those electrodes which have shown significant p-values in 'global' ANOVA in above 'onewaydata' file. It also created plots to display these slide window p-values.
