ES32: Screenshots

Here you can find a couple of screen shots of ES32. Click on the thumbnail to get the full-sized version.

Screenshot This is ES32 while browsing through an EEG file.
After averaging some data, ES32 presents you with an Average Report, which is captured here. As you can probably see, the analyzed experiment had two conditions (congruent and incongruent) and 21 subjects. The data of subject 21 were not analyzed, probably because the data were somehow messed up. Subject 13 is deactivated (probably for good luck). And somebody is about to open the .EEG file of subject 2. You can also see how many sweeps each subject contributed to the grand average of each condition. Screenshot
Screenshot This is the "Comparative View". For each electrode and condition, you get one button. You are thus able to view your grandaverage and compare the waveforms of selected conditions on selected eletrodes.
If you want to get an idea about how good your data are and which differences might be significant, ES32 can compare the data of two conditions with a point-by-point t-test. The result of this function can be seen here. You get the original data (the red and the blue waveform) and you get a third "waveform" that shows you whether the conditions differ significantly at each point in time (the green one). If the green line is at the baseline, there is no difference, but if it is between the other two, these have a significant difference. Screenshot
Screenshot ES32 also allows you to calculate difference potentials. The dialog with which this is accomplished can be seen here. In this case, we calculate a simple difference potential by subtracting the data of the incongruent condition from the data of the congruent condition. But the calculations get a little more complicated, if you check the "Calculate LRP" checkbox. With this option, ES32 will calculate lateralized potentials (from any electrode).
