**DISCLAIMER**: This tutorial is not intended to substitute other, more in-depth [tutorials][1]). It is a simpler, condensed version for educational purposes, aimed at the members of the department to which this workshop was given. *** *** This component contains all the materials for the hands-on session (which can directly be downloaded as a ~2GB *.zip* file): + **2017.09.15_MyEEG_preprocessing.pdf**: pdf of the Powerpoint presentation: description of experiment whose data were analyzed during the workshop and example of common artifacts in the EEG signal; + **N1_EPN_luminance**: master folder containing the following sub-folders: + **data**: raw EEG data of two participants, ss01 and ss02. Unzip to the **data** folder on your computer; + **papers**: papers describing the dataset and providing more information on some preprocessing steps; + **preproc**: *.zip* file containing intermediate results of each preprocessing step, summary of rejected epochs and interpolated channels. This file is included in case some of the attendees will not be able to run the preprocessing due to unforeseen technical problems (at least they will be able to see the end result). Unzip to the **preproc** folder on your computer; + **scripts**: contains: + *N1.EPN_luminance.m*: commented Matlab script with all preprocessing steps; + *BioSemi68_Leipzig.locs*: electrode coordinates for the current datasets; + *BIOSEMI_Cap_coords_all.xls*: electrode coordinates for BioSemi systems with different montages (see also [here][2]); + *toolboxes_functions*: folder containing [EEGLAB][3] with some popular plugins (unzip *eeglab_14_1_1b.zip* to the **scripts** folder on your computer) and some useful functions.
