<div dir="ltr">Hello<div><br></div><div>could someone please explain to me a little more about Epoch Extracting in terms of how many times should i use the Epoch extracting if i have 4 events in each run of my dataset</div>
<div><br></div><div><a href="http://sccn.ucsd.edu/wiki/Chapter_05:_Extracting_Data_Epochs">http://sccn.ucsd.edu/wiki/Chapter_05:_Extracting_Data_Epochs</a></div><div><br></div><div>i am working on an eeg dataset that consists of several runs on about a hundred subjects, each run contains event annotation file and i was wondering if i have to execute the epoch extracting on each file, and if so, how many epochs should i extract? does it depend on the number of events ? or it it one epoch per run ? or does it depend on my need ?<br>
i am trying to understand a little more about epoch extracting in general and its importance to ERP analysis for feature extraction</div><div>this is the dataset i am studying <a href="http://www.physionet.org/pn4/eegmmidb/">http://www.physionet.org/pn4/eegmmidb/</a></div>
<div>any help is really appreciated</div><div><br></div><div>Thanks</div></div>
