I'm trying to import raw EEG data in ASCII .txt file format to EEGLAB. EEG activity was recorded from 32 channels at 256 Hz and is aproximately 1:30 hour long, resulting in a 222.879 kb file. I was able to import it using EEGLAB version 7.9.2.20 (I tried the latest version first, but kept obtaining an "out of memory" error), and save it, but when I try to load the dataset I get the following message: "EEGLAB error in function eeg_getdataact() at line 162: Out of memory". Due to limitations in my acquisition software, I can't export the registry in other more compact formats like .EDF. </div><div><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">I thought one possible solution would be to
divide the file in different parts, filter and extract the epochs from each part, and then concatenate them all before ICA analysis, but I'm concerned that filtering each part separately and reuniting them later may not be an adequate procedure. What do you think? I would very much appreciate suggestions and comments.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">Thank you!</div></div></body></html>
