Neuropype: motor imagery tutorial, questions
Greetings. I'm trying to motor imagery tutorial on the website using a Cyton. Using the GUI I can confirm there is EEG, and the LSL stream seems to be recognized. I went through the calibration to create the xdf file, and I edited the pipeline as specified in Neuropype. And the following happens:
Loading pipeline... INFO: execution started INFO: execution resuming INFO: Importing XDF file C:/Recordings/CurrentStudy/exp1/slater1.xdf... INFO: Imported file C:/Recordings/CurrentStudy/exp1/slater1.xdf. INFO: Imported file C:/Recordings/CurrentStudy/exp1/slater1.xdf. INFO: Resolving data stream (name='obci_eeg1')... INFO: Applying FIR filter... INFO: CSP model is training now... ****ERROR: The following error occurred in node Common Spatial Patterns: shape of data ((2, 4)) must match lengths of axes ((2, 6))**** WARNING: The channel labels of the given stream were missing or incomplete. Auto-generating labels. INFO: LSL: Data stream obci_eeg1 acquired. ERROR: CSP must be trained before it can be used
Honestly I'm not sure where to begin looking for the "Common Spatial Patterns" node to figure out why the data shape doesn't match the axes length. If I just run the pipeline without editing it (with no EEG input from my headset) it executes appropriately. Where should I start looking? Any suggestions will be appreciated. Thanks!
