Warning "Unknown method" when plotting topgraphy map

Post by pieterkubben » 08 Jun 2012, 21:13

Using MatLab R2012A on Windows 7 (64 bit) I succeeded in using the Offline Analysis tool for creating feature maps and spectra plots. I created an eloc file to be used with my EEG headset (Emotiv EPOC) which opens fine in the elocHelper (used to check).

Now, if I enter the spectra channels and topo frequencies in the Offline Analysis tool, the spectra plots comes up, but when loading the topography plot it gives a warning message "Unknown method". The Topographies Figure window loads with an empty graph canvas (X en Y axis), but no content. See attach for a screenshot.

Tested with some sample data provided with the BCI2000 installation, same issue.

Any idea what is going on, and how to solve this?

Thanks,
Pieter

Has there been any progress on this issue?

I just ran into the same problem, using 64 channel EEG data recorded with Neuroscan Synamps RT equipment.

Hi,

thanks for the bug report. The code has been updated on SVN to work with recent versions of Matlab.
