Created attachment 54 QuickCap_template_fiducials I am collecting EEG data from a SynAmps RT 128 channels. I am using a QuikCap NSL, which although has 128 electrodes, does not follow standard 10-20 localisation. I'm trying to create a layout to visualise my data using the template fiducials of the cap. My script currently looks something like this: cfg =[]; cfg.elecfile='QuikCap_128_NSL.sfp' cfg.rotate=0; cfg.projection='polar' lay=ft_prepare_layout(cfg); ft_layoutplot(cfg) However, the electrodes seems to be shifted towards the back of the head. I have tried to realign the electrodes (using ft_electroderealign), but I get similar results. Please find attached the 'QuikCap_128_NSL.sfp' file. Thanks in advance for the help.

the layout file should be added to fieldtrip/template/electrode

Sorry for the late response. Added & comitted the layout file. If you encounter any problems with this layout or with any other layouts, feel free to contact me or just open a new bug. Next time, I'll be a bit faster :)

I just found out that the template file contains a 2D layout and not 3D electrode positions. I have moved it to the template/layout directory. mac001> svn commit . ../layout/ Deleting electrode/QuikCap_NSL_128.mat Adding (bin) layout/QuikCap_NSL_128.mat Committed revision 6915.
