[FieldTrip] ANT Neuro Channel Loc

Dear Kinkini,

It's been a while since I have worked with ANT files, but if I remember correctly, the coordinates for the different electrodes are presented as Y-X-Z, rather than X-Y-Z locations in head-space (i.e. with respect to LPA, RPA, NAS). So try flipping the Y/X to X/Y columns and see whether this resolves the 90 degree rotation issue.

Best wishes,
Tineke Grent-'t-Jong

Dear All,

I am a new member of this group and have started using fieldtrip very recently.
I am using ANT Neuro wave guard 64-channel EEG cap for my study and I find difficulty in figuring out the respective chan loc file. However I have recently used 2D coordinates to prepare my own chan loc file, but its 90 degree rotated from clockwise.

Any information on this would be greatly appreciated.

Thanks and regards,

Dear Kinkini,

There is no channel location file unless you have digitized the electrodes yourself. I have attached a template electrode position of your system that I happened to use too. 
It can be used to compute neighbourhood struct for statistics or align to MNI template brain for source analysis.

You could use it to compute a layout file using ft_prepare_layout. Please type help ft_prepare_layout in the Matlab command window and evaluate the options. One of them, cfg.rotate is probably the cure for your 90 degree shift.
Wellcome the the FT list and good luck with your analyses Tzvetan

Hi  Tzvetan,

Thank you so much for your advice. Hopefully I will now be able to sort it out.

Cheers,

Kinkini
