<br>
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.<br>

Dear All,<br>
<br>
I am a new member of this group and have started using fieldtrip very recently.<br>
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.<br>
<br>
Any information on this would be greatly appreciated.<br>
<br>
Thanks and regards,<br>
<br>

Dear Kinkini,<br>
<br>
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. <br>
It can be used to compute neighbourhood struct for statistics or align to MNI template brain for source analysis.<br>
<br>
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.<br>
Wellcome the the FT list and good luck with your analyses Tzvetan<br>

Hi Tzvetan,<br>
<br>
Thank you so much for your advice. Hopefully I will now be able to sort it out.<br>
