coding ring electrode

[Abdülbaki YÜCEL]

Hello,

I have been using a ring electrode and a centre electrode for my high-definition tDCS research. I have tried this code 

roast('example/MNI152_T1_1mm.nii',{'FC5',1,'FC5',-1},'electype',{'disc','ring'},'elecsize',{[8 2],[35 45 2]},'simulationTag','controlmodelling');

I got the current modelling without problem, but the electric field (V/m) number seems to be too low or different from what I have read in other tDCS research papers that have done the current modelling. Could you check the code and please let me know what I have done wrong? Thank you. 

Best wishes,

Baki

Hi Abdülbaki, looks like the ring electrode is cut off by the image boundary. You can do a zeropadding of 20 and see if that improves.
