i am not able to locate electrodes on the head model properly
Can you give more context and explain what your problem is?
Yeah so i am uploading the .dat file of head points but they are in 2d plane i am not able to properly fix the electrode position over the head anatomy
You need 3D positions, not 2D.
You could also use standard EEG positions, available in the menu "Add EEG positions".
Make sure you already followed all the introduction tutorials until #19 included, and the EEG/Epilepsy tutorial:
