Dear Sanjaya Vipula Bandara - as Anna - Marie Beck has said, you have asked a very broad and open question. Are you using Nihon Kohden apparatus or are you considering using it. It is very high quality, reliable equipment.
If you need to do some processing and analysis on your signals you can export the raw data and enter it to MATLAB using EEGLAB toolbox for example (or other software)..
You can ask a more specific question if it's not what you wanted to know.
I found this post after a long time looking for toolboxes or plugins to work on .eeg files and I found a good tool, it is called Brainstorm and it is a collaborative, open-source application dedicated to the analysis of brain recordings: MEG, EEG, fNIRS, ECoG, depth electrodes and animal electrophysiology.
can analyze the data on matlab in real time ?? and what is the tool used to open the data coming on usb port?? do any one have the usb port drive of the junction box for windows 64??
