Hello, good morning
I am Vahid Ranjbar Aynaddin, a student at Tabriz University.
I am working on brain signal analysis, please explain the conditions and how to use EEG data in Brainstorm.
Thank you

You can start by reading the introduction tutorials, using the MEG example datasets, in order to learn how to use the software. Then read advanced tutorials related with your interests, starting with the EEG/Epilespy tutorial:

You can process recordings from most EEG/MEG acquisition systems:

Hello doctor, good morning
I am the servant of Vahid Ranjbar Ainaddin, a master student of medical engineering from Tabriz University.
We need data to analyze the functional connections of the brain by EEG signals. Can this data be found from the brainstorm itself? If it is possible to find this data in a brainstorm, please help.
And is it possible to use data other than brainstorming data?

Dear Professor, The data we are looking at to examine the functional connections of the brain is in the form of a data table of EEG signals that we have found in the environment outside the brainstorm.
Now we want to enter this data into the program, but we encounter a problem when entering the data.
Of course, we have read all the tutorials and processed them with the relevant example. But we can not import the EEG data as a data table.

You can save your data:
- as a Brainstorm .mat structure: https://neuroimage.usc.edu/brainstorm/Tutorials/Epoching#On_the_hard_drive
- as a text file
- as a .mat file with only one field, being you data matrix [Nchannels x Ntime] or [Ntime x Nchannel]
The use the menu Import MEG/EEG data, selecting the appropriate file format.
The best would be for you get the original datasets, in the original file format.
Hello Professor
I imported the EEG data that I imported in the brainstorm with the EGI GES 300 device with 256 channels, but I do not have a file location sensor for this data that I can manually locate the electrodes.
Brainstorming itself has introduced the use of the default channel mode to solve this problem, but I choose any of the default ones. The electrodes are not in place, even though the MRI location is recorded correctly. I did.
What is the recommended method for importing EGI GES 300 file location sensors with 256 channels?
Thanks

"EGI GES 300" is not the name of the cap, it designates the amplifiers.
On them, you probably have HydroCel 256 nets, which are available in the default list of EGI caps supported by Brainstorm.
If you have a cap that is not available in the list, please share their default 3D positions - ask them to the EGI customer support if you don't have them.
Make sure you read all the introduction tutorials and the EEG tutorial before trying to process your own recordings.
