SSVEP_TSINGHUA

[tahaolan]

Hello, I want to know how to use dataio_create_epochs_SM_Tsinghua.m. Where should the folder in the code such as Freq_Phase.mat be created?Thank you.

[okbalefthanded]

Hi, Create a folder in the main toolbox folder, next to datatio, evaluation etc.., the datasets folder should look like this:

datasets 
│
└───ssvep_tsinghua_jfpm
│   │   S1.mat
│   │   S2.mat
│   │
└───another_dataset
    │   s1.mat
    │   s2.mat

So at the end the toolbox folder tree will look like this:

bci_toolbox/
|___dataio
|___datasets
|___evaluation
|___machine_learning
|___...

Thank you, I also want to know what values ​​should be set for epoch_length and filter_band

[okbalefthanded]

both are vectors of 2 elements, epoch_length can be any length between 0 and length of samples (6 seconds in Tsinghua). keep in mind that values of epoch_length are of type int and in milliseconds, as for filter band values should cover the stimulation frequencies up to their 3rd harmonics. example: epoch_length = [0 1000] (epochs of 1 second) filter_band = [5 60] (frequencies from 5 to 60 hz)

Why is it reported that the index exceeds a part of the range

[okbalefthanded]

This error is raised when the dataio_create_epocsh_SM_Tsinghua can't find datafiles. before running any evaluation make sure to run the setup.m script first and to always execute data_create_epochs functions from the bci_toolbox main folder.

Thank you, I have another question why L1MCCA and ITCCA can't run

[okbalefthanded]

ITCCA wasn't running due to an unmerged commit between master and dev branches, you can download the current code it will run well. Unfortunately L1MCCA requires longer debugging which I can't go through, however I advise you to check the authors code that I translated into this toolbox : https://www.mathworks.com/matlabcentral/fileexchange/50876-mlrforssvepbci_demo

Hello, does this code use 64 channels? If I only want to use Pz, PO5, PO3, POz, PO4, PO6, O1, Oz and O2, what should I do?

[okbalefthanded]

There are two possibilities : 1 - select the channels after reading each subject raw file in dataio_create_epochs. or 2 - select the specific channels after reading epoched files in run_analysis function.
