Dataset used in conformer.py

[Yaqian-Xu]

First, thank you for open-source your code.
And I'm wondering where the .mat data you used in conformer.py, to be specific, line #278, #294 is from.
It seems neither the data format of BCI_competition_IV2a/IV2b, which is .gdf, nor the data format of SEED. These are three datasets claimed in README.md.
Thank you for clarifying.

I'm having the same issue. Seems like the way the data was formatted in a very particular way. And a lot of the preprocessing was particular for that use case. If you could share a sample file would be very helpful, please. @eeyhsong

Sorry for the late reply!

• You can use this code for transfering gdf. to mat. https://github.com/eeyhsong/EEG-Transformer/blob/main/getData.m
• And I found a mat dataset can be downloaded here http://bnci-horizon-2020.eu/database/data-sets
• For SEED dataset, you can refer to https://bcmi.sjtu.edu.cn/home/seed/seed.html
• I reshape the data after preprocessing to (trials, channels, samples) for the model.

Thanks for your interest!

Would you please share the shape of data label with us? Thank you for your sharing!

I'm interested as well in the shape of the data label, it seems like it's not a 1D array.
Thank you for your great contribution and for helping us out. @eeyhsong

@caikw0602 I'm mentioning you in case you found the right shape ?

[eeyhsong]

hello @caikw0602, @valentindjangone
Sorry for the late reply. It is just the 1D array.

Hi @eeyhsong

If I use the mat files from http://bnci-horizon-2020.eu/database/data-sets/001-2014/, it is not clear where are the labels for each trial.
If I use you script getData.m it requires a folder called "true_labels". Where is this folder?

Hello @toncho11,
You can download the results files here https://www.bbci.de/competition/iv/results/ .

Cannot run sload function successfully. Here is the error:
SLOAD: mexSLOAD('C:\Users\yameng.gu\BCI-eeg-date\CNN\data2\A01T.gdf') failed - the slower M-function is used.
Unrecognized function or variable 'H'.

Error in sload (line 1232)
if strcmp(H.TYPE,'CNT');

Error in getData (line 14)
[s, HDR] = sload(dir_1);

Wonder if you can upload an example input data for Conformer python file. So i can create my own. Thanks
