Is it possible to convert EEG dataset into csv file and then analyse using R tool or weka??

Actually, We are doing Epilepsy Detection Project. Due to some reasons it is compulsory for us to convert .edf files into csv format. if anyone knows about the code please tell me. I didn't find any helping material from internet.

I would like to train 20 file EEG on Neural Networks so for easy to train them I need to change them to CSV file and pack them to rows. That bring in the Question, Is it possible to convert EEG raw cnt to csv on python?

I am seeking for the best signal processing package or course in python, especially for EEG/MEG signal processing, what packages are available? and which is the best one?

I am new with EEG related terms and I am experimenting using BCI Competition IV #1 dataset. What does EEG signal epoching mean? and how can i extract epochs knowing that my eeg data is a matrix (time x channels).

Thank you

Hi Everyone, I have an EEG signal with 4000x56 data, where 56 is the number of trials and 4000 are the data points.

I am looking to separate data according to frequency ranges (theta, delta, gamma) in python. How can I do this?

Can you kindly let me know how can I get data for different frequency bands?

Thank you.

Hi,

I am totally new to the field of EEG signal analysis, but I am exploring it to see potential processing/analysis techniques to be designed and implemented on FPGA for onsite clinical decision support. So, I have raw EEG signal in edf format which I have successfully implemented into matlab and ran the following code to calculate the relative power (based on a code I found online). However, the results do not match some done by another professional in this area (very close, but does not match). Would anybody help me improve the code below to get more accurate results or suggest other venues. Note: if you advise me to go to EEGlab, please point me to the exact steps to do there. 

Thanks in advance!

Any help highly appreciated!

% Fs is my sampling frequency, x is my EDF data imported into matlab

Fs=1000;

t=1/Fs;

S =x;

waveletFunction = 'db8';

[C,L] = wavedec(S,8,waveletFunction);

%% Calculating the coefficients vectors

cD1 = detcoef(C,L,1); %NOISY

cD2 = detcoef(C,L,2); %NOISY

cD3 = detcoef(C,L,3); %NOISY

cD4 = detcoef(C,L,4); %NOISY

cD5 = detcoef(C,L,5); %GAMA

cD6 = detcoef(C,L,6); %BETA

cD7 = detcoef(C,L,7); %ALPHA

cD8 = detcoef(C,L,8); %THETA

cA8 = appcoef(C,L,waveletFunction,8); %DELTA

%%%% Calculation the Details Vectors

D1 = wrcoef('d',C,L,waveletFunction,1); %NOISY

D2 = wrcoef('d',C,L,waveletFunction,2); %NOISY

D3 = wrcoef('d',C,L,waveletFunction,3); %NOISY

D4 = wrcoef('d',C,L,waveletFunction,4); %NOISY

D5 = wrcoef('d',C,L,waveletFunction,5); %GAMMA

D6 = wrcoef('d',C,L,waveletFunction,6); %BETA

D7 = wrcoef('d',C,L,waveletFunction,7); %ALPHA

D8 = wrcoef('d',C,L,waveletFunction,8); %THETA

A8 = wrcoef('a',C,L,waveletFunction,8); %DELTA

POWER_DELTA = (sum(A8.^2))/length(A8);

POWER_THETA = (sum(D8.^2))/length(D8);

POWER_ALPHA = (sum(D7.^2))/length(D7);

POWER_BETA = (sum(D6.^2))/length(D6);

Total=POWER_DELTA+ POWER_THETA+POWER_ALPHA+POWER_BETA;

RELATIVE_DELTA=POWER_DELTA/Total;

RELATIVE_THETA=POWER_THETA/Total;

RELATIVE_ALPHA=POWER_ALPHA/Total;

RELATIVE_BETA=POWER_BETA/Total;

%**************End of Code

Here are my results versus the results I should achieve:

                             Old results                 My results

Relative_delta      0.602487293           0.572298897

Relative_theta      0.187303504           0.196419823

Relative_alpha     0.112981588           0.132041017

Relative_beta       0.073902161           0.099240263

I want to perform short time Fourier transform using python on an EEG dataset. I couldn't find any code related to that, if anyone could help please share any python code.

Hello Sleep and EEG researchers,

I am very new to the field of EEG analysis, but am beginning a clinical trial wherein we will use an EEG device to monitor sleep onset. Our instrument (BioGraph Infiniti from Thought Technologies) exports our raw data as a text file. I am wondering:

(1) Does anyone know of sleep analysts who can read or will accept text files?

(2) Does anyone know how to convert text files to EDF format?

(3) If I have to purchase a new device and software, what are your recommendations on quality and affordable EEG devices capable of measuring sleep?

Thank you so much in advance!

I am working on project epilepsy detector using EEG signal. But i failed to decompose EEG signal in EDF format.I will be thankful to him who provide MNE code or any suggestion.
