Load EEG data

Post by WeBrainTool » Mon May 24, 2021 9:18 pm

EEGLAB functions (based on eeglab14_1_0b) are used to load various EEG data. Currently, supporting EEG data format are:

EEGLAB .set File (recommended)
The function is ‘pop_importdata()’. It supports reading the EEGLAB dataset files (.set).

ASCII/Float .txt File or MATLAB .mat/.dat File
The function is ‘pop_importdata()’. When reading a MATLAB .mat file, please confirm that it must contain only one MATLAB variable (channels × time points). When reading a ASCII .txt file, please confirm that is must contain only EEG data with channels × time points. If your data are .txt or .mat files, sampling rate must be filled in the parameter box when using some EEG tools. It is suggested to use DRT tool (https://webrain.uestc.edu.cn/) to convert EEG data to EEGLAB .set files, by writing sampling rate and channel locations.

Curry 6/7 .dat File
The function is ‘pop_loadcurry()’. It supports reading NeuroScan Curry6/7 continuous EEG data files (.dat, .dap and .rs3).

Curry 8 .cdt File
The function is ‘pop_loadcurry()’. It supports reading NeuroScan Curry8 continuous EEG data files (.cdt, .cdt.ceo and .cdt.dpa).

NeuroScan .cnt File
The function is ‘pop_loadcnt()’. It supports reading NeuroScan EEG data files (.cnt). Data format 16bit or 32bit will be auto-detected.

NeuroScan .eeg File
The function is ‘pop_loadeeg()’. It supports reading the NeuroScan EEG data files (.eeg). If the .eeg file is epoched data (channels × time points × trials), some tools may be not available.

Biosemi .bdf/.edf File
The function is ‘pop_readbdf()’. Based on Biosemi functions, it supports reading 16-bit European standard "EDF" (European Data Format) and 24-bit BDF (Biosemi Data Format).

Brain Vis. Rec. .vhdr File
The function is ‘pop_loadbv()’. It supports reading Brain Vision Analyzer data files (.dat, .vhdr and .vmrk).
