This article mainly explains the "installation, configuration and testing methods of FieldTrip toolbox". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "the installation, configuration and testing methods of FieldTrip toolbox".

FieldTrip is the MATLAB software toolkit for MEG, EEG, iEEG and NIRS analysis. It provides preprocessing and advanced analysis methods, such as time-frequency analysis, source reconstruction using dipoles, distributed sources and beamformer, and nonparametric statistical testing.

download

First of all, download the corresponding software tools, the URL is as follows (you need to fill in the relevant information). For convenience, the community has downloaded the software and replied "FT" in the background to obtain the FieldTrip tool.

Http://www.fieldtriptoolbox.org/download.php

After downloading, you can decompress it directly, and then copy the folder to toolbox in matlab, as shown below:

Configuration path

Open Matlab and find the setting path in the home page

Click to add folder

Just select fieldtrip.

Finally, just click Save.

test

The test data here is SubjectEEG.zip. After decompression, it is as follows:

Data Abstract: Irina Siminova obtained the EEG data set SubjectEEG.zip in a study of semantic processing of stimuli represented by pictures, visual text, or auditory words. A 64-channel brain product EEG amplifier was used. 60 scalp electrodes were placed in the electrode cap, one of which was placed under the right eye to obtain data. After collection, the re-reference calculation signals "EOGv" and "EOGh" are used. In the process of acquisition, all channels take the left mastoid as a reference, and an electrode is placed at the earlobe as a grounding. Channels 1-60 correspond to electrodes located at the head, except for channels 53 located at the right mastoid. Channels 61, 62, 63 are not connected to the electrode at all. Channel 64 is connected to the electrode located below the left eye. So we have 62 channels of interest: 60 from head + eogh + eogv.

Test the code:

Cfg = []; cfg.dataset = 'subj2.vhdr';data_eeg = ft_preprocessing (cfg)

Chansel = 1 legend plot (data_eeg.time {1}, data_eeg.trial {1} (chansel,:) xlabel ('time (s)') ylabel ('channel amplitude (uV)') legend (data_eeg.label (chansel))

Test results:

Indicates that the installation is successful and the configuration is successful!
