importing and displaying BrainVision format files
Posted: Fri May 26, 2023 11:38 pm
This is my first forum post. I hope I am placing it in the correct place. Here is my situation:
I have a 28 subject EEG dataset collected using NeuroScan hardware, saved in their CNT format. Using EEGlab I converted this set into BrainVision format (.dat, .vhrd, .vmrk) format. I then used the BrainVision Format file reader box in OpenViBE to open the BV format files. When I try to display them, though, I get flat lines. I do not see where I can control the display scale. I need to verify the data looks OK before proceeding with my next steps.
I want to use this dataset to train an SVM classifier in OpenViBE and make sure I can get it working satisfactorily before collecting our own EEG data using the BV LiveAmp system we have purchased recently for this purpose.
I have gone through some of the tutorial material and can successfully load example .OV files and run the demos with the EEG data in them. Might I have to convert the BV format files to .OV file format before I can do that?
This is a critical pathway in our project now.
