I recently got a .eeg file from a hospital, but I cannot read it by MNE-python. I noticed that the version (EEG-1200A V01.00) is not supported at this moment.
Can anyone help with this problem?

Can you read this file with another reader? just to make sure the file is not corrupted.

if so can you open an issue on github?


Yes, the file can be opened by Neuro Workbench which provided by nihon kohden. OK I will open an issue on github.
