Not a valid Nihon Kohden EEG file

Hi!
I just opened a new problem on github.

Also, as you asked me, I uploaded the file

raw = mne.io.read_raw_nihon('DA0935FF.EEG')  #lê o arquivo
print(raw.info)  #printa informações sobre o arquivo
# raw.crop(20).load_data()

---------------------------------------------------------------------------

Hi @21012015 I assume that you are talking about this comment you made in the thread about MNE-Python’s Nihon Kohden reader?

If you read the thread you’ll see that we need somebody to add support for new versions of the file format to the reader software, and so far nobody has had the time. As discussed in that thread, one could get the inspiration from the Brainstorm software, if one asked them nicely for license permissions.

Maybe for a pragmatic solution @BarryLiu97 can expand on what he meant with his comment:

Hi, as I know, Neuro Workbench supports convert EEG files to EDF format.

Though I would prefer that they edit their original comment in the GitHub thread and we keep this present (discourse thread) limited, as it (currently) seems like a duplicate.
