#### Steps to Reproduce

I have not heard back on this issue yet. Our current workaround is manually adding a DIN event to each file.

Hi All,

I'm experiencing the same issue, and it looks like there are no new updates. It appears that a workaround solution is adding a DIN event to the file...how is this done in Netstation? Many thanks in advance. I suppose I could always convert to a .mat file and import the good 'ole fashioned way, but I would like to utilize the .mff plugin.

Thanks,

J

Hi there,

You can open the file in NetStation Review. Create a new set of events "EEGStart" and "EEGStop" or anything to your liking. Place the cursor at the start and end of your data and click on these markers from the Events pane. That's how I do it.

Hope it helps.

Hi R,

I can only find 2.01 version of the plug-in on the sccn website here: https://sccn.ucsd.edu/wiki/Plugin_list_all. Is there any other link where the plug-in is available?

Thanks!

Hi Dung,

I followed this link and tried downloading the updated plug-in. But it shows this error: The requested URL /eeglab/plugins//eeglab/plugin_uploader/uploaded_files/mffmatlabio2.02.zip was not found on this server.

Thank you for quick response!
