[Feature Request] Support for importing Neuroscan MEG (.dat) files

[jade-l228]

Dear Brainstorm Team,

I am a university professor, and our institution has recently purchased a MEG system from Neuroscan. We are currently in the process of establishing a data analysis workflow and would like to use Brainstorm as the main analysis software.

However, the MEG data from the Neuroscan system is saved in .dat format, and it seems that Brainstorm does not currently support this type of file. We have tried importing it through various options in the GUI, but none succeeded.

I would like to ask:

• Is there any current way to import .dat files from Neuroscan MEG systems into Brainstorm?
• If not, would the development team consider adding this compatibility in future versions?
• We are happy to provide sample data files to help with testing and development, if needed.

We would greatly appreciate your support, as Brainstorm would be a valuable tool for both our research and teaching purposes.

Thank you for your time!

Best regards, Jade

Thank you very much for your reply. I apologize for the delay in getting back to you. Attached is the MEG data for the P1 component that we collected,

and we hope it will be helpful. We are all looking forward to using Brainstorm to analyze this type of data. Thank you again.  

Regards, Jade

@jade-l228, the second and first links are the same and they do not work

[jade-l228]

Sorry, may I ask what kind of transmission method we should use for you to open it? We have checked that this Dropbox link is accessible, and we also use it for transmission and communication with foreign parties.

Thanks, Jade
