Convert .poly5 to .mat or any readable dataset for brainstorm

[Mahamc]

Hello,

I am having trouble using my datasets in Brainstorm and I have been advised to convert them from .poly5 to either .mat or something that would work for Brainstorm. After spending few days on it, I still am struggling on converting those.
Does anyone know how to do it ?

Unable to import the data with correct time

Thanks for your response. Our original files is (.Poly5) and this files was not included in the brainstrom menu. When I used ASCII format to read the data, it would cost a lot of time and couldn't read it, so I used the Matlab code to change this file (.Poly 5) into EEGlab files (.set). In EEGlab, the sampling frequency set to 1000 Hz, so I didn't know why the sampling frequency would turn into 1000000Hz in brainstorm. Is there any method could change the sampling frequency in brainstorm? Thank…

Hello,
thank you for your response.
However, I already tried this and it did not help.

Hi @Mahamc,

• Can you describe what is the things that you have tried?
• Where is the file coming from? A SAGA 32/64+ device?
  • If so, have you converted the .ploy5 to EEGLAB set using their provided tools?
