I have carried out EEG epoching and source localization using non-MNE means. Now I wish to import said data for visualization. For the source localization, I referenced the Desikan-Killiany Atlas, setting each section as a source coordinate and using that for source analyzing the raw data. Is there a way to import and visualize the source data in this format?

Hello, could you please be more specific on what **exactly** you have and what **exactly** you want to do?

Using the Desikan-Killiany Atlas, I created a source space where each source point corresponds to a section in the Atlas. Then, I took a raw EEG file, prepared it into epochs, and souce localized it without using MNE. Then, I calculated the PSD values for each souce point. What I wish to do is either

1. Import the source localized data I prepared into MNE so that I can use the methods there to visualize. More specifically, visualize in a similar way to stc.plot() to display a 3D image of the brain using the fs\_average MRI as template.

2. Using MNE, import the raw file, then preprocess and source localize it to the source points I defined with the Desikan-Killiany Atlas. Then calculate the PSD and visualize it.
