Hello Everyone

I have a question about structure for connectivity analysis on sources.

My goal:

  • preprocess and cut data into trials
  • create headmodels, using template MRI file
  • perform source analysis using lcmv, but not on averaged trial data, i want to to this on each trial separately
  • parcel the reconstucted source data onto atlas, im specifically interested in visual areas
  • create a matrix, which will contain structures from the atlas as rows and source data as columns.
  • perform connectivity analysis on parcellated data to atlas.
  • I've done most of the steps above, but i am stuck on performing source analysis and then parcellating the data to regions in atlas. My question is, is it possible to do source analysis on each trial separately, not on averaged data (since i do not have ERPs in my data)? And then, is it possible to parcellate this source data to atlas?

    If it is possible, i will be very grateful for any information how to make this work.

    I tried doing this in Matlab, but i had trouble with running source analysis on trial data, because it is really inefficient, and i got feedback that performing source analysis on each trial is not recommended, so i thought i will ask here - maybe there is better approach that I dont know about.

    I will be thankful for any help.

    Best regards, Monika
