9 men’s water polo team, 3 women’s soccer and 1 men’s basketball). The forward model obtained as below: Powered by Discourse, best viewed with JavaScript enabled, https://neuroimage.usc.edu/brainstorm/Tutorials/TimeFrequency#Scouts.
github.com No, if correct your leadfield matrix elements should have a magnitude of more or less this. Why?? Dear experts Hi I'm going to know what is the relation between the scout vertices and the brain grid. how can I do that? I don't know why you use the conv function, since it is a direct multiplication with your source signal (Measurement = LF*Sources). where am I wrong? however, it took a lot of time and the AEC matrix was 639x639. I can see the communications background, in which you would convolve using an impulse response. Dear Steven,

I searched on Brainstorm's tutorials and discussions to find the relation between grid point arrays and forward model arrays. When I check the GridLoc arrays, their values are not related to scouts' location values (54_135_120)! I didn't select scouts on the cortex surface, they selected in the whole of the brain volume so what is the relation between scouts and brain grid? And the Trojans aren't just sitting on the sidelines waiting.

4.simulate recording from sources drop down list It should be OK. Hosted by Erik McKinney and the WeAreSC staff. First of all, thank you for your reply, It was done. is it right?

Different source orientations and depth have different sensitivities to EEG. USC recruiting roundup: Two tackles off the table, RB recruiting, 2022 check-ins, 2022 safety Kamari Ramsey likes what he's seen from USC defensive staff, Trojans in Top 10 for Texas offensive tackle, (You must log in or sign up to post here. "54_135_120" is not the "scout location", it's the scout name. This file has been truncated. also, I've calculated a leadfeild matrix by openMEEG BEM by 15002 grid points. I did all the things you suggested but the results are different from BrainStorm results. Get the latest USC Football news, photos, rankings, lists and more on Bleacher Report I was trying to compute Amplitude Envelope Correlation at source level on selected scouts from atlas, I just selected 2 scouts (Right and Left Precuneus), so I thought It would be a simple calculation (1X1),

% therefore I export simulated signals to Matlab and convolve them by the Gain matrix columns that are related to scouts center. USC’s quarterback depth chart has been thinned out over the past year, but the Trojans added another future signal-caller to … Continue Reading » Sep 19, 2020 Erik McKinney. The leadfield matrix is in the order of #electrodes*(3*#sourcepoints), in your case 64*(3 * 15670), if it is unconstrained. If you are using a surface source model with constrained orientations, use preferably the Vertices field from the surface file. Use larger scouts for your simulations, so that for each source you have various source orientations and depth I think that 7 scout vertices should be related to brain grid points. Simulate scalp recording Discussions In this case however you can see it as a static gain. Let me give a better description of my problem; Thanks in advance!
but nothing happens after step 4, the software does not response.
