<div dir="ltr">When you do `stc = read_source_estimate(...)`, it will automatically load both left and right hemisphere files. So passing in a `-lh.stc` filename will give the same SourceEstimate object as passing in a `-rh.stc` filename. You probably want to look at e.g. `stc.lh_data` or `stc.rh_data`.<div><br></div><div>Eric</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 23, 2015 at 8:02 AM, Scott Marek <span dir="ltr"><<a href="mailto:smarek0502@gmail.com" target="_blank">smarek0502@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>Hi,<br><br></div>I am trying to do source projection for both right and left hemisphere dipoles, first without using a label file.<br><br>fname_inv = subjects_dir + '/' + s + '/MEG/' + s + '_rest_fwd.fif-meg-inv.fif'<br>inverse_operator = read_inverse_operator(fname_inv)<br><br>stc = apply_inverse_raw(raw,inverse_operator,lambda2,method='MNE',label=None,start=1,stop=None) <br><br><br></div><div>The issue I am having is that the left and right hemisphere stc files are equivalent.
