<p class="MsoNormal">I’ve just started working with Measure Projection and keep bumping into an error related to concatenation and the size of the matrices. It occurs whether I try to project ERP, ERSP or Spec. I have precomputed both channel and component
measures and am wondering if the error is due to a precomputing step that might have reduced the size of my dataset for some subjects/conditions and not others? The error is as follows:</p>
