A method of calibrating a measurement of electromagnetic signals. The system includes a microfabricated substrate having an enrichment channel to prepare an enriched cell sample from the cell-containing liquid. Each matrix corresponds to one key process area, and each of the key process areas includes different goals for assessing implementation of the MSOC. Some embodiments are implemented in a video editing application that has a user selectable alignment operation, which when selected aligns two or more video sequences.
