Example SimArray summary report. The report is generated after the second run of SimArray and includes a summary of the user-specified design decisions, estimated print run time, estimated maximum meta-grid area, and the randomised source visit map. The source visit map can be either comma,- tab- or space-delimited (default). In this example, and in Figure 8, the design requirement was to print 4 × copies of the exogenous spike control source visits (orange), 1 copy of each transcript-specific probe source visit (green), and omit the empty wells. This report was generated whilst simulating printing by a MicroGrid II 610 robotic spotter (Genomic Solutions). This figure has been colour-coded to aid comparison with Figures 6 and 8.
