<p><b>Problems:</b> This works well for fixed samples, but what about live samples? With the current difficulties, we are not prepared to apply MicroMaps logic to motile samples. Moving samples are infeasible with current processing delays. For now, we recommend using the <a href="//2015.igem.org/Team:Cambridge-JIC/Webshell" class="blue">WebShell</a>. We are still working on this issue, expect the potential fix in MicroMaps Version 2. Made some progress with an image tracking challenge: each of our software team was challenged to track some moving pixels in an image ***(ants.gif) to find the hidden message, Will's entry shown in bants.gif***. Perhaps in V.2 interesting live features (eg. moving cells) will be automatically tracked.</p> | <p><b>Problems:</b> This works well for fixed samples, but what about live samples?
