From a link in the article: http://scienceblog.cancerresearchuk.org/2013/03/01/can-the-p...

> Take these results from a microarray below: the pink horizontal band is, effectively, the length of a chromosome – and any peaks indicate extra copies of that particular region.

> There are four regions where you can see the levels change – these show where alterations have occurred in a specific part of the genome. But to be able to home in exactly on which genes are affected, and identify those that may play a key role in cancer, our scientists need to know precisely where this shift begins and ends – and for this we need the accuracy of the human eye.

It sounds like this game is built on the idea the human eye is somehow better at detecting peaks in a signal than a computer, which doesn't make any sense to me.

Can someone explain what's actually being gained from the human component here besides good PR?
