When using the Xenbase gene expression search we felt it would be most valuable if high quality images appeared near the top of your search results. That is why we have developed a way to allow Xenbase users to vote on the quality of an image. You can change your vote for a given image as many times as you want, but only your last vote is counted. Additionally,we've provided a comment box if you want to tell us why you think a specific image is good or bad.
As you can see above, this information box will tell you how people have voted on the image you are currently looking at. It is important to note that all of your votes are completely anonymous.
