The publisher of The Journal of Cell Biology has released an application for sharing biological image data associated with published research called the JCB DataViewer. The viewer not only permits sharing of original image files, but also allows viewers to perform simple analyses of the images. The video above shows how users can analyze the images online. The application was created through a collaboration between The Journal of Cell Biology, Xpresstrack, and Glencoe Software using open source technology developed by the Open Microscopy Environment.
