A project I’ve been working on for the last two months is finally online in beta form – check out
It’s essentially a biological alignment viewer for RNA sequences. Here’s a couple of screen shots:
2D Structure Viewer
2D Circle relationship Viewer
You can download the source code from the above link to play with it – it’s a MVVM implementation and has quite a bit of interesting optimizations in it for performance purposes, including a read-only data virtualization for large sequence manipulation. The next release will include a full read/write implementation so watch the project if you are interested!
