Difficulty: Beginner
Description: In electron density puzzles, we give you some experimental data to help you find the correct fold. This data takes the form of an electron density, and appears in game as a guide. You can adjust the guide visualization by going to [Actions]>[Electron Density]. For players with fewer than 150 global points.


If you are new to Foldit, here are detailed instructions to get you started: http://fold.it/portal/node/988864

If you want to fold proteins, know that there are many ways to play and this variety is the main value of Foldit :
- try all puzzles not only "Beginners" ones,
- fold first the ones you like the most,
- try it by yourself to understand what works and what doesn't,
- ask for tips in global chat when you think you don't understand something.

Make sure you have followed these tutorials:
- Lonely Sheets,
- Lock and Lower,
- Rebuild,
- Structure and Rebuild,
- Control over Clashing,
and especially:
- Electron Density
before starting this puzzle.

After you have downloaded and installed the Foldit game client, run it and log in with your user name and password with the "Play Online" button.

The beginner puzzles will be under the "Science Puzzles" section. You may need to click the checkbox before the "Show beginner puzzles" so that the beginner puzzles will show up the list. Scroll to find the one you want, and click "play".

See also http://fold.it/portal/node/988864 for more information for beginners, and be sure to check out the tutorials for more information on how to play the game. If you need help using Foldit in general (rather than comments and questions about a puzzle in particular), try posting in the forum. Other Foldit users hang out there and can give you advice.

Crashes the Linux client

On Linux, this puzzle crashes Foldit when I start to wiggle or shake, it says

terminate called after throwing an instance of 'std::bad_alloc'
