Predicted contact puzzlesEdit

See the blog entry on Foldit site.

Example in exploration puzzleEdit

Ss1

You can bring up the in-game Contact Map by going to Actions > Contact Map or by clicking the panel above your score.


When you open the puzzle, you will notice the normal score panel at the top of the screen has an extra panel above it. This panel shows your normal Foldit score (Stability) and the exploration multiplier (along with a meter which shows you how close to the maximum multiplier you are). Clicking on this panel will open the Contact Map. You can also open it by going to Actions > Contact Map.



SC

Selected contacts from the Contact Panel show up on the 3D model of the protein.

We can select cells on the contact map by clicking on them with the mouse. This will draw lines between the segments. Red lines mean you don’t have a contact yet, and green means you do. In this case, we don’t have any contacts in these cells.




SD

Placing bands along the contact lines will help bring them closer.





A basic strategy is to put bands along the contact lines, and then wiggle. this will bring the segments closer and form a sheet.



SE

The bands brought the segments close enough to form contacts. You can see the contact lines turned green and the cells on the Contact Map now have black squares in them.



After wiggling, we can see how black squares appeared on the contact map around the region we selected, and the lines on the 3D model turned green.

You can press clear to clear the selected contacts.
