Description

CASP ROLL started up again, but this is the first target that isn't too large for Foldit. We are giving you the 5 Rosetta Server models to work on. Resetting the puzzle will cycle through them, please try out all 5 starting points. The secondary structure predictions are provided on the extended chain in the Alignment Tool, with more details posted in the puzzle comments.

Here is the CASP link for this target (showing the amino acid sequence):
http://predictioncenter.org/casprol/target.cgi?id=78

Here is the sequence logo predicted by the SAM server.

H = helix
E = sheet
C = loop (or coil)

The taller the letter at each position, the higher the probability of that specific secondary structure for that amino acid.

For example, the Valines at residues 18, 54, 79 and 100 is highly predicted to be part of a helix. However, the Valine at residue 111 is not predicted to be anything!

The above predictions are already on the starting extended chain which is available in the Alignment Tool (based on the horizontal lines in the above figure).

The puzzle information states: "this round only GUI scripts are allowed." This is not correct I am seeing regular LUA scripts run just fine.

Because the Rosetta Server models do not match the secondary structure predictions, I did not want to bias you with Rosetta's structure.

The extended chain is only available in the alignment tool (for those who want it) but I did not want some players to randomly start with the extended chain if they didn't know they could reset to get a better model.
This is how we normally post CASP ROLL puzzles starting from Server Models (Puzzle 654, for example).
The extended chain does have the secondary structure predictions on it, however.

Thanks you gramps for providing that script for everyone!

I'm very sorry about that marie_s, I checked this before posting it, but clearly this isn't working correctly!

I'll look into what is going on, thankfully everyone can use gramps' script for now (good thing this wasn't a GUI-only round!)
