perhaps we should just let the update happen and then discuss remaining score issues. There is presumably a necessary hiatus between devprev and main updates.
Evo scores may be affected or it may be a separate issue. Mike has posted on evo score problems here;
They're just making sure it doesn't crash, or that all helices score -1000 now, or something like that. If they did, you can be sure phi16 would give them an earful! The original plan was to shut down foldit for a day and make all puzzles end on the same day! I don't think either the players or the devs liked that much, so that's why we have the score glitch today.
Exactly… we appreciate everyone using "devprev" for today to make sure everything doesn't descend into chaos when we update this to "main" as well ;-)
If you can't stand having lower scores than other players today, feel free to switch from "devprev" to "main" but by tonight everyone will be on the same scoring system.
This is why we waited to do this until 548 closed yesterday, so that there would be no puzzles closing in the next 2 days.
Just an fyi, my solution doesn't even have a helix of any sort in it.
The entire game should have been shut down and everyone updated at the same time.
I know you are doing your best, but, I'm also assuming you want to know how this new rollout is working.
Just picked up a share with an unupdated client and didn't even have to evo it. It was created on an updated client and loaded much higher on the NON updated client. lol Will the scores on the current scoreboard also be wiped once all scoring is the same? If not, there is a huge scoring mess and none of the scores from the currently running puzzles will have any real value.
When the reverse happened and I ended up with a lower score, the scoreboard still showed the higher score.
To do that we would have had to either:
1) Have all the puzzles close at the same time (which nobody wants)
or
2) Not post any new puzzles until the last one closed (so for 1 week you'd have very few puzzles, and for a few days there would only be one puzzle up)
Again, everyone will be in the same boat tonight.
Alternatively we could make all the currently open puzzles worth 0 points.
I will not post the first CASP 10 puzzle until the new client gets posted to "main" so that everybody will have the exact same score function for the duration of that (and future) puzzles.
We do apologize for this, but we really had to post this fix (especially before CASP started), and we tried to warn everyone about it: http://fold.it/portal/node/992470
Thanks for your patience… I only wish we had dealt with this way back in the day when the pi-helix loophole was first uncovered by you guys.
It isn't only affecting pi helix scoring. The puzzle I first noticed the drop in score in doesn't have any helixes.
Here you go: http://en.wikipedia.org/wiki/Pi_helix
To make a long story short, it's a helix whose hydrogen bond pattern is "n to n+5" instead of "n to n+4" (as in the standard alpha helix). Such a structure would score unreasonably high previously because the hydrogen bonds in a pi helix would be mis-categorized under the Rosetta scoring function.
The only change is for "n to n+5" hydrogen bonds (as infjamc mentions below) so it will also alter the score of ANY structure that forms a backbone hydrogen bond with a residue 5 spots before (or after) it, even if it's not in a helix (such as a turn in a loop or something).
I know this is frustrating, I know it's a pain, but the Baker Lab has thoroughly benchmarked this score change (which is why it took this long to roll out to Foldit) and the new scoring is the correct scoring and how it should have behaved all along.
You all know that the Rosetta Energy Score function is far from perfect, and there are many people in the Baker Lab working on improving it, but this single change is at least going in the right direction and fixing one element that was wrong.
What time will the final changes be made? I'd like to have my recipes stopped.
And, thanks for all you do. I'm sure most, if not everyone appreciates all you do. ;)
