Selection
The recipe only proposes designs where there is a reasonable amount of sheets for each helix (minimum 2 sheets per helix) and a reasonable core potential. Only exact matching of above preferences are proposed, unless for very common structure (e.g. SSHSS), where a solution with extra loops could be proposed (up to 5 loops around an helix). The SS is archived in note 19. It can be recovered at any time using Reset my SS in note 19 _GS.

User guide for further design
1) On a reset of the puzzle, run the recipe and select to design you like (e.g. SHS, 2 sheets and one crossing helix) Now it's time to hand fold (did you expect to escape hand fold ?!?) 2) tool "Ideal SS" on each helix 3) You might freeze all helices and sheets if you want to use bands 4) Cut in the loops - or use bands - in order to align the sheets and make H-bonds 5) Align the helices along the sheets 6) Quickfix

1.1.0
ver 1.0.11 corrected the length of sheets in order to respect chirality in 85 + test bands

2.2.1
added soms SS. Freeze the nice structures and loops. Add bands between sheets. Clashing importance to 0.1, wiggle backbones until most sheet loops are ideal (check the filter ideal loop to see on screen). Use remix to try to fix unideal loops. If it does not work, add or delete residues in the loop and try again. If it doesn't work, Autostructure and try again. CI 1, mutate all. Wiggle all.Mutate all. Shake all. If there remain unideal loops, delete of add segments, remix, autostrucure, try again or run Find Starting Filter recipe if you have no time.

2.3
Adapted for binder designs (only set SS for unlocked segments if unlocked are on last segments)

thanks for sharing
Thanks Bruno :) This is much better than our old starter recipes which didn't address ideal loops at all

2.3.1
Adapted to most common Blueprint shapes (3 loops around helices). Less loops around helices give non-parallel structures, which is less likely to be ok for monomer core filter. When I try something that immediately fits exactly the filters constraints for monomer core and ideal loops, I add an "ok bp" as a comment within the recipe (this can be usefull for future updates, e.g. indicating "ok bp" in the dialog when appropriate). It only works curently for number of residues as multiple of 5. For lengths in the between, user could edit the recipe and copy the proxy SS into text editor then adapt and use recipe SS Edit or AA Copy Paste Compare in order to input the SS into the puzzle.

love it. I tried all of them
love it. I tried all of them against covid 15 and HSSSSH would shake and wiggle right into a desired shape (all of the sheets eventually bonded nicely w/o any pulling on my part.) And it scored rather high w/ no intervention. It makes me wonder what was so special about that pattern that would lend it to naturally going into a shape I would imagine. And it would also be nice to throw many others in to see how they'd perform. HSSHSSH I also try to play with shapes like a Greek Key Motif https://en.wikipedia.org/wiki/Structural_motif and to see what it scores like

thanks for the suggestions
I actually designed the most common ones as seen in Foldit top results for design puzzles (not for design binding puzzles). It would be great to test other shapes for the binding puzzles. I tested HHHHHH with some good result but no top result, so I abandonned this idea of small helice binding into the site. I don't remember HSSHSSH in top results for simple designs. How to name the Greek Key and make it understandable for user? What do you think about S-SSSHH, HHS-SSS etc ? (I suppose that adding 2 helices is necessary for monomer core). The problem (or the advantage for binding ?) of the Greek Key might be the long loop.

I am not sure how to name the
I am not sure how to name the Greek key with the current naming convention. It woud be nice to have some hint, though, that it is intended for it. S-SSSHH (greekKey) or S-SSSHH (GK).

One thing
I think having a loop at the end of your beginning or end sheet is not a good idea. It is very hard to get ideal loops because Foldit thinks the loop is a sheet and wants it to bond to the sheet next to it.

I don't know
I would need the advice of a scientist. I've the impression that top solutions have loop at ends.

2.3.3
Automatic ideal SS at end of process. Now what you still need to do: -use Blue Print in order to idealize the loops |
|
(edited) The proposed SS is based on following basic preferences:
-1 loop at each end
-2, 4 or 5 loops between sheets (SS)
-3 loops between helixes (HH), and between helix and sheet (HS)
-helix length = 2 * sheet length
