155 open guide bug?

Is there an error in the guides for 155 global open? There's the backbone guide, and the grey sidechain guide, and they dont seem to be agreeing at the res #1 end. Using the backbone guide to rebuild that res #1 end, then taking the sidechain grey shadows as an indicator, there seems to be a one residue difference in the placement of where the sidechains should be. 12-Val is easily placed, shadow matching the sidechain guide. But the next available hydrophobe, 16-Phe, seems to be one entire residue out in the side chain guide, which causes all kinds of ridiculous consequences. Am I making sense, or do I need a holiday???

First, I made the assumption that you meant Val #16 and Phe #12 rather than the other way around. While it's true that the guide for these two residues is almost an exact match in my structure with a score of 10632, I do admit that rebuilding the N-terminus (#1 end) of that puzzle took me quite a while on Day 1. In particular, it involved temporarily setting the 10-17 helix to loops and straightening the 5-6 sheet (in fact I set 4 and 7 to sheet as well) followed by rebuilding the 10-17 helix manually (i.e. freezing off the rest of the protein and using bands to set the location of each residue manually, followed by setting the band strength to 10 via a recipe and then wiggling).

==> You might lose a lot of points in the process, but once that N-terminus is corrected, the rest of the protein is easy…
