When using Blueprint, the residues are indexed as 1, 2, 3… To find a residue’s index, press Tab while hovering over a residue. This also shows more detailed information like what amino acid it is and a breakdown of how it’s scoring and why.

Today’s Master Folding Tips
Having trouble with your loops? Here’s a thread from the past if you want to get into some of the nitty-gritty, but some of the takeaways are: use freeze or cutpoints to isolate your loop, mutate everything to glycine (the one with no sidechain at all), and use the Rama map by finding those sidechains and dragging them into a colored region. Still having trouble? Post a screenshot to our Discord to get some help!

When you feel like you’re just moving spaghetti around, take a moment to pause and set a goal for yourself. Maybe you want your helices to look more straight, or your sheets to line up better. Set subgoals to work toward instead of vaguely wiggling toward a higher score. More often than not, you need to ignore your score for a while until your protein looks ready for polish!
