If you can't sequence it by examining the density then the following
likely apply:
You won't be able to tell from Rfree anyway.
You probably won't be able to get an unambiguous answer from real
space correlation.
I thought there would be more, but that's about it. Your best bet is
to care
In an isolated piece of density, I want to fit a 7AA peptide fragment from a
protein.
Only the sequence of the whole protein (200AA) is known, and I don't know the
peptide sequence.
I think it's best to try from the beginning of the whole sequence to the end.
So is there any software or scripts w
