-### Predicting Proteins with Chemical Modifications or Non-Carnonical Amino Acids
+### Predicting Proteins with Chemical Modifications or Non-Canonical Amino Acids
 To predict proteins with chemically modified residues or non-canonical amino acids, you can use residue replacement. This involves replacing the chemically modified residue or NCAA with a small molecule file that defines the structure of the modified residue. Here is an example of predicting a phosphorylated protein structure. (from `rf2aa/config/inference/residue_replacement.yaml`)
