M has 6 instead of expected 5 sidechain atoms. 258 H has 5 instead of expected 4 sidechain atoms. Residue TYR 36 has 9 instead of expected 8 sidechain atoms. The output from DSSP on file myprotein.dssp contains secondary structure assignments and other information, one line per residue. 36 98C 6 Line length of output is 13x characters.
Lines end in a number or a period.
Not used for structure definition. Also, atom OXT of c-terminal residues is treated like a side chain atom if it is listed as part of the last residue. Unknown or unusual residues are named X on output and are not checked for standard number of sidechain atoms. All explicit water molecules, like other hetatoms, are ignored.
