TM-score is a measure of global structural similarity between query and template protein.
RMSD^a is the RMSD between residues that are structurally aligned by TM-align.
IDEN^a is the percentage sequence identity in the structurally aligned region.
Cov. represents the coverage of the alignment by TM-align and is equal to the number of structurally aligned residues divided by length of the query protein.
