NS : Total number of residues in Structure (rotated structure)
NT : Total number of residues in TARGET (frame of reference)
N : Total number of residues superimposed under 4.0 Angstrom distance cutoff
RMSD : RMS deviation calculated on all N residues superimposed under 4.0 Angstrom distance cutoff
Seq_Id : Sequence Identity. Percent of identical residues from the total of N aligned.
LGA_S : Structure similarity score calculated by internal LGA procedure (see LGA paper for details)
LGA_Q : Score (how tight is the superposition) calculated by the formula: Q = 0.1*N/(0.1+RMSD)
PLOTS : T - Flat text file (output from LGA program, rotated structure)
PLOTS : P - Plot of superimposed structures (3D plot colored as bars)
