the GDT. They are all nearly identical, but a few entries change depending on the running process. You can see the layout of the Linux GDT in segment.h and its instantiation is here. There are four primary GDT entries: two flat ones for code and
GDT detects global, as opposed to local, similarity. Using GDT we focus on distance rather than RMSD. . an optimal method for finding the 'best super-position', which will minimize the distances between all selected residues, is not known. Results can only be approximated. So to find the 'best' global structural match, GDT uses many .
