Average score regressions as a function of domain length weighted by length frequencies.

The first column identifies the test: “high” means with scores above the average ( for PD and for TM); TM-PD means that PD-scores are calculated for the alignments done by TM-align; 1 or 2 means the first or second domain length, respectively; “symm” means taking a symmetrical score. The second column is the length coefficient multiplied by 1000, so it is the average score variation for 1000 amino acids. The third column is the adjusted . We can see in bold all the tests with a significant linear dependency (i.e., adj. above 0.5).
