Generally scores below 0.20 corresponds to randomly chosen unrelated proteins whereas structures with a score higher than 0.5 assume roughly the same fold. [2] A quantitative study [3] shows that proteins of TM-score = 0.5 have a posterior probability of 37% in the same CATH topology family and of 13% in the same SCOP fold family. The ...
In bioinformatics, the BLOSUM (BLOcks SUbstitution Matrix) matrix is a substitution matrix used for sequence alignment of proteins. BLOSUM matrices are used to score alignments between evolutionarily divergent protein sequences. They are based on local alignments.
The score is greater than 0 if it is more likely to be a functional site than a random site, and less than 0 if it is more likely to be a random site than a functional site. [1] The sequence score can also be interpreted in a physical framework as the binding energy for that sequence.
Phenyx is a sequence database search engine developed by Geneva Bioinformatics (GeneBio) in collaboration with the Swiss Institute of Bioinformatics (SIB). Phenyx incorporates OLAV, a family of statistical scoring models, to generate and optimize scoring schemes that can be tailored for all kinds of instruments, instrumental set-ups and general ...
ANOVA–simultaneous component analysis (ASCA or ANOVA-SCA) is a statistical technique used to analyze complex datasets, particularly those arising from designed experiments with multiple factor s, notably in the fields of computational biology and bioinformatics.
Phred quality scores shown on a DNA sequence trace. A Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing. [1] [2] It was originally developed for the computer program Phred to help in the automation of DNA sequencing in the Human Genome Project.

Scoring functions are widely used in drug discovery and other molecular modelling applications. These include: [4] Virtual screening of small molecule databases of candidate ligands to identify novel small molecules that bind to a protein target of interest and therefore are useful starting points for drug discovery [5]
