the basis to calculate a score for an alignment and thus the
method of generating optimised alignments. The equivalence
scores usually indicate how readily different residue types
substitute for one another.
With reference to object-oriented programming, a superclass is
a type of object definition that lends its specification as the basis
for another kind of object (a subclass).
A type of machine learning method where the pattern-matching
algorithm is trained to associating known inputs with known
outputs so that afterwards it may make predictions in a general
way on unseen data. See also training below.
With regard to machine learning, one of the data points
considered by a support vector machine that lies on the edge of,
and thus defines, the boundary used in the separation of data
classes.
A kind of machine learning algorithm that works by performing
a linear separation of data mapped into a space of higher
dimensionality, using the kernel trick. The widest margin region
between different data classes is found in a regression-like
process, which defines a decision boundary that can be used to
separate unseen data points in a general way. This separation
margin is defined by the support vectors (see above) and is less
susceptible to over-training compared to methods like artificial
neural networks.
Using support vector machines to approximate continuous
functions, e.g. to predict where points lie on a graph. This is in
contrast to using support vector machines to classify data points
into discrete categories.
The study of the emergent properties of a biological system
considered as a whole, i.e. things that would not be evident by
looking at individual components in isolation.
Derived from a ‘tab stop’ on a typewriter. A tab is a key on the
keyboard and the resulting special (whitespace) character that
causes indentation of text. A tab is often longer than several

normal spaces.
Relational databases store data in tables, with each column
representing an attribute of the data and each row representing
one record of data. This a similar notion to the usage of tables in
spreadsheets.
The ability of certain chemical compounds to be able to swap
between two different forms that contain the same atoms. Often
this involves an equilibrium where both chemical structures are
present to some degree and continuously inter-convert.
The different hierarchical classifications of organisms within the
evolutionary tree of life, i.e. the named groups of related
organisms.
When referring to nucleic acid strands the template is the strand
that is the basis for the creation of a new strand using base-
pairing rules, for example in DNA and RNA synthesis.
With specific reference to protein structures, a template is a
protein of known (experimentally determined) structure which
is used as the basis for predicting the structure of another similar
protein: generally a homologue with a similar sequence.
A sequence of the smallest segments of program instructions
that can be scheduled to run independently on a computer. The
notion behind this is that a processor’s stream of execution can
rapidly switch between different computing tasks. A result is
that multiple programs can effectively be run at the same time
on a single processor, though on a small scale the execution may
merely be interlaced. Threading is a concept distinct from true
parallel processing, which uses separate processor cores, though
most modern multi-core processors implement both concepts.
A specified time that is allowed to elapse before a specific event
is triggered, often used as a failsafe in the case that various
asynchronous tasks do not complete in a reasonable time.
A string of one or more characters that when taken together
