Alignment Conservation Annotation
-This is an automatically calculated quantitative alignment
-annotation which measures the number of conserved physico-chemical
-properties conserved for each column of the alignment. Its calculation
-is based on the one used in
- the AMAS method of multiple sequence alignment analysis :
-
Conservation is measured as a numerical index reflecting the conservation of - physico-chemical - properties in the alignment: Identities score highest, and the next most - conserved group contain substitutions to amino acids lying in the same physico-chemical - class.
-Conservation is visualised on the alignment or a sequence group - as a histogram giving the score for each column. Conserved columns are - indicated by '*' (score of 11 with default amino acid property - grouping), and columns with mutations where all properties are - conserved are marked with a '+' (score of 10, indicating all - properties are conserved).
- -Colouring an alignment by conservation
-Conservation scores can be used to colour an alignment. This is
-explained further in the help page for conservation colouring.

++ Mousing over a conservation histogram reveals a tooltip which + contains a series of symbols corresponding to the physicochemical + properties that are conserved amongst the amino acids observed at + each position. In these tooltips, the presence of ! implies + that the lack of a particular physicochemical property is conserved + (e.g. !proline). +

If sequence groups have

+ result in Conservation being calculated for each group, as well as
+ the alignment as a whole.
