ASAD is A Sequence Attribute Display tool. It is written as a set of Microsoft
Excel macros. There is one base per cell and it builds on the familiar Excel
interface to allow for the flexible and efficient display of attributes
(hydrophobicity etc.) using similar colours and styles for one sequence or
multiple aligned sequences. It provides tools which enable the user to quickly
load a set of sequence(s) and using a user definable set of styles and base
attribute values, display all bases in similar styles that have similar
attribute values. The visual highlighting assists in manual evaluation of
similarity between sequences or parts of the one sequence. Tools allow for
making insertions or deletions, creating a consensus sequence, finding
identical sequences (useful with large numbers of short sequences),
graphing defined attributes along a sequence, calculating basic statistics
either horizontally or vertically and changing the number of bases per
line. ASAD can be accessed freely at
