Multiple alignment program - interface to ClustalW program qualifiers for parameter: sequence Name of old dendrogram file Name of old dendrogram file Protein pairwise alignment matrix options The scoring table which describes the similarity of each amino acid to each other. There are three 'in-built' series of weight matrices offered. Each consists of several matrices which work differently at different evolutionary distances. To see the exact details, read the documentation. Crudely, we store several matrices in memory, spanning the full range of amino acid distance (from almost identical sequences to highly divergent ones). For very similar sequences, it is best to use a strict weight matrix which only gives a high score to identities and the most favoured conservative substitutions. For more divergent sequences, it is appropriate to use 'softer' matrices which give a high score to many other frequent substitutions. 1) BLOSUM (Henikoff). These matrices appear to be the best available for carrying out data base similarity (homology searches). The matrices used are: Blosum80, 62, 45 and 30. 2) PAM (Dayhoff). These have been extremely widely used since the late '70s. We use the PAM 120, 160, 250 and 350 matrices. 3) GONNET . These matrices were derived using almost the same procedure as the Dayhoff one (above) but are much more up to date and are based on a far larger data set. They appear to be more sensitive than the Dayhoff series. We use the GONNET 40, 80, 120, 160, 250 and 350 matrices. We also supply an identity matrix which gives a score of 1.0 to two identical amino acids and a score of zero otherwise. This matrix is not very useful. DNA pairwise alignment matrix options The scoring table which describes the scores assigned to matches and mismatches (including IUB ambiguity codes). Filename of user pairwise matrix Filename of user pairwise matrix Protein multiple alignment matrix options This gives a menu where you are offered a choice of weight matrices. The default for proteins is the PAM series derived by Gonnet and colleagues. Note, a series is used! The actual matrix that is used depends on how similar the sequences to be aligned at this alignment step are. Different matrices work differently at each evolutionary distance.

Alternatively, you can read in your own (just one matrix, not a series). Nucleotide multiple alignment matrix options This gives a menu where you are offered amenu where a single matrix (not a series) can be selected. Filename of user multiple alignment matrix Filename of user multiple alignment matrix Slow pairwise alignment: gap opening penalty The penalty for opening a gap in the pairwise alignments. Slow pairwise alignment: gap extension penalty The penalty for extending a gap by 1 residue in the pairwise alignments. Fast pairwise alignment: similarity scores: K-Tuple size This is the size of exactly matching fragment that is used. INCREASE for speed (max= 2 for proteins; 4 for DNA), DECREASE for sensitivity. For longer sequences (e.g. >1000 residues) you may need to increase the default. Fast pairwise alignment: similarity scores: gap penalty This is a penalty for each gap in the fast alignments. It has little affect on the speed or sensitivity except for extreme values. Fast pairwise alignment: similarity scores: number of diagonals to be considered The number of k-tuple matches on each diagonal (in an imaginary dot-matrix plot) is calculated. Only the best ones (with most matches) are used in the alignment. This parameter specifies how many. Decrease for speed; increase for sensitivity. Fast pairwise alignment: similarity scores: diagonal window size This is the number of diagonals around each of the 'best' diagonals that will be used. Decrease for speed; increase for sensitivity. Fast pairwise alignment: similarity scores: suppresses percentage score Fast pairwise alignment: similarity scores: suppresses percentage score Multiple alignment: Gap opening penalty The penalty for opening a gap in the alignment. Increasing the gap opening penalty will make gaps less frequent. Multiple alignment: Gap extension penalty The penalty for extending a gap by 1 residue. Increasing the gap extension penalty will make gaps shorter. Terminal gaps are not penalised. Use end gap separation penalty End gap separation: treats end gaps just like internal gaps for the purposes of avoiding gaps that are too close (set by 'gap separation distance'). If you turn this off, end gaps will be ignored for this purpose. This is useful when you wish to align fragments where the end gaps are not biologically meaningful. Gap separation distance Gap separation distance: tries to decrease the chances of gaps being too close to each other. Gaps that are less than this distance apart are penalised more than other gaps. This does not prevent close gaps; it makes them less frequent, promoting a block-like appearance of the alignment. No residue specific gaps Residue specific penalties: amino acid specific gap penalties that reduce or increase the gap opening penalties at each position in the alignment or sequence. As an example, positions that are rich in glycine are more likely to have an adjacent gap than positions that are rich in valine. List of hydrophilic residues This is a set of the residues 'considered' to be hydrophilic. It is used when introducing Hydrophilic gap penalties. No hydrophilic gaps Hydrophilic gap penalties: used to increase the chances of a gap within a run (5 or more residues) of hydrophilic amino acids; these are likely to be loop or random coil regions where gaps are more common. The residues that are 'considered' to be hydrophilic are set by '-hgapres'. Cut-off to delay the alignment of the most divergent sequences This switch, delays the alignment of the most distantly related sequences until after the most closely related sequences have been aligned. The setting shows the percent identity level required to delay the addition of a sequence; sequences that are less identical than this level to any other sequences will be aligned later.
