The search box can be displayed by pressing the keys Control and F or selecting - "Search"

-Note: - -

Using the "Create new group" is a quick way to group and highlight - residues with the specified search pattern throughout the alignment.

Search

+

The search box is displayed by pressing Control and F or + selecting "Find..." from the "Search" menu.

+ +

"Find next" will find the next occurence of the specified and adjust + the alignment window view to show it, and "Find all" highlights all + matches for a pattern. The "New Feature" is a quick way to highlight + and group residues matching the specified search pattern throughout the alignment. +

+

Creating Features from Search Results

+

+ If "New Feature" is selected, the feature can be given a name from + a popup input box. Use the "Feature Settings" under the "View" + menu to change the visibility and colour of the new sequence feature.

A quick Regular Expression Guide

+

A regular expression is not just a simple text query - although it +can be used like one, the query is not parsed literally, but +interpreted like a series of instructions defining the features of the +match. For example, a simple query like "ACDED" would +match all occurences of that string, but "ACD+ED" matches +both 'ACDDED' and 'ACDDDDDDDDED'. More usefully, the query +"[ILGVMA]{;5,}" would find stretches of small, +hydrophobic amino acids of at least five residues in length. +

+

The table +below describes some of the regular expression syntax:
