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

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:
