-"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:
| Regular Expression Element | -Effect | -
| . | -Matches any single character | -
| [] | -Matches any one of the characters in the brackets | -
| ^ | -Matches at the start of an ID or sequence | -
| $ | -Matches at the end of an ID or sequence | -
| * | -Matches if the preceding element matches zero or more times | -
| ? | -Matches if the preceding element matched once or not at all | -
| + | -Matches if the preceding element matched at least once | -
| {count} | -Matches if the preceding element matches a specified number of - times - | -
| {min,} | -Matches of the preceding element matched at least the - specified number of times | -
| {min,max} | -Matches if the preceding element matches min or at most max - number of times | -
