**What it does**

This tool finds $ replaces text in an input dataset.

.. class:: infomark

The **pattern to find** can be a simple text string, or a perl **regular expression** string (depending on *pattern is a regex* check-box).

.. class:: infomark

When using regular expressions, the **replace pattern** can contain back-references ( e.g. \\1 )

.. class:: infomark

This tool uses `Perl regular expression <https://perldoc.perl.org/perlre>`_ syntax.

-----

**Examples of *regular-expression* Find Patterns**

- **HELLO**     The word 'HELLO' (case sensitive).
- **AG.T**      The letters A,G followed by any single character, followed by the letter T.
- **A{4,}**     Four or more consecutive A's.
- **chr2[012]\\t**       The words 'chr20' or 'chr21' or 'chr22' followed by a tab character.
- **hsa-mir-([^ ]+)**        The text 'hsa-mir-' followed by one-or-more non-space characters. When using parenthesis, the matched content of the parenthesis can be accessed with **\1** in the **replace** pattern.


**Examples of Replace Patterns**

- **WORLD**  The word 'WORLD' will be placed whereever the find pattern was found.
- **FOO-$&-BAR**  Each time the find pattern is found, it will be surrounded with 'FOO-' at the begining and '-BAR' at the end. **$&** (dollar-ampersand) represents the matched find pattern.
- **$1**   The text which matched the first parenthesis in the Find Pattern.


-----

**Example 1**

**Find Pattern:** HELLO
**Replace Pattern:** WORLD
**Regular Expression:** no
**Replace what:** entire line

Every time the word HELLO is found, it will be replaced with the word WORLD.

-----

**Example 2**

**Find Pattern:** ^chr
**Replace Pattern:** (empty)
**Regular Expression:** yes
**Replace what:** column 11

If column 11 (of every line) begins with ther letters 'chr', they will be removed. Effectively, it'll turn "chr4" into "4" and "chrXHet" into "XHet"


-----

**Perl's Regular Expression Syntax**

The Find & Replace tool searches the data for lines containing or not containing a match to the given pattern. A Regular Expression is a pattern descibing a certain amount of text.

- **( ) { } [ ] . * ? + \\ ^ $** are all special characters. **\\** can be used to "escape" a special character, allowing that special character to be searched for.
- **^** matches the beginning of a string(but not an internal line).
- **(** .. **)** groups a particular pattern.
- **{** n or n, or n,m **}** specifies an expected number of repetitions of the preceding pattern.

  - **{n}** The preceding item is matched exactly n times.
  - **{n,}** The preceding item ismatched n or more times.
  - **{n,m}** The preceding item is matched at least n times but not more than m times.

- **[** ... **]** creates a character class. Within the brackets, single characters can be placed. A dash (-) may be used to indicate a range such as **a-z**.
- **.** Matches any single character except a newline.
- ***** The preceding item will be matched zero or more times.
- **?** The preceding item is optional and matched at most once.
- **+** The preceding item will be matched one or more times.
- **^** has two meaning:
  - matches the beginning of a line or string.
  - indicates negation in a character class. For example, [^...] matches every character except the ones inside brackets.
- **$** matches the end of a line or string.
- **\\|** Separates alternate possibilities.
- **\\d** matches a single digit
- **\\w** matches a single letter or digit or an underscore.
- **\\s** matches a single white-space (space or tabs).
