**This tool will attempt to reuse the metadata from your first input.** To change metadata assignments click on the "edit attributes" link of the history item generated by this tool.

.. class:: infomark

**TIP:** If your data is not TAB delimited, use *Text Manipulation-&gt;Convert*

-----

This tool goes line by line through the specified input file and
if the text in the selected column matches a specified regular expression pattern
replaces the text with the corresponding specified replacement.

This tool can be used to change between the chromosome naming conventions of UCSC and Ensembl.  

For example to remove the **chr** part of the reference sequence name in the first column of this GFF file::

Setting::

 using column: c1 
 Find Regex: chr([0-9]+|X|Y|M[Tt]?) 
 Replacement: \1 

produces::

This tool uses Python regular expressions with the **re.sub()** function. 
More information about Python regular expressions can be found here:
http://docs.python.org/library/re.html.

The regex **chr([0-9]+|X|Y|M)** means start with text **chr** followed by either: one or more digits, or the letter X, or the letter Y, or the letter M (optionally followed by a single letter T or t).  
Note that the parentheses **()** capture patterns in the text that can be used in the replacement text by using a backslash-number reference:  **\\1**


In the replacement pattern, use the special token #{input_name} to insert the input dataset's display name.
The name can be modified by a second find/replace check. Suppose you want to insert the sample id of your dataset,
named **Sample ABC123**, into the dataset itself, which currently contains the lines::
Data 1
Data 2
Data 3

You can use the following checks::
Find Regex: Data
Replacement: #{input_name} Data

Find Regex: Sample (\S+)
Replacement: \1

The result will be::
ABC123 Data 1
ABC123 Data 2
ABC123 Data 3
