Hi David Have you looked into the excellent "Galaxy Unix-Tools" package created by Gordon Assaf? http://hannonlab.cshl.edu/galaxy_unix_tools/index.html The "Find & Replace text in line/column" tool is probably what you are looking for: http://hannonlab.cshl.edu/galaxy_unix_tools/galaxy.html#find_and_replace regards, Hans On 04/25/2011 11:20 PM, Jennifer Jackson wrote:

Hello David,

There are tools to select data based on defined attributes or to perform calculations on existing data (Text Manipulation, Filter and Sort), but as such no direct user-defined substitution tools.

Very sorry for any inconvenience,

Best,

Jen Galaxy team

Is there a tool for doing a global or column-based substitution in a text or tabular file? For example, replace all instances of the number 2 in a column to a number 1?
