SequenceLogo is a tool for drawing sequence logos of motifs. It gets Positional Count Matrices(PCMs) or IUPAC sequences as input and generates png-logos for a motif. Also one can create logo for reverse complement or even generate logos for a whole collection of motifs. Sequence logos are a graphical representation of an amino acid or nucleic acid multiple sequence alignment developed by Tom Schneider and Mike Stephens. Each logo consists of stacks of symbols, one stack for each position in the sequence. The overall height of the stack indicates the sequence conservation at that position, while the height of symbols within the stack indicates the relative frequency of each amino or nucleic acid at that position. In general, a sequence logo provides a richer and more precise description of, for example, a binding site, than would a consensus sequence (see http://weblogo.berkeley.edu/)

= Livedate A simple Rack middleware that parses a dates using Chronic, and returns the result in a standardized manner. The idea is to use this to verify the input in date input fields using AJAX, to provide immediate feedback to the user. == Usage Include Livedate in your middleware stack. In Rails, this is done in environment.rb config.gem 'livedate' config.middleware.use "Livedate" Specify the desired date + datetime formats you want too. Default error message for strings that Chronic can't pass can also be provided. The defaults are: config.middleware.use "Livedate", :date_format => '%Y-%m-%d', :datetime_format => ''%Y-%m-%d %H:%M', :invalid_format => '' This will catch requests to /parsedate. Use GET requests and provide a parameter 'date' or 'datetime'. The value will be parsed by Chronic and returned formatted as 2009-01-01 or 2009-01-01 12:45, depending on the parameter name. == Scripts There are two generators available to get simple javascripts that use livedate. Both will replace the contents on input elements with classes .date or .datetime on change with the result from the Chronic parse. script/generate livedate_jquery script/generate livedate_prototype Will put the appropriate version of the script in your public/javascripts directory. Feel free to change these if you need a different behavior.
= input_chronic A simple Rack middleware that parses a dates using Chronic, and returns the result in a standardized manner. The idea is to use this to verify the input in date input fields using AJAX, to provide immediate feedback to the user. == Usage Include "input_chronic" in your middleware stack. In Rails, this is done in environment.rb config.gem 'bjornblomqvist-input_chronic', :lib => 'input_chronic', :source => 'http://gems.github.com' config.middleware.use "input_chronic" This will catch requests to /gems.github.com/bjornblomqvist/input_chronic. Use GET requests and provide a parameter 'date' or 'datetime'. The value will be parsed by Chronic and returned formatted as 2009-01-01 or 2009-01-01 12:45, depending on the parameter name. Don't forget to add the javascript found at /javascript/input_chronic.js This is also implemented by catching the request before it reaches rails. To use this on a text input add the class chronic_date or chronic_datetime <input type="text" class="chronic_datetime" /> == Copyright Copyright (c) 2009 Erik Hansson, Bjorn Blomqvist.
