eXpress is a streaming DNA/RNA sequence quantification tool. It has initially 
been tested for RNA-Seq transcriptome quantification but can be used in any 
application where abundances of target sequences need to be estimated from short 
reads sequenced from them.

More details, installation instructions, and the manual can be found at 
http://bio.math.berkeley.edu/eXpress/

--------------------------------------------------------------------------------
I.   Authors:
--------------------------------------------------------------------------------

The methods and algorithms used in eXpress were developed by Adam Roberts and 
Lior Pachter. Adam Roberts designed and wrote eXpress. 

--------------------------------------------------------------------------------
II.  Requirements:
--------------------------------------------------------------------------------

eXpress is a standalone tool that requires gcc 4.0 or greater, and runs on Linux 
Macintosh OS X, and Windows.  

It depends on Boost (http://www.boost.org), 
BamTools (https://github.com/pezmaster31/bamtools),
ZLIB (http://zlib.net/),
and the Microsoft Visual C++ Runtime Library (Windows only) 
(http://www.microsoft.com/download/en/details.aspx?id=5555).
