Quantile normalization

This software performs a quantile normalization and a log2 transformation (optional) of an unlimited number of data tables. Computation are based on the package preprocessCore. Files are processed in parallel for high throughput.

Manual :

1- if not already installed, install Perl free programming language

2- install R programming language and preprocessCore.

3- install GNU parallel (GNU Linux only)

4- unzip the software

5- copy data tsv files (TAB separator) in the “data” directory :

- first line : columns names

- first column : row names

next columns are the values, with separator TAB.

6- to enable log2 transformation edit the conf.txt file and set log2=1. Set your number of CPU using "nb_cpu="

7- execute the software by the command : perl parallel_Qnorm-0.1.pl

8- results are in the "results" directory
