Create sublists according to numerical values

This software analyses tables in CSV (separator TAB) with 2 columns : items and values. Sublists above threshold AND/OR below (1/threshold) are then created.

Example of application : obtain lists of variable sizes of deregulated genes/proteins according to their fold change.

Manual :

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

2- unzip the software

3- copy data csv (TAB delimitated only) files in the “data” directory.

tables must have 2 columns with a name in the first column and a numerical value in the second column :

name {tabulation} value

name {tabulation} value

name {tabulation} value

....

4- execute the software by the command : perl software_name or double click on the .pl file. You can select among 3 softwares : ALL, UP and DOWN.

5- processed files are in the “results” directory.

The files.log file gives you some information about the thresholds and the number of lines of each file.

You can optionnally edit the default parameters values in the parameters.txt configuration file :

#####################

# configuration file

#####################

# number of lists you want to obtain

lists_number = 10

# lists values are above the value_threshold and below 1/value_threshold

value_threshold = 1.5

# step of value threshold between two sublists

step = 0.25
