AMEN 1.5.0 is out!!!

Dear User,
IMPORTANT: The AMEN installer for windows is no more available. See the installation procedure in the README.txt file for more details on how to download, install and run AMEN. Moreover, the GraphViz program was replaced by the "igraph" R library" to draw network into AMEN.

Several changes including probably the most important one since the AMEN creation: Annotation and Network data files are now automatically generated! There's no more need to download different databases and convert them! Just use the "Menu>Options>Download databases" module.
Other changes:
- "Main entries" are now called "Reference entries".
- Annotation and interaction data files could now include "multi-reference entries" (separated by semi-colon ';') as "reference entries" (1rst column)
- "Upload data" was removed and associated modules were moved into either "Expression" or "Options" menu... read more

AMEN v.1.2.1 is out!

Dear User,
IMPORTANT: User must install the 8.6beta version of Tcl/Tk (ActiveTcl) which already include the tkImg package. So user will not need to install this package.
One major change:
- During the installation process, the "TMP" folder is not required anymore. AMEN automatically creates this folder into its installation directory. Moreover AMEN automatically installs the required R packages into the "AMEN/RLIBRARIES" folder. This change should facilitate the installation for users which do not have administrator privileges. On the other hand, the user must be the owner of the installation folder ("AMEN" by default).
Apparently, there's still a problem to install automatically R packages on MAC OS. This beug should be fixed on the next version.... read more

AMEN v.1.1.0 released: 3 major and one minor bugs fixed !

Dear All,
In the current version of AMEN, three major and one minor bugs were fixed
Three major bugs:
- the "CLARA" clustering module did not work anymore. It was just a typo mistake on a procedure name.
- the Heatmap and the Mapping modules did not work. I used "global" with a cell of a array instead of with the corresponding array.

One minor bug:
- In the new Tcl/Tk version (8.5.0) there is a bug using the "pow" option of the expr procedure. puts [expr pow(10,-1)] returns 0.10000000000001 instead of 0.1. I correct this error.... read more
