Thus, [[Babelomics]] should not need such layout information and indeed, [[GAL]] files **cannot** be used in [[Babelomics]].

 +Hence, if your [[GPR]] files do not contain the array layout information you will not be able to normalize them using [[Babelomics]] normalization tools.
  
 In an experiment carried out using [[GenePix]] technology you will have one [[GPR]] file for each of the arrays or slides you hybridized. If you are doing a **one-color** hybridization the [[GPR]] file will contain information just for //one channel// signal. If you are doing a **two-color** hybridization the [[GPR]] file will contain information for //two channel// signals. In an experiment carried out using [[GenePix]] technology you will have one [[GPR]] file for each of the arrays or slides you hybridized.
