-Before any meaningful analysis can be done using your genomic data, they will need to go under a thorough //​cleaning//​ process. Microarray [[microarray_normalization|data normalization]] is the paradigm of such data reshaping processes, but not the only one. Mathematical transformations of your data like taking logarithms, missing data considerations ​or gene ID conversion are among them. In general the purpose of this step is to shape your data into a distribution which will be suitable in further steps of the analysis. [[Babelomics]] **preprocessing tools** allow you doing such data transformations.+Before any meaningful analysis can be done using your genomic data, they will need to go under a thorough //​cleaning//​ process.
