- | 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.
