Data Preprocessing Menu Documentation

You can find in this menu all tools for data preprocessing, including microarray normalization, id conversion and gene annotation.

Edit

This form will allow you to modify uploaded data. You can, for instance, add new rows or columns to your numerical matrices.

Normalize

Microarray data normalization is a first necessary step before data can be properly analyzed. Its goal is to standardize the measurements from all microarrays in the experiment into a common scale so that measurements across samples can be compared among them.

Using Babelomics you can normalize the following microarray platforms and settings:

Affymetrix Expression

You can use this menu to normalize Affymetrix 3' Gene Expression Analysis Arrays and Whole-Transcript Expression Exon and Gene Arrays.
