Preprocessing tools


Preprocess DNA array data files
Log-transformation, replicate handling, missing value imputation, filtering and normalization. The resulting dataset can be sent to our local DNA array analysis tools and to the EPclust (@EBI).
Knowledge Filtering
This tool queries a database with the list of gene identifiers of the expression pattern data file and allows to select patterns based on their clasification in the database.
IDconverter
Map your ids to other known public DBs (HUGO, Ensembl Gene, GenBank, Swiss-Prot, etc).
