Input Data

To load a set of CEL files as raw data they should be compressed in a .zip archive with a name without spaces. It is also possible to load already normalized data in a text file, in which the first column should be the probeset IDs and subsequent columns contain the normalized data for each sample. The first line is a header with the sample names (also used in the setup-file). Avoid using sample names starting with numbers. See the example files under General instructions.

Input Setup

The setup file should describe the experimental setup assigning each sample to a specific condition. The format of the file should be as follows: The first column should contain the names of the CEL files (or the sample names used in the header of the normalized data file) and additional columns should assign attributes in some category to each array. See the example files under General instructions.

Microarray Quality Check

Raw or pre-normalized microarray data are subjected to the classical preprocesing steps (normalization, probe set summarization). A number of quality controls are then run on the preprocessed data in order to identified potential erronous arrays that may be removed before subsequent downstream analysis.
