 +====== Affymetrix raw data files: CEL files ======
  
 +**.[[CEL]]** is the extension used by [[Affymetrix]] to name data files storing probe intensity measurements. Information about the array design characteristics such as location of probes, probe-sets and probe-pairs is stored by Affymetrix in [[CDF]] files.
 +
 +In an experiment carried out using [[Affymetrix]] technology you will have a [[CEL]] file for each of the arrays you hybridized.
 +
 +In [[Babelomics]], [[CEL]] files are considered to be the [[raw data]] files of the [[Affymetrix]] platform.
 +
 +Some [[CEL]] files can be in text format but most of them wil be in ASCII or binary format.  Do not be too surprised if you cannot open them using a text editor or an spreadsheet.
 +
