AgilentMicroarray (.txt)

Agilent microarray data format.
File format used for the storage and exchange of microarray data and meta-information.
ASCII format.
Output format of Agilent Feature Extraction and Agilent Genomic Workbench (AGW) software.
Contains three sub-tables, storing the Feature Extraction parameters, microarray-level statistics, and feature-level data.
  • Import fully supports the Agilent microarray format.

Import and ExportImport and Export

  • Import["file","AgilentMicroarray"] imports data from any Agilent microarray file.
  • Import["file",{"AgilentMicroarray",elem}] imports the specified element.
  • Import["file",{"AgilentMicroarray",{elem1,elem2,}}] imports multiple elements.
  • Import["file",{"AgilentMicroarray",elem, subelem}] imports the specified subelement.
  • Import["file",{"AgilentMicroarray",elem,{subelem1,subelem2,}}] imports multiple subelements.
  • See the reference pages for full general information on Import.
  • ImportString supports the Agilent microarray file format.

ElementsElements

  • General Import elements:
  • "Elements"list of elements and options available in this file
    "Rules"full list of rules for each element and option
  • Common data representation element:
  • "FeatureTable"raw feature table
    "LabeledFeatureTable"feature table as a list of rules
  • Meta-information element:
  • "Header"Feature Extraction parameters given as a list of rules
  • Array-wide statistics element:
  • "Statistics"array-wide statistics given as a list of rules
  • Use Import["file",{"AgilentMicroarray",elem,"Elements"}] to list the subelements available in each of the three main tables (, , ).
  • Import uses the element by default.
