AgilentMicroarray (.txt)

  • Import fully supports the Agilent microarray format.
  • Background

      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 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.

    Elements

    • 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 ("LabeledFeatureTable", "Header", "Statistics").
    • Import uses the "FeatureTable" element by default.
