AgilentMicroarray (.txt)

Background & Context

Import

  • 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 following reference pages for full general information:
  • Importimport from a file
    CloudImportimport from a cloud object
    ImportStringimport from a string
    ImportByteArrayimport from a byte array

Import 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.
