Hello
I have microarray data in tab delimited text file.The main headers and some
fields are as:
following are the header:

FEATURES FeatureNum Row Col SubTypeMask ControlType ProbeName
SystematicName PositionX PositionY LogRatio LogRatioError
PValueLogRatio gProcessedSignal rProcessedSignal gProcessedSigError
rProcessedSigError gMedianSignal rMedianSignal gBGMedianSignal
rBGMedianSignal gBGPixSDev rBGPixSDev gIsSaturated rIsSaturated
gIsFeatNonUnifOL rIsFeatNonUnifOL gIsBGNonUnifOL rIsBGNonUnifOL
gIsFeatPopnOL rIsFeatPopnOL gIsBGPopnOL rIsBGPopnOL IsManualFlag
gBGSubSignal rBGSubSignal gIsPosAndSignif rIsPosAndSignif
gIsWellAboveBG rIsWellAboveBG SpotExtentX gBGMeanSignal rBGMeanSignal



following is the data corresponding to the above header :
