Hi All,
I'm trying to work with One-color agilent data without much luck.
http://article.gmane.org/gmane.science.biology.informatics.conductor/128
18/match=agilent
I've tried the above method but as I posted before I get stuck on the
following error.
Error in readGenericHeader(fullname, columns = columns, sep = sep) :
Specified column headings not found in file
As such I thought I'd try a different approach and have a go with the
LimmaGUI.
I've faked green channel columns in my files like this which I hope to
ignore once imported.
FEATURES FeatureNum Block Row Col SubTypeMask
SubTypeName ProbeUID ControlType ProbeName GeneName
SystematicName PositionX PositionY gProcessedSignal
rProcessedSignal gMeanSignal rMeanSignal
gMedianSignal rMedianSignal gBGUsed rBGUsed
DATA 1 1 1 1 0 0 1
GE_BrightCorner GE_BrightCorner GE_BrightCorner 9790.72 223.949 358.8079
1.52E+04 1.10E+04 1.10E+04 10446 10446 78.8743
78.8743
When I try to import the files I gives an error saying it was unable to
read the image processing files
I've also added a Block column as the next error is in getLayout(gal)
GAL file must contain Block, Column, Row error.
Then Error in Matrix and other but I guess this is all due to the file
not being read properly in the first place.
I am using another analysis package as well so I am analysing my data
but there is so much more to R.
Any help getting going would be greatly appreciated.
Many Thanks
Elliott
