Hello everybody,
I've noticed that read.maimages doesn't read the same type of value
for the signal and the background. If I'm not wrong Imagene output
file has three values for them(mean,median and mode); apparently by
default read.maimages takes the mean for the signal and the median for
the background...
For example, how can I extract the median signal and the median
background?
I tried not to use the parameters source="imagene" and I've defined
the columns of desired values:
>RG<-read.maimages(files,R="Signal Mean",Rb="Background
Mean",G="Signal Mean",Gb="Background mean")
but I got this message:
Error in read.maimages(files, R = "Signal Mean", Rb = "Background
Mean", :
Cannot find column heading in image output file
please somebody help me out!
sorry if once again I bother You with my basic questions...
Thanks in advance.
Emanuele
