dataset	an R data frame generated with generateDatasetFile
funName	the function used to summarize the two channels, for example divideChannels
colname4ch1	a character string specifying the name of the dataset column containing the first channel
colname4ch2	a character string specifying the name of the dataset column containing the second channel

Details

The original dataset columns are saved as extra columns with the suffix ".old" by the function saveOldIntensityColumns.

Value

A list containing:

header	the header with an entry about the channel summarization added in the comments section
newDataset	the new dataset
