This function loads a cDNA microarray dataset into a temporary
string specifying a file name containing the
parameters to load data. This file must contain all the information
necessary to load the data, which are the following:
You can see an example of this configuration file in RHOME/library/maiges/doc/gastro/load\_gastro.conf.
This function takes the file name with initial arguments and load the
dataset specified by this config file. It generate a
maigesPreRaw object. During the process the function
writes a file named load.out on your working folder, that is a log of
the process, that you can check and verify if all was done
correctly. Obviously, the parameters dataDir,
sampleFile, geneMap, sep, gridR,
gridC, printTipR, printTipC and headers
must be specified. All other parameters may be specified as NULL and,
if so, they are ignored. It is possible to specify any fields that you
want in the headers parameter, but it is strongly recommended that
you specify the fields of spot intensity and background for both
channels and the filed giving quality weights for all spots.
This function returns a
maigesPreRaw object containing the dataset loaded.
Once an object of class
maigesPreRaw was generated, you
may use the functions
addPaths to load informaation about gene groups and gene
