| readImaGeneHeader {limma} | R Documentation |
Read the header information from an ImaGene image analysis output file.
This function is used internally by read.maimages and is not usually called directly by users.
readImaGeneHeader(file)
file |
character string giving file name or path |
The raw data files exported by the image analysis software ImaGene include a number of header lines which contain information about the printing and scanning processes. This function extracts that information and locates the line where the intensity data begins.
A list containing information read from the header of the ImaGene file.
Each Begin-End environment found in the file header will become a recursive list in the output object, with components corresponding to fields in the file.
See the ImaGene documentation for further information.
The output object will also contain a component NHeaderRecordsgiving the number of lines in the file before the intensity data begins.
