Hi. I am an undergraduate working in a biology lab that studies arabidopsis guard cells. My mentor has assigned me with a project to write code that will take gene expression data from an affymetrix microarray chip and then interpret that into a meaningful graphical representation of gene expression values for the cells. My question is regarding the actual form of the data. I realize that microarrays return data in the form of what looks like colored grids of green and red. However, I am confused regarding the nature of "gene expression values". How is an expression value quantified? Understanding the nature of the data would assist greatly with my work as I am concerned with understanding what I am doing more so than blindly installing R's Bioconductor package and surviving off of web tutorials. Thank you for any help in explaining this process.
