Authority: ssg.uab.edu - Name: getGeneExpressionDataForNASCExperimentID Desc: Retrieve gene_expression data for a supplied in NASC Expreriment Id Database Info: Connects to a gene_expression database with image processed microarray expression values for Affymetrix ATH1 arrays/slides provided by NASC. Input: Enter a valid NASC Experiment ID. Exp_Id is a positive integer number used to identify a single NASC Experiment. For valid experiments Ids, visit http://affymetrix.arabidopsis.info/AffyList.html . Other Inputs: Seconday Input: Specify a image processing algorithm of interest. Current version supports RMA, GCRMA & MAS5. Output Data: A collection of multi_slide_expression_values. A 'multi_slide_expression_values' datatype models a MxN matrix of gene_expression_values, where M(row) are Affy ATH1 probeset Ids and columns are NASC Slide names.
