a) Input Luminex File
This includes a matrix of protein concentrations for all samples and analytes to be included in the PCA. Please have the file in the following format. Please you test_luminex.txt as a template for this file.
b) Input Phenotype File
This includes information about sample phenotype. The first column (column name: SampleName) has the sample ID, which should be in the same order as it appears in the Input Luminex File. The second column (column name: Phenotype) has information about the group it belongs to. Please use test_phenotype.txt as a template for this file.
N.B: The code generates a pdf file, which can be later opened in illustrator to eliminate less useful arrows and annotations.
