Clustering of archived, fresh and fecal immunochemical tests (iFOBT) fecal samples. Heatmap of the log transformed OTU table for all samples produced by hierarchical clustering and Euclidean distance. Only OTUs with a log sum > 20 were illustrated. iFOBT samples are marked in green, archived fecal samples stored for 14 to 16 years at − 30 °C are marked in blue and fresh samples are marked in pink. All samples are from presumably healthy individuals
