[…] All the data measured by TelQuant analysis was analysed using Excel. Clusters were made using CLUSTER3 () (∼mdehoon/software/cluster/) and viewed by the JAVA TREEVIEW program ( (). Preliminary analysis of mutants affecting known protein complexes showed that this method gave the best results. The 30 mutants analysed here were chosen based on the following criteria: (i) short mutants were analysed; (ii) one representative of each known complexes was chosen (with the exception of the mutants used for calibrating TELKA, which belonged to known complexes); (iii) their final telomere length was at least 10% shorter than the wt length. Comparing the intra-cluster Euclidian distances in the clusters obtained to a set of a million random permutations of the dataset resulted in an empirical P-value <10−6. […]
