Unsupervised hierarchical clustering analysis on methylation levels for the 5000 most deviating CpG sites in the EPIC methylation array. A value of 0.2 indicated low percentage of methylation and 0,8 a high percentage of methylation. Clustering of the DNA-methylation profiles for the IDH-mut astrocytomas in the retrospective cohort (N = 29) did not identify a T2-FLAIR mismatch-methylation associated phenotype
