Network analysis was performed with the R package igraph by considering only pairs of metabolites with a Pearson correlation coefficient above 0.6. Outliers were not removed. Ten mice were used for each group, except for AL at 22°C (nine mice). All 90 plasma metabolites and 37 hypothalamic metabolites were used to compute the correlations [all metabolites found except those hypothalamic metabolites that were measured at 22°C but could not be found at 30°C: PC(32:0), SM(d18:1/17:0), erythro-sphingosine, arachidonoylglycerol, NADP+, and homoarginine]. The number of samples used to calculate the correlation between any two metabolites was the same (39 samples at 22°C and 40 samples at 30°C).




Best regards,


Carlos
