Venn diagram comparison of the aligned features obtained by XCMS analysis. The numbers down to circles are the total number of identified features in the groups. The same blank samples for all the groups has been considered in the analysis. A and B are the results related to cortical samples; C and D present the data of the trabecular samples. To make the Venn diagrams, we used the venny 2.1 web application (https://bioinfogp.cnb.csic.es/tools/venny/index.html)
