+====== Experimental design file format ======
+Experimental design is Tab-separated values file. This file has two columns, the first one corresponds to the sample name and the second one corresponds to the phenotype.
+<code>
+sample1	Group_1
+sample2	Group_1
+sample3	Group_2
+</code>
+**Note**: In case of **paired data** the Experimental design file must be **ordered**.
+Here is an example of a file with 4 piared samples (sample1_Normal and sample1_Treated are the same sample before and after treatment):
+<code>
+sample1_Normal	Group_1
+sample2_Normal	Group_1
+sample1_Treated	Group_2
+sample2_Treated	Group_2
+</code>
+Here is an other file example see {{:brca_normal-basal_ed.txt|}}.
