Singular value vectors employed a The second control-related or treatment-related singular value vector, \(x_{\ell _{1}=2,j_{1}}\). Control: j 1=1, and treatment (stress): j 1=2. b The fourth tissue singular value vector, \(x_{\ell _{2}=4,j_{2}}\), AY: j 2=1, HC: j 2=2, heart: j 2=8, hemibrain: j 2=9, and spleen: j 2=10. Other tissue singular value vectors, ℓ 2≠4, can be found in Additional file 2
