%% Paper argumentation for fPCA part (figure 2)
% 0. Cut signals in 2 parts dominated by a) Deterministic rise (t = [50 200]) b) Stochastic oscillations (t = [200 650])
% 1. Do fPCA for all ligands at all doses (no inhibitors) for t = [50 200]
%    --> PC2vs3 - IGF one axis - BTC other axis - EGF/HGF/HRG inbetween - EPR/FGF not responding
%    Plot first 4 harmonics --> argument for choosing PCs 2 and 3
% 2. Visualize this with ellipses instead of points for IGF and BTC

% The following points are moved to figure 3
% 3. Subtract mean + first 3 harmonics (plot) from data for t = [200 650]
%    --> Histograms for no dose + highest dose with threshold
%    cell-to-cell heterogeneity <-> time-courses to show oscillations
%    Ligands triggering subpopulation to oscillate; Others don't
% 4. Do same analysis for inhibitor data (EGF and HGF): MEKi induces oscillations; AKTi represses oscillations
%    (Counter-intuitive: EGF-MEKi population mean like IGF, oscillations however not suppressed as for IGF)
