ES_SIMULATE_PERTURBATION - Predict the effects of a given differential profile
r = es_simulate_perturbation(N,W,ind_ext,u_ratio,s_ratio,es_result,expansion,expansion_order)
Compute the predicted effects of a given differential profile
of enzyme expression (u) and external metabolites (s)
on balanced concentrations c and fluxes j
based on an expansion using the response coefficients in "es_result"
N, W, ind_ext: structural information about the network
s_ratio: external concentration ratio vector
u_ratio: expression ratio vector
es_result: output from a previous elasticity sampling (function 'sample_model')
expansion: {'logarithmic','non-logarithmic'}
-> depending on the expansion type, the output refers to logarithmic
or non-logarithmic values;
expansion_order 1 or 2 expansion_order of the expansion
output r contains the ratios etc.
