Under steady state conditions it is straight-forward to estimate s and d. Otherwise, the total levels at some other time point are needed.
TransformSnapshot(ntr, total, t, t0 = NULL, f0 = NULL, full.return = FALSE)
a named vector for s and d
the new to total RNA ratio (measured)
the total level of RNA (measured)
the labeling duration
time before measurement at which f0 is total level (only necessary under non-steady-state conditions)
total level at t0 (only necessary under non-steady-state conditions)
also return the provided parameters
t0 must be given as the total time in between the measurement of f0 and the given ntr and total values!
