Hello,
Is there a way to calculate the Boltzmann weighted average of thermodynamic properties calculated using the hsa_gist command of the SSTMap tool?
thank you
The Boltzmann Weighted average for a thermodynamic property X is given by the following equation:
= ∑X_i e^(-E_i/kT) / ∑e^(-E_i/kT)
where X_i is the value of the property for the i-th state, E_i is the energy of the i-th state, T is the temperature in Kelvin, k is the Boltzmann constant (1.38 x 10^-23 J/K), and the summation is over all states accessible to the system.
To calculate the Boltzmann Weighted average, you need to know the values of the property X and the energy E for each state. The Boltzmann factor, e^(-E_i/kT), describes the probability of the system being in the i-th state, based on the energy of the state and the temperature of the system. The Boltzmann factor assigns a weight to each state based on its energy and the temperature of the system, with lower energy states having a higher weight at lower temperatures.
To perform the calculation, you need to sum the product of X_i and e^(-E_i/kT) over all states, and then divide by the sum of e^(-E_i/kT) over all states. This gives you the Boltzmann Weighted average of the property X for the system.
Note that this calculation assumes that the system is in thermal equilibrium, meaning that the temperature is constant and the system has reached a state where the probabilities of each accessible state are fixed.
