Thank you for your explanation.

I think I should take a step back and start from the top.

I want to calculate the vapor pressure of certain molecules using MC.

1. Is GEMC the most effective way to meet my objective? If not, what is a better way to obtain vapor pressure using RASPA?

2. After further studying the Non-Basic/Gibbs_CO2 example output, I found that the pressure has not been calculated. I am assuming that if I can get the pressure for both vapor and liquid systems, this will be the saturation pressure at the given temperature and calculated system volumes for each system. Please let me know if I am misunderstanding something.

3. How do I get RASPA to compute pressure for GEMC?

4. If I am simulating a molecule, where the critical properties are not known, can I use RASPA to estimate the critical properties? (The previous studies do not show data points close to the critical point.)
