How to measure or assign hydrophobicity score values to individual amino acids of a PDB structure? I want measure the hydrophobicity of each amino acid within a PDB structure file.  Since I have the PDB file I want to consider the 3D information, rather than sequence-only measures such as GRAVY.

I am not interested in measuring the SASA (solvent accessible surface area) or RD (residue depth) - although correlated, it is not the information I require.

How can I comparatively measure the hydrophobicity of the amino acids within a PDB structure file?  Is there an algorithm, library or program to do so?
No, this doesn't makes sense (I think).

The hydrophobicity of an AA is the hydrophobicity of the AA, in whatever context, just like it's molecular weight. It's weight is it's weight, in a structure or in isolation.

I know this seems physically unrealistic, but so is an abstract measure of 'hydrophobicity', it's just the best we can do based on partition coefficients.
