Thank you much Paul.

I'll take a look for map-to-model-correlation function.

In the meantime, I wonder if simply the function (density-at-point) computed at the ligand coordinates on an omit map would be easier to compare the ligand fits to the density.

Regards,

Rene

Hello Rene,


I am analyzing and comparing more than forty structures solved in complex with different ligands. I would like to estimate for the ligands in each structure the fit to electron density via COOT scripting. However, (score-residue-range-fit-to-map) function did not seem to work on non-standard residues.

I see what you mean. I haven't used that function in many years.

How about using the correlation coefficient? e.g.:

(map-to-model-correlation 0 (list (list "A" 1357 "")) '() 0 1)

There are related functions.

In addition, can anyone help me understand the difference between (score-residue-range-fit-to-map), (density_score_residue) and the values reported in the density fit graph ?


Not yet :-) More later though.

Paul.
