In this module you can select a series of parameters that can be saved in a comma-separated file (extension .csv) at the end of the hydrodynamic computations. The module consists of eight, tab-selectable screens where the parameters are subdivided according to their origin and characteristics. The parameters can be toggled from one window of the panel to the other (left side, list of parameters available; right side, parameters to be saved) by clicking on them (multiple selection available; you can scroll down while keeping pressed the central mouse button to select a contiguos series of parameters) and then using the arrows present between the two windows.
The eight screens are Main hydro results:, Additional SMI results:, Additional ZENO results:, Additional GRPY results:, Additional vdW results:, Solvent conditions:, ASA results and options:, and Fractal Dimension:. Note that the order by which you select the parameters (i.e. the order by which they appear in the right-side window) will be their order in the saved file. The Model name "parameter" is the only one which is fixed, alwas available and not selectable, because it will be used to distinguish the results of individual models when multiple models (such as from NMR-style files) are analyzed in a single run.
The Main hydro results: screen contains all parameters which are listed in the Show Hydrodynamic Calculations pop-up window, plus some other general parameters i.e.:
Total beads in model
Used beads in model

Used bead mass [Da]
Total surface area of beads in the model [nm^2]
Total volume of beads in the model [nm^3]
Number of unused beads (this differs from what is reported in the *.hydro_res file because the used beads are already listed in the Main hydro results panel)

The Additional SMI results: screen contains all the other parameters which are reported in the *.hydro_res file:

The Solvent conditions: screen contains the parameters as set in the
Hydrodynamic Calculations options module:

pH
The ASA results and options: screen contains first two parameters, derived from the ASAB1 execution, and then the settings used for the vdW with overlaps method to perform the atomic hydration and to identify the buried beads for their exclusion in the GRPY computations:
Radius of gyration (+r) [A] (from PDB atomic structure) (computed by taking into account the actual radius r of each atom)
Radius of gyration (-r) [A] (from PDB atomic structure) (computed without taking into account the actual radius r of each atom)
ASA Hydrate probe radius [A]
