Generates a Glide Grid from receptors or complexes. The node takes in 3 basic arguments, two of them (Center and Size) that can be specified either manually or by a Ligand. If a Ligand is needed in either of these arguments (Choose "Center of ligand" under Center, or "Ligand" under Size), then the Ligand needs to be specified (using the "Specify Ligand by" ComboBox). The third argument HBond Constraints can be specified by a string.

Backend implementation

utilities/generate_glide_grids
generate_glide_grids under utilities is used to implement this node.

Options

Save Grid

Whether the workflow saves the grid data (otherwise it saves a pointer to the files that exist on the file system)

Include Log in Output

The log is included in the output as a column

Include Out in Output

The out file is included in the output as a column

Center of ligand

The center of the ligand is used as the Center of the grid generation

Supplied X,Y,Z coordinates

Specify X,Y, and Z as the Center of the grid generation

Size Ligand

The size of the ligand is used as the Size of the grid generation

Size supplied values

Supply the Inner and Outer Box values to be used in the grid generation

Specify Ligand by

Options are Default ASL, Specified ASL, or the ASL in a column

HBond Constraints

Input a string of colon-separated H-bond constraints, specifying a user-defined label, which must be unique, followed by '#' and the atom number for any metal atom, polar H, N, or O atom in the receptor. Glide will automatically include symmetry-equivalent atoms. Example:'label1#atomnum1:label2#atomnum2:label3#atomnum3'

Parameter flow variables

Any valid option for this node can be specified through flow variables. Only String variables are accepted.
Usage:
Flow variable prefix keyword: GridGen
Note: To specify an option as flow variable, the flow variable name should be like:
keyword-option_name for single-dash option
keyword--option_name for double-dash option

To add a new option with value, specify the option_name and the corresponding value through flow variable.

To add a new option without value, specify the option_name and the value as _on_ through flow variable.

To override an existing option's value in the command line, just specify the option_name and the new value through the flow variable.

To remove an existing option from command line, just specify the option_name and the value as _off_ through the flow variable.
