schrodinger.application.livedesign.data_classes2 module

class schrodinger.application.livedesign.data_classes2.LDData(data_name=None, family_name=None, user_name=None, requires_3d=False, requires_ffc=False)

Bases: object

Class for storing information about Maestro-level data that may be exported to LiveDesign. (Objects from this class should only store Maestro-level data, not LiveDesign data.)

Specifically, this class is not meant to store the values of the data to be exported, but rather to serve as a “view” to that data. It should

  1. provide identifying information to the user about the data that is
    available for export (e.g. by providing user-friendly property names to tables and other view widgets), and
  2. provide an internal “pointer” to data to be exported (by uniquely
    identifying exactly what data should be exported, as selected by the user)

This class is meant to be general enough to store information about both structure property data and attachment data (e.g. 3D, images, files).

__init__(data_name=None, family_name=None, user_name=None, requires_3d=False, requires_ffc=False)

Instances representing structure properties should be initialized with the property data name (e.g. data_name="s_m_title").

If there is no data name, e.g. for image and attachment data, instances should be initialized with both the family name and the user name (e.g. “Atom Properties”, “Hot Atoms”).

If the family or user name is supplied along with the data name, these will be used for display purposes within the panel rather than the values derived from the data name.

Raises:ValueError – if insufficient information is supplied on initialization to fully specify a unique instance
family_name

Return the family name if provided on initialization. Otherwise, determine family name from the data name.

Returns:family name for display
Return type:str
user_name

Return the user name if provided on initialization. Otherwise, determine user name from the data name.

Returns:user name for display
Return type:str
data_name

Return data name if provided on initialization.

Returns:data name or None
Return type:str or None
requires_3d
Returns:whether the export of this data requires the export of 3D data
Return type:bool
requires_ffc
Returns:whether this data needs to be export as a freeform column
Return type:bool
class schrodinger.application.livedesign.data_classes2.ReceptorLigandPair(receptor=None, ligand=None)

Bases: object

Data class for storing a receptor structure and a ligand structure.

__init__(receptor=None, ligand=None)

Initialize self. See help(type(self)) for accurate signature.

class schrodinger.application.livedesign.data_classes2.ReceptorLigandGroup(receptor=None, ligand=None, alt_ligand=None, add_rl_pairs=None)

Bases: object

Data class for unambiguously storing a group of receptor and ligand structures. In addition to the primary ligand, this class also supports storing an “alternate” ligand meant for 3D upload in place of the primary ligand and “additional” ligands meant for 3D upload in addition to the primary ligand.

The alternate ligand may have a distinct ligand pose, or it may have a different structure entirely. For example, the primary ligand may be a ligand after covalently binding to a receptor, and the alternate ligand may be the independent ligand molecule prior to complexing.

Each of these structures is optional; a ReceptorLigandGroup instance will not always need to contain a receptor and a ligand, or any other structures.

__init__(receptor=None, ligand=None, alt_ligand=None, add_rl_pairs=None)
Parameters:
  • receptor (structure.Structure or None) – a receptor structure or None
  • ligand (structure.Structure or None) – a ligand structure or None
  • alt_ligand (structure.Structure or None) – extra structure data associated with the ligand, e.g. to be used as 3D data for certain LiveDesign uploads
  • add_rl_pairs (list(ReceptorLigandPair) or None) – additional ligand/receptor structures to be uploaded as 3D data in addition to the conventional (ligand or alternate ligand) 3D uploads
class schrodinger.application.livedesign.data_classes2.ReceptorLigandMap

Bases: collections.defaultdict

A specialized dictionary for organizing receptor and ligand structures. Each key points to a list of receptor-ligand groups associated with that key. For convenience, this class also features several generators.

__init__()

Initialize as a list-based collections.defaultDict.

num_rl_groups
Returns:the number of receptor-ligand groups stored in this object.
Return type:int
rl_group_items
Returns:an iterator for (key, receptor-ligand group) pairs stored in this map. Note that each key can correspond to multiple receptor- ligand groups.
Return type:iterator((str, ReceptorLigandGroup))
rl_groups
Returns:an iterator for receptor-ligand group objects stored in this map.
Return type:iterator(ReceptorLigandGroup)
ligand_items
Returns:an iterator for (key, ligand) pairs stored in this map
Return type:iterator((str, structure.Structure))
ligands
Returns:an iterator for ligand structures stored in this map
Return type:iterator(structure.Structure)
alt_ligand_items
Returns:an iterator for (key, alternative ligand) pairs stored in this map
Return type:iterator((str, structure.Structure))
alt_ligands
Returns:an iterator for alternative ligand structures stored in this map
Return type:iterator(structure.Structure)
add_rl_pair_items
Returns:an iterator for (key, additional receptor-ligand pair) 2-tuples stored in this map
Return type:iterator((str, ReceptorLigandPair))
add_rl_pairs
Returns:an iterator for additional receptor-ligand pairs stored on this map
Return type:iterator(ReceptorLigandPair)
receptor_items
Returns:an iterator for (key, receptor) pairs stored in this map
Return type:iterator((str, structure.Structure))
receptors
Returns:an iterator for receptor structures stored in this map
Return type:iterator(structure.Structure)
structures
Returns:an iterator for all structures stored in this map
Return type:iterator(structure.Structure)
__contains__()

True if D has a key k, else False.

__len__

Return len(self).

clear() → None. Remove all items from D.
copy() → a shallow copy of D.
default_factory

Factory for default value called by __missing__().

fromkeys()

Returns a new dict with keys from iterable and values equal to value.

get(k[, d]) → D[k] if k in D, else d. d defaults to None.
items() → a set-like object providing a view on D's items
keys() → a set-like object providing a view on D's keys
pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised

popitem() → (k, v), remove and return some (key, value) pair as a

2-tuple; but raise KeyError if D is empty.

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D
update([E, ]**F) → None. Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values
schrodinger.application.livedesign.data_classes2.get_long_family_name(short_family_name)

Given the short family name of a structure property (e.g. “m”), return the corresponding long family name (e.g. “Maestro”). If no long family name is defined, return the short family name argument.

Parameters:
  • short_family_name – the short family name of a structure property
  • short_family_name – str
Returns:

the corresponding long family name if one exists, otherwise the short family name

Return type:

str
