schrodinger.project.utils module

schrodinger.project.utils.get_PT()

Safe getter for the project instance that swallows exceptions that occur if the project has been closed.

Using this function avoids unnecessary tracebacks that occur if the project is requested in the brief period after the project has been closed before a new one is created.

Returns

a project instance, if a project is available in Maestro

Return type

project.Project or NoneType

schrodinger.project.utils.set_entries_pinned(entry_ids, pin)

Pin or unpin entries from the workspace.

Parameters

  • entry_ids (list(str)) – a list of entry IDs

  • pin (bool) – whether to pin or unpin the specified entries to the workspace

schrodinger.project.utils.set_entry_pinned(entry_id, pin)

Pin or unpin an entry from the workspace.

Parameters

  • entry_id (str) – an entry ID

  • pin (bool) – whether to pin or unpin the specified entry to the workspace

schrodinger.project.utils.set_entries_included(entry_ids, include, override_pin=False)

For the specified entries, either include them in or exclude them from the workspace.

Parameters

  • entry_ids (list(str)) – a list of entry IDs

  • include (bool) – whether to include (True) or exclude (False)

  • override_pin (bool) – if False, ignore pinned entries. If True, exclude entries that are set to be excluded even if they are pinned. If pinned entries are set to be included, leave them as pinned (because they are also included as pinned entries)

schrodinger.project.utils.set_entry_included(entry_id, include, override_pin=False)

For the specified entry, either include it in or exclude it from the workspace.

Parameters

  • entry_id (str) – an entry ID

  • include (bool) – whether to include (True) or exclude (False)

  • override_pin (bool) – if False, ignore pinned entries. If True, exclude entries that are set to be excluded even if they are pinned. If pinned entries are set to be included, leave them as pinned (because they are also included as pinned entries)

schrodinger.project.utils.entry_is_pinned(entry_id)

Return whether the specified entry is pinned in the workspace.

Parameters

entry_id (str) – the entry ID of a row in the project

Returns

whether the entry is pinned in the workspace

Return type

bool

schrodinger.project.utils.entry_is_included(entry_id)

Return whether the specified entry is included in the workspace.

Parameters

entry_id (str) – the entry ID of a row in the project

Returns

whether the entry is included in the workspace

Return type

bool

schrodinger.project.utils.entry_is_selected(entry_id)

Return whether the specified entry is selected in the project.

Parameters

entry_id (str) – the entry ID of a row in the project

Returns

whether the entry is selected in the project

Return type

bool

schrodinger.project.utils.set_entry_locked(entry_id, lock)

Set the supplied project table entry to be “locked” or “unlocked.”

These operations are grouped because they are both performed when locking an entry in the visual interface.

Parameters

  • entry_id (str) – the entry ID of a row in the project

  • lock (bool) – whether to lock or unlock the specified entry

schrodinger.project.utils.entry_is_locked(entry_id)

Return whether the supplied project entry is read-only and not deletable.

These properties are both tested because both values are set when locking an entry in the visual interface.

Parameters

entry_id (str) – the entry ID of a row in the project

Returns

whether the entry is locked

Return type

bool

schrodinger.project.utils.remove_entries(entry_ids)
