save_coordinates_for_import(ui, coordinates_path, path_sets, save_features=False, shift_by_origin=True, centered=True)
Save the batch analyzer state as a optimisation set for subtomogram extraction.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
coordinates_path
|
path - like
|
The path to save the star file containing the particles. |
required |
path_sets
|
sequence of PathInfo
|
The path sets to the tomograms and molecules. |
required |
save_features
|
bool
|
Whether to save the features of the molecules to the star file. |
False
|
shift_by_origin
|
bool
|
If True, the positions will be shifted by the origin of the tomogram. This option is required if you picked molecules in a trimmed tomogram. |
True
|
centered
|
bool
|
If True, the positions will be centered around the tomogram center, and columns "rlnCenteredCoordinateX/Y/ZAngst" will be used. If False, columns "rlnCoordinateX/Y/Z" will be used. |
True

save_molecules(ui, save_path, layers, save_features=False, tomo_name_override='', shift_by_origin=True)
Save the selected molecules to a RELION .star file.
If multiple layers are selected, the MoleculeGroupID
column will be added
to the star file to distinguish the layers. This method is RELION 5 compliant.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
save_path
|
path - like
|
The path to save the star file. |
required |
layers
|
sequence of MoleculesLayer
|
The layers to save. |
required |
save_features
|
bool
|
Whether to save the features of the molecules. |
True
|
tomo_name_override
|
str
|
If provided, this will override the tomogram name identifier (the rlnTomoName column) in the star file. |
""
|
shift_by_origin
|
bool
|
If True, the positions will be shifted by the origin of the tomogram. This option is required if you picked molecules in a trimmed tomogram. |
True
