cylindra_builtins.relion
This built-in plugin submodule provides functions to work with RELION file formats.
load_molecules(ui, path)
Read monomer coordinates and angles from RELION .star file.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
path
|
path - like
|
The path to the star file. |

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
|

save_splines(ui, save_path, interval=10.0, tomo_name_override='', shift_by_origin=True)
Save the current splines to a RELION .star file.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
save_path
|
path - like
|
The path to save the star file. |
required |
interval
|
float
|
Sampling interval along the splines. For example, if interval=10.0 and the length of a spline is 100.0, 11 points will be sampled. |
10.0
|
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. |
