modify_as_job(remove=None, replace=None, keep=None, force=False, remove_private_tags=False, keep_source=True, priority=0, permissive=False, private_creator=None)

Modify series and return a job

Launch a modification job. If keep=['SeriesInstanceUID'] (with force=True), then modified this series. If the SeriesInstanceUID is not keeped, this creates a new modified series. Documentation: https://book.orthanc-server.com/users/anonymization.html

Notes

This method is useful when modifying large series or launching many modification jobs. The jobs are sent to Orthanc and processed according to the priority.

Parameters:

Name	Type	Description	Default
remove	List	List of tag to remove	None
replace	Dict	Dictionary of {tag: new_content}	None
keep	List	Keep the original value of the specified tags, to be chosen among the SeriesInstanceUID, SeriesInstanceUID and SOPInstanceUID tags. Avoid this feature as much as possible, as this breaks the DICOM model of the real world.	None
force	bool	Allow the modification of tags related to DICOM identifiers, at the risk of breaking the DICOM model of the real world.	False
remove_private_tags	bool	If True, remove the private tags from the DICOM instances.	False
keep_source	bool	If False, instructs Orthanc to the remove original resources. By default, the original resources are kept in Orthanc.	True
priority	int	Priority of the job. The lower the value, the higher the priority.	0
permissive	bool	If True, ignore errors during the individual steps of the job.	False
private_creator	str	The private creator to be used for private tags in Replace.	None

Returns:

Type	Description
Job	Return a Job object of the modification job.

Examples:

For large series (recommended)

job = series.modify_as_job(replace={'SeriesDescription': 'a description'})
job.state  # You can follow the job state

job.wait_until_completion() # Or just wait on its completion
modified_series = Series(job.content['ID'], client)
assert modified_series.description == 'a description'

Or modify the SeriesInstanceUID

job = series.modify_as_job(
    replace={'SeriesInstanceUID': '1.2.840.113745.101000.1008000.38048.4626.5933732'},
    force=True
)
job.wait_until_completion() # Or just wait on its completion

modified_series = Series(job.content['ID'], client)
modified_series.uid == '1.2.840.113745.101000.1008000.38048.4626.5933732'

Or keep the SeriesInstanceUID

job = series.modify_as_job(
    replace={'SeriesDescription': 'a description'},
    keep=['SeriesInstanceUID'],
    force=True
)
job.wait_until_completion()

assert series.description == 'a description'

    -----
    This method is useful when modifying large series or launching many
    modification jobs. The jobs are sent to Orthanc and processed according
    to the priority.

    Parameters
    ----------
    remove
        List of tag to remove
    replace
        Dictionary of {tag: new_content}
    keep
        Keep the original value of the specified tags, to be chosen among the SeriesInstanceUID,
        SeriesInstanceUID and SOPInstanceUID tags. Avoid this feature as much as possible,
        as this breaks the DICOM model of the real world.
    force
        Allow the modification of tags related to DICOM identifiers, at the risk of breaking
