tomwer.core.process.reconstruction.axis.axis.AxisTask

class tomwer.core.process.reconstruction.axis.axis.AxisTask(process_id=None, varinfo=None, inputs=None, node_id=None, node_attrs=None, execinfo=None)

Process used to compute the center of rotation of a scan

Parameters:

axis_params – parameters to configure the axis process

Type:

AxisRP

compute(scan, wait=True)

Compute the position value for the scan

Parameters:

• scan (TomwerScanBase) –

• wait (bool) – used for threaded process. True if we want to end the computation before releasing hand.

Returns:

scan as a TomoBase

compute_axis_position(scan)

Parameters:

scan – scan for which we compute the center of rotation

Type:

TomoScan

Returns:

position of the rotation axis. Use the .AxisMode defined by the .ReconsParams of the .AxisProcess

Return type:

float or None (if fail to compute the axis position)

define_calculation_mode(mode, fct_pointer)

Register the function to call of the given mode

Parameters:

• mode (AxisMode) – the mode to register

• fct_pointer – pointer to the function to call

static definition()

definition of the process

static get_cor_frm_process_file(process_file, entry, as_url=False)

Read cor position from a tomwer_process file

Parameters:

• process_file –

• entry –

Return type:

Optional[float]

Returns:

static get_inputs(scan)

static get_inputs_urls(scan)

Make sure we have valid projections to be used for axis calculation

Parameters:

scan (TomwerScanBase) – scan to check

Raise:

NoAxisUrl if fails to found

Returns:

the two projections to be used for axis calculation

Return type:

tuple of AxisResource

lock_position_value(lock=True)

lock the position currently computed or defined by the user. In this case we will lock the axis as defined ‘fixed’ with the current value

Parameters:

lock (bool) – if true lock the currently existing position value

static program_name()

Name of the program used for this processing

static program_version()

version of the program used for this processing

run()

Compute the position value then get ready to the next. And call

Note

this simply call compute. But this is needed for the AxisProcessThreaded class

setMode(mode, value)

set_configuration(configuration)
