Allow users to provide parameters in order to define a
start_angle_offset and a
angle_interval to create NXtomo split from pcotomo.
If provided It will apply a subselection once the NXtomo will be created.
note: this will simply upgrade the
image_control_key to INVALID
add NXtomo utils functions to do selections according to
stop_angle(see below API first point)
andangle_interval` (see below API second point)
add unit tests
add parameter in the HDF5Configuration file
apply sub-selection when requested from
add unit tests
test on a "real dataset"
fix #91 (closed)
NXtomo python API.
first point: add
function used to do a sub selection in a NXtomo according to rotation angle.
Only projections will be affected. If this needs to evolve then we could provide a
frame_type parameter (as a tuple) to know on which frame we should apply this selection.
To simplify (a lot) this will only affect the
image_key of the NXtomo. So the detector data will stay unmodified. This is not very intuitive but way simpler.
@staticmethod def sub_select_selection_from_angle_range( nx_tomo, start_angle: float, stop_angle: float, copy=True ): """ create a NXtomo like `nx_tomo` input but update `image_key_control` to INVALID for all projections which does not fulfill the condition: start_angle < rotation_angle < stop_angle Note: Darks and flat will not be affected by this sub selection :param float start_angle_offset: offset to apply to start the selection. Expected in degree. Must be signed. **The offset is always relative to the first projection angle value** :param float angle_interval: interval covered by the selection :param bool shift_angles: should we shift the angles of `-start_angle_offset` (once the selection is done) :param bool copy: if True then copy the nx_tomo """
second point: add
This is the function required for #91 (closed) This is applying sub_select_selection_from_angle_range with some pre processing (determine start_angle and stop_angle) and it is also able to shift (projection) angles
