Description of work

If the user performs pixel calibration, but sees that it did not do anything positive, allow the user from the tweak peak stage to elect to skip pixel calibration and recalculate.

Explanation of work

After all the other changes, this was very trivial.

Add a new button to tweak peak view for skipping pixel calibration, and add a check if the user changes their initial selection.

If the initial selection changes, recalculate with/without pixel calibration.

To test

Dev testing

Run diffraction with 46680, skip pixel toggle set to False.

It should fail. In the workspace list, open the two table workspaces, diffract_consts_default_v0 and diffract_const_046680. Compare, and ensure these are not equal workspaces.

Right-click on diffract_const_046680 and rename it to something obvious so that it is not overwritten.

Set Skip Pixel Cal toggle to True and continue. There may be a warning about a workspace already loaded.

Set Skip Pixel Cal toggle to False and press Recalculate. The same warning will come up. Close it.

Compare the new diffract_const_046680 to the original. They should be identical. This proves the workflow is being re-run without skipping pixel calibration.

Change the grouping and recalculate. Make sure it works.

Change the grouping and a dMin and recalculate. Make sure it works.

Change only a dMin and recalculate. Make sure it works.

Continue to save. You'll have to set Skip Pixel Cal to True and change the FWHM to 4 and Recalculate to continue.

CIS testing

As above, but I suggest 58882. Make sure to inspect the before/after files in slice viewer. Make sure you can find them and they make sense.

Acceptance Criteria

This list is for ease of reference, and does not replace reading the EWM story as part of the review. Verify this list matches the EWM story before reviewing.

NOTE Following conversation with Malcolm, the behavior of iterating pixelcal is not necessary as there are no parameters to adjust.

• after pixel calibration, user has available two d-spacing unfocussed workspaces reflecting separately the input calibration and the output calibration (i.e. application of the pixel-calibration-generated DIFC values). already met in PR After completion of pixel calibration, show unfocused before and after  #511
• The user can continue to next stage of workflow if desired already met
• Or, the user can repeat pixel calibration, opting to completey reset DIFCs to their original values
• The user has access to a UI element to select from the above options
• The user can repeat pixel calibration an arbitrary number of times (note: they can, but it doesn't do much)
• Conducting N iterations, where N>2 should not cause further increase in RAM usage
