dials.slice_sequence

Introduction

Slice a sequence to produce a smaller sequence within the bounds of the original. If experiments or experiments are provided, modify the scan objects within these. If reflections are provided, remove reflections outside the provided image ranges. Each image_range parameter refers to a single experiment ID, counting up from zero. Any reflections with experiment ID not matched by a image_range parameter are removed.

Examples:

dials.slice_sequence models.expt observations.refl "image_range=1 20"

dials.slice_sequence models.expt "image_range=1 20"

# two experiments and reflections with IDs '0' and '1'
dials.slice_sequence models.expt observations.refl     "image_range=1 20" "image_range=5 30"
