ASHLAR: Alignment by Simultaneous Harmonization of Layer/Adjacency Registration
--------------------------------------------------------------------------------

**Whole-slide microscopy image stitching and registration in Python**

**Ashlar** performs fast, high-quality stitching of microscopy images. It also
co-registers multiple rounds of cyclic imaging for methods such as CyCIF and
CODEX. Ashlar can read image data directly from BioFormats-supported microscope
vendor file formats as well as a directory of plain TIFF files. Output is saved
as pyramidal, tiled OME-TIFF.

Note that Ashlar requires unstitched individual "tile" images as input, so it is
not suitable for microscopes or slide scanners that only provide pre-stitched
images.
