NEW FEATURES
build_SpatialExperiment() (and add_array_coords()) takes a new parameter algorithm whose default is now "LSAP". The older implementation is available via the "Euclidean" algorithm. The now LSAP approach is a significant improvement in how new array coordinates are assigned, preventing all duplicate and most empty mappings within a single capture area, leading to improvements in downstream applications like clustering.NEW FEATURES
visiumStiched package that provides utilities for
stitching together Visium capture areas and enables seamless downstream
spatially-aware clustering methods to identify clusters on the stitched data.
An example postmortem human brain dataset composed of 3 Visium capture areas
was generated to demonstrate the utility of visiumStitched. The dataset is
available from spatiaLIBD::fetch_data() version 1.17.8 or newer. The example
data is described at https://research.libd.org/visiumStitched_brain/.
