SpaceWalker is a visual analytics tool for exploring the local gradient structure of 2D and 3D spatial transcriptomics data.
The interactive exploration of localized gene expression gradients is particularly interesting for tissue biology, as spatial gene expression gradients often represent tissue compartment edges, whereas in the HD single-cell transcriptomic domain, they represent cell-type differences and smooth phenotypic transitions between them.
For details and the software, please visit the SpaceWalker GitHub page and read publication by Li et al. (2023).
