Setting

  • Dataset: DLPFC 151675 window - DLPFC 151675 window

  • Window type: overlapping irregular window

  • Layer-wise accuracy: 100% and number of aligned spots consistent with ground truth


Spatiotemporal trajectories across developmental stages

Spatiotemporal trajectory inference

Setting

  • Dataset: Stereo-seq mouse midbrain from E12.5 to E14.5 and from E14.5 to E16.5. Cells are colored by the expert annotations from original study: RGC, radial glia cell; GlioB, glioblast; NeuB, neu- roblast

Spatially preserving analysis of cell-cell communication across slices

Cell-cell communication

Setting

  • COMMOT(https://commot.readthedocs.io/en/latest/) is applied independently to each slice to infer cell-cell communication (CCC). CCC inferred on slice A is transferred to slice B using the RAFT-UP spot-to-spot mapping, enabling direct comparison to CCC inferred on slice B, and vice versa
