Your workflow The analysis runs in nine stages, each with several methods. Select your experiment to see which methods it uses. Segmentation Cells with morphology, not just nuclei Segment from any channel on which cell outlines can be made out: antibody-derived stains such as CD45, NeuN, IBA1, GFAP and DAPI, or H&E and haematoxylin. Combine several markers for one segmentation and add a nucleus channel if you like. The result keeps branching and process morphology, so morphometric features of neurons and glia stay measurable. - Multi-marker segmentation - Nuclear and membrane channels - Neuron and glia morphology - Whole slide, no tiling artefacts Registration Elastic alignment at any size Correct complex local deformation across consecutive staining cycles, across different protocols on the same section, and across consecutive physical sections. Sectioning, hydration and shearing deform tissue locally, and a rigid or affine alignment cannot correct that. Elastic registration can, at any image size, which keeps cross-talk out of the marker table. - Cross-cycle and cross-protocol - Cross-section alignment - Any image size - Proteomics and transcriptomics in one frame Phenotyping Gate, cluster, compare Combine manual gating, automated clustering and marker-independent tissue segmentation to group cells into phenotypes that mean something biologically. Then go past the cell table: shape, size, branching, neighbourhood composition and distance to lesion are measured per cell, so comparisons across conditions and cohorts use tissue architecture. - Manual and hierarchical gating - Automated clustering - Tissue-level segmentation - Morphometric features per cell - Neighbourhood composition and distance to lesion - Comparison across conditions and cohorts Neuropathology Aggregates, classified and put in context Classify pathological protein aggregates of amyloid β, phospho-tau, α-synuclein and TDP-43, and characterise the cells in their microenvironment. Dense-core versus diffuse plaques, tangles versus neuropil threads. - Aggregate classification - Plaque and tangle subtypes - Microenvironment characterisation - Region-level statistics Custom models When the pre-trained model is not enough Annotate a small region of your own tissue, train a segmentation model on it, and use it alongside the pre-trained ones. Every training run keeps its loss curve, accuracy and sample count, so you always know which model produced a result. - Train on your own stain - A few dozen annotations to start - Auditable training runs - Apply to a whole cohort Formats and instruments Instruments Akoya Phenocycler · Bruker Spatial Biology CosMx and CellScape · Lunaphore COMET · 10x Genomics Visium, Visium HD and Xenium · Vizgen MERSCOPE File formats OME-TIFF · TIFF series · Zeiss CZI · Leica LIF · dense image stacks and sparse coordinate lists.
