This dataset contains the spatial transcriptome dataset of human gastric mucosa obtained by CosMx A zip file contains the following folders and files: Folders - CellComposite folder: the composite immunofluorescent images of each FOV. - CellLabels folder: the cell definitions images for each FOV determined during cell segmentation. - CellOverlay folder: the cell boundary images for each FOV determined during cell segmentation. - CompartmentLabels folder: the subcellular compartment images for each FOV determined during cell segmentation. The compartment types are as follows: 0. Extracellular, 1. Nuclear, 2. Membrane, 3. Cytoplasmic - RawMorphologyImages folder: raw morphological TIF images for each FOV Files - Run5458_{sample_name}_exprMat_file.csv: cell expression matrix. - Run5458_{sample_name}_fov_positions_file.csv: each FOV relative position within global structure. - Run5458_{sample_name}_metadata_file.csv: the metadata of each cell. - Run5458_{sample_name}_tx_file.csv: the transcript file for each target gene and its position. - Run5458_{sample_name}-polygons.csv: the segmentation polygon file.
