    Here, the DBIT-Seq data does not have any image, whereas the mIF +does. However, we can use the registerSpatialData +function to warp/align a collection of observations to another +collection or an image. Since at least one VoltRon object is missing its +image, the resulting alignment can only be performed manually. Thus we +select landmark points and perform an affine or homograph +transformation.

    +


    -

    We can now combine all sections into one VoltRon object. There are -two pairs of serial tissue sections, but both pairs (thus 4 sections) -are from the same tissue block. Hence, we can combine these two lists -into one list and merge VoltRon objects even though sections were -aligned separately.

    Single Cell Integration

    +

    VoltRon supports the integration of VoltRon objects with Seurat or +SingleCellExperiment objects to facilitate the integration of spatial +and single cell omic data modalities. This integration enables both the +transfer of features from the scRNA data that are originally not +available in the spatial assay, or the transfer of annotations from the +scRNA data that serves as a single cell omics reference.

    +

    As the scRNA reference, we will use the 10x single cell FFPE dataset +(GSE243275) generated from the same tissue block as the Xenium +experiment. You can find the single cell data here.

    +

    We first import the scRNA data as a Seurat object and we also +normalize the profile of each cell.

    +
    if (!requireNamespace("Seurat", quietly = TRUE))

    +seu <- Seurat::CreateSeuratObject(seu)
    +seu <- Seurat::NormalizeData(seu, scale.factor = 10000)
    +

    To transfer the features of scRNA to the VoltRon object, we use the +transferData function. If no features are provided, all +features from the scRNA object will be transferred. After the transfer +is complete, a new feature set for the target VoltRon assay will +appear.

    +
