Object shape/dimensions can be found using the dim, ncol, and nrow functions; cell and feature names can be found using the colnames and rownames functions, respectively, or the dimnames function. Since feature names are not easily changeable in Seurat, I would recommend either creating a new Seurat object with the modified counts matrix or adding it as a new assay (see our multimodal analysis vignette for more details about working with multiple assays). We are closing this issue now as we are no longer prioritizing support for loom conversion. Second, as pointed out here by dev team in order to pull data from all applicable layers GetAssayData can be used to pull information from any of the expression matrices (eg. 0 and Seurat version is In reference to #26, GetAssayData() in predict_query.
