Conversion to Seurat fails when a dimension is 0 #357
Description
Example:
library(anndataR)
adata <- AnnData(X = matrix(nrow = 10, ncol = 0))
adata$as_Seurat()
#> Warning: No "counts" or "data" layer found in `names(layers_mapping)`, this may lead to
#> unexpected results when using the resulting <Seurat> object.
#> Warning: Data is of class matrix. Coercing to dgCMatrix.
#> Error: No feature overlap between existing object and new layer dataCreated on 2025-09-25 with reprex v2.1.1
