asSeurat() returns "character" and warning in SPATA2 3.1.4

[jligm-hash]

Here’s a concise issue body you can paste and adapt:

Description

asSeurat() does not return a Seurat object in SPATA2 3.1.4. It prints a warning that the function is in development and the returned object has class "character" instead of "Seurat".

Minimal reproducible example

r
library(SPATA2)
library(Seurat)

packageVersion("SPATA2")
# 3.1.4

data("example_data")
object <- example_data$object_UKF275T_diet

seurat_obj <- asSeurat(object)

class(seurat_obj)
# "character"

Console warning:

r
Warning in asSeurat(object): This function is currently in development.
Please raise an issue at github if you require SPATA2 to Seurat conversion.
Expected behavior

asSeurat() should return a valid Seurat object (e.g. class "Seurat") containing the expression matrix, metadata, and spatial information for the SPATA2 object.
