merge function in the seurat

[zqsha]

Question1: When I merge two seurat data by using
brain <- merge(brain1, brain2)
It shows the following error
Error in .rowNamesDF<-(x, value = value) :
duplicate 'row.names' are not allowed

Question2: Previously, I use SCE to run the spatial transcriptomic data. But now I converted SCE into the SEURAT using
brain1 <- as.Seurat(sce1, counts = "counts", data = "logcounts")
But, I found the image data can not be converted into SEURAT. The image data is in the sce1@metadata. I want to convert it into the seurat data, i.e., brain@images. Any suggestions?
