Hello!
When I use scTE, I have some questions about the number of cells of the results.
I ran cellranger as the code below:
cellranger count --id ${sample} --sample ${sample} --transcriptome ~/dm6_cellranger --fastqs ./ --localcores 20
and I ran scTE as the code:
scTE -i ${sample}/outs/possorted_genome_bam.bam -o ${sample} -x ~/dm6.exclusive.idx --hdf5 True -CB CB -UMI UB -p 24
When I analysed the results with Seurat, I found cellcounts of the two results are not consistent.
Convert("sample.h5ad", dest = "h5seurat", overwrite = TRUE)

Seurat.obj
An object of class Seurat
3113 features across 1545 samples within 1 assay
Active assay: RNA (3113 features, 0 variable features)
2 layers present: counts, data
obj <- Read10X(data.dir = "sample/")Seurat.obj2 <- CreateSeuratObject(counts = obj, project = "sample", min.cells = 3, min.features = 200)Seurat.obj2
An object of class Seurat
12338 features across 7958 samples within 1 assay
Active assay: RNA (12338 features, 0 variable features)
1 layer present: counts
As the results show, scTE result has 1545 cells but the cellranger result has 7958 cells. I wonder whether I have made anything wrong, thus resulting the difference.
