The input raw count matrix has negative values. The core of the problem was introduced by the cell bender v0.3.0-v0.3.1
discussion broadinstitute/CellBender#306
Hi,
I am using Seurat 5, parsing h5 files generated with Cell Bender and creating a Seurat object with count matrices ( 8 samples - 8 count matrices) , which are stored as layers in Seurat 5. When I run FindVariableFeatures() function I am getting an error, which is inconsistent it occurs for different samples. So sometimes it raises for sample S25 another time it manages S25, but occurs in another sample S45, or L55 etc.
Never had this error before, and also checked: #2387 suggested solution doesn't help as I Normalise data and also do DefaultAssay(object = cell_bender_seurat_filt) <- "RNA"
cell_bender_seurat
An object of class Seurat
36601 features across 48313 samples within 1 assay
