Cellxgene VIP snRNA-seq demo dataset for visualization and DE analysis

H5ad file can be used as demo input for Cellxgene VIP. Dataset was the re-process from Schirmer et al Nature 2019 paper by using the raw fastq files. In order to reproduce the h5ad file, details could be found in https://github.com/interactivereport/cellxgene_VIP/blob/master/notebook/MS_Nature_Rowitch_snRNAseq.ipynb 
Two rds files are also included here which are the input files for sample differential expression (DE) analysis scripts (glmmTMB and Nebula)
