I had 6 treatment and 6 control samples which were sequences on Illumina. I used the cell ranger --count function to sequence all of my samples together since they were sequenced on the same platform. It gave me a bunch of outputs from which I used a raw.h5 file to generate a Seurat object which didn't work. I used the Read10x_h5 function from Seurat in R which did read the file however when I used the CreateSeuratObject function to make suerat object it gives me the following error

"$ operator not defined for this S4 class"

so I used str function to take a look at the class. and the only thing I was able to see was as follow
