I want to use a seurat normalization method on a scRAN-seq dataset, specifically the integration method they use to normalize across differnt species or datasets. Tutorial is here. Seurat objects store data in a sparese matrix and after the integration I am not performing the clustering I am using it for another purpose and I need it as a regular dataframe. How can I pull the sparse matrix out as a regular dataframe? In case this wasn't clear I am using R.
