The example expression matrix we provided here is a normalized example. In most scenarios, users are encouraged to preprocess raw count outputs of their sequencing data. Considering the features of scRNA-seq data, we suggest that users may follow the pre-processing code below to achieve the best performance on their scRNA-seq raw counts. The log-transformation is always suggested to avoid heavy-tailed datasets.
