Is the Expression Matrix Preprocessed?

Hello–

I have downloaded the expression matrix of the WHOLE CORTEX & HIPPOCAMPUS - 10X GENOMICS dataset. In the protocols, there are some steps that explain the quality control of the raw count data. My question is, has the expression matrix passed those quality control steps, or are these step taken only for the generation of the clusters? Otherwise, researchers will need to do the quality control before utilizing the dataset (doublets detection, …)

Thanks,

The available count matrix for the WHOLE CORTEX & HIPPOCAMPUS - 10X GENOMICS dataset has been processed and passed QC.
