Some questions about data preprocessing. #7
Comments
Hi there, Thank you for your interest in our Portal method! In Portal, we select highly variable genes with flavor 'seurat_v3'. Count data is expected when using flavor 'seurat_v3', while logarithmized data is expected when using other flavors (https://scanpy.readthedocs.io/en/stable/generated/scanpy.pp.highly_variable_genes.html). Therefore, Portal selects genes before obtaining logarithmized data; while standard scanpy pipeline selects genes with another flavor using logarithmized data. Best, |
Your work is very interesting, and I would like to use portal-sc to conduct some tests on our dataset. And it's great to see the work you've done in
