Hi,

I wonder if I will be able to arrange (i.e. descending order) the feature genes based on either ‘logfoldchanges’ or ‘pvals\_adj’ instead of ‘pvals’. Could you please give me a piece of advice?

result = adata.uns[‘rank\_genes\_groups’]  
groups = result[‘names’].dtype.names  
pd.DataFrame(  
{group + ‘\_’ + key[:1]: result[key][group]  
for group in groups for key in [‘names’, ‘logfoldchanges’, ‘pvals\_adj’]}).head(30)

Thank you in advance for your kind help…!

I’d recommend using the function [`sc.get.rank_genes_groups_df`](https://scanpy.readthedocs.io/en/stable/generated/scanpy.get.rank_genes_groups_df.html), and then to sort the resulting dataframe however you’d like.

I believe the ordering of `pvals` should be the same as the ordering of `pvals_adj`.
