perb_score in the output

[sunnysunnygood]

Dear authors,

Thanks for your amazing tools of scRank!

May I have your guidance that if the results should mainly focus on the rank or the perb_score?

_

As when trying the example in the tutorial, the results shows as below, the resistant cell type rank to be 1st, while the perb_score is lower than the sensitive cell types, which rank to be 2nd.

_

Besides, is there an threshold for the perb_score, 1.01e-6 seems quite small....

Thank you very much for your guidance! Appreciate!

Hi, thanks for your feedback.

1. The rank column is an intermediate variable that reflects the sample ranks of perb_score and can be ignored. The actual ranking of cell types is represented by the top_rank% column.

2. The small perb_score is due to the nature of the adjacency matrix in the manifold alignment analysis, where values range from 0 to 1, and involve the computation of smallest eigenvalue of the Laplacian matrix.

3. When interpreting results, it should focus on the top_rank% of cell types rather than the absolute values of perb_score, as there isn't a fixed threshold suitable for every case.
