Why is the number of DEGs output by FeatureHeatmap largely lower than that obtained from RunDEtest?

Hello, SCP team,

I have two unresolved questions and would appreciate your guidance.

Firstly, I noticed that the FeatureHeatmap generates a heatmap with a very small number of genes. As you can see, I obtained 1043 DEGs. Has any adjustment been made in FeatureHeatmap? How can I address this issue?

Secondly, every time I run the RunDEtest function, the output displays a warning message: "Warning in serialize(data, node$con): 'package:stats' may be unused when loaded." What could be the reason for this warning? Is it related to my Windows system? Does it affect the program's speed?

Thank you very much for your response.

Sophia
