Error message "subscript out of bounds" in create_domino function

[LLi-jie]

Hi, I am using the create_domino function with the following parameters: signaling_db, features, counts, z_scores, clusters, and df. When I run the function, I encountered the following error message:

"Error in dom@features[feat, cells] : subscript out of bounds"

I am not sure what this error message means and how to fix it. Can anyone help me understand what went wrong and how to resolve this issue? Here is the code snippet I used:

KF_dom = create_domino(signaling_db = '~/domino/SCENIC/cpdb/', features = auc, counts = counts, z_scores = z_scores, clusters = clusters, df = 'KF_regulons.csv')

I suspect that the error may be caused by the cell sample names in my Seurat object, which contain "_". This may have caused the create_domino function to fail to read the data properly. However, I am not sure how to verify this hypothesis or what other possible causes may exist. I would greatly appreciate any suggestions or help on this issue.
Any help or suggestions would be greatly appreciated. Thank you!
