Plotting error in case of empty signature
Closed this issue · 1 comments

If for any reason the produced signature is empty, an error is raised in a plotting function.
How to reproduce this bug: simply set a high treshold (maybe higher than 1, for testing purposes), thus obtaining an empty signature (just check the signature_regular.txt file in the analysis subfolder) and then perform the analysis

I think now the bug is resolved.
I had the same problem, I fix it with a check if, inside the loop for each estimator, the signature extracted by that particular estimator is non empty.
In this way, if no variable is selected, simply continue with the other estimators.
