Inaccurate results of multi-dimension motif discovery using MSTUMP #368

Based on Matrix Profile VI Paper and Stumpy Documentation (Tutorial-Mutlidimensional Motif Discovery) of the same, I'm trying to identify Multi-dimensional Motifs from PRONTO Dataset.

After a bit of preprocessing of the data, and calculating multidimensional matrix profile, I plot the Elbow Curve as suggested in the tutorial. Based on the curve k=8 dimensions out of 31 are relevant.

When I plot the motifs after selecting the varibels using MP subspace, and I get the following result. Now, even though there are aligned motifs, but not all of them are aligned.

Even when I try with subset of variables I get misaligned motifs.
