Hi,

Thank you for the great work!

I have a question regarding the two-step rotation process described in your paper, specifically the use of ICA and Varimax rotations. In the code implementation for the hybrid rotation, I noticed that the Varimax rotation is applied to the core tensor, with counter-rotation applied to the donor matrix. However, I was wondering whether the counter-rotate the core tensor in ICA step, mentioned in your paper, is implicitly included in the process, as it does not appear explicitly in the code.

I would greatly appreciate any insights you could share on this.

Thanks!
