Hi, Yasir-
I am not sure how the Lempel-Ziv complexity could be calculated here? From looking on (a somewhat poorly worded entry in) wikipedia, it looks like that relates to a binary sequence. I am not show that applies to FMRI (time series or power).
For fSD, that is also something I am not familiar with. How do you see the errors and multiple components/entries there? That is, how are you parcellating your problem, and assigning the sub-errors of each?
Also, I am curious how these quantities relate to brain imaging---what biological or data-interpretational meaning do they have? Sorry, I just have no experience with them.
