The data you pass to the first let is structured like this:
[[:a :b :c :d :e :f :g :h :i] [:j]]
i.e., a 2-vector with a 9-vector and a 1-vector in it.
But the data in cj-mpdata is structured like this:
[:a :b :c :d :e :f :g :h :i [:j]]
i.e., a 10-vector with a 1-vector as its last element.
In your second let case, doing this should work:
(let [[_ ck db cr _ dt _ _ _ [dsc]] cj-data]
[dt ck db cr dsc])
Also, adding square brackets to both the left hand side and the right and
side in a let binding is a no-op, and can be removed.
