`Array{Dict{Any,Any},1}` is a type and not an instance of a type. You
probably want:
allmeas[measkey]["manreps"][num_manrep]["autoreps"] = Dict{Any,Any}[]
this creates a vector which can hold `Dict{Any,Any}` of length zero. If
you know the length (==n) of the vector use this:
allmeas[measkey]["manreps"][num_manrep]["autoreps"] = Array(Dict{Any,Any},n)

If you knew the length, above works. However, if you have a zero-length
vector, use push! as (unlike in Matlab) you cannot use indexing to
extend arrays
push!(allmeas[measkey]["manreps"][num_manrep]["autoreps"], newmeas)
which adds this to the end of the vector.

That is a bit odd, I get:

DataType

Aside: to lighten the burden on your helpers and to ensure speedy
answers, try to make your examples as simple as possible, self
contained, and run-able with copy-paste. For instance, instead of
allmeas[measkey]["manreps"][num_manrep]["autoreps"]
just use a variable:
autoreps = Dict{Any,Any}[]
