Changing a Tuple element (sequence) to sequence length (int)

I have this noob problem that im trying to fix but I cant

I have an array of tuples in the form of 

tuple: (string*(string*seq<string>)[])[]

I wish to convert the "seq" to the sequence length (int)

I tried in various forms with 

Seq.length

but I haven't been able to do it, can anyone help? thanks!

This function will map the nested sequence to its length:

let map arg : (string*(string*int)[])[] =
    arg |> Array.map (fun (s1, arr) ->
        s1, arr |> Array.map (fun (s2, coll) -> s2, Seq.length coll))

But seeing how complex the type you have there is, I wonder do you represent with it? You'd almost certainly want to use something more palatable then this.
