Edit: Nvm this answer, see answer below.

~~Ah, I didn’t look at the sample file and didn’t notice you needed that big numbers. It probably makes sense to write your own little parser function then like~~

```julia
function read_data(s) 
    joined = join(split(s))
    no_brackets = SubString(joined, nextind(joined, 1), prevind(joined, lastindex(joined)))
    return parse.(BigInt, split(no_brackets, ','))
end

```

```julia
julia> read_data(s)
150-element Array{BigInt,1}:
