The issue appears to be with trying to read in the file _twice_ , that is , when you set

```julia
info = readdlm("DataSet.txt")

```

you get a Julia object, like you said, a `30×6 Array{Float64,2}`. So the effective result inside the function is

```julia
M = readdlm(readdlm("DataSet.txt"))

```

The function call should just be

```julia
mymain("DataSet.txt",5)

```

or

```julia
info_filename = "DataSet.txt"
mymain(info_filename,5)

```
