Is the problem the function or the dataset I'm trying to use?

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

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

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

The function call should just be

mymain("DataSet.txt",5)

or

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