[Ifeffit] Help--save k(q) data in larger k range

Hi, I was trying to save my data in k(q). I set the k-range for fourier transform, and r-range for the inverse fourier transform, and was able to see the resultant k(q) figure in whatever k-range I want. But when I hit “save in k(q)”, in the generated file I could only get the data in a k-range of 0-8. Is there a way to get the data in a larger k-rang, e.g., 0-15? Thanks!
