How do i get inverse wavelet transformation (icwtft) from my new coefficients values?

Hi,

I want to do a inverse continous wavelet transformation (icwtft). I have taken a simple sinewave function and got wavelet transformation with reconstructed signal with the matlab example (cwtft help). but i done some prediction values on sinewave cwtft file and got has a new coefficients file (cfs) only and format is .csv file. but the problem is, how can i create scales and their frequencies or other parameters (required parameters) w.r.to the news coefficient values (cfs). I would like to see with these new coefficients reconstructed signal. please kindly let me know any ideas or suggestions. i tried it in different ways but not successful. Thanks in advance.
