I would to like add that this error  is related to reed solomon encoder. 

If I usen n = 15 and k = 11, it works fine. But if I use n = 64 and k = 32, it does not work and gives error.

Can anyboody guideme how to fix it.

Hello JK,

You have entered an invalild n value. As the error explains, “The relation n-k=2*t (where t is the error correcting capacity in symbols) must be satisfied for any valid RS code. For a "normal" RS code, n must be a valid power of two minus one."

n = 15 works, since log2(15+1) = 4, and 4 is an integer number.

n = 64 does not work, since log2(64+1) = ~6.022367, and ~6.022367 is not an integer number.
