I really need Help!!!!!!!!!!!!!

I am so new at this, maybe I didn't ask the right question. Can ground pecans be used in place of almond flour, or ground up almonds??????? Like I said in a previous thread, I bought some ground of pecans because the store didn't have ground almonds (almond flour). I plan to get some almond flour as soon as I can. In the mean time, can I use the ground up pecans instead, for muffins etc.??????????
