Dear QE users,
My final goal is to obtain phonon dispersion of Ti3C2, however at the very 
beginning I get the following error:
Error in scalartorealdpToo few elements found

Here is my input:

I assume there is something wrong with pseudopotentials but could not figure 
how to solve it. Could you please point out the problem.
Thanks,Ali
