Getting error while reading potential file

Hello, everyone.

I am using LAMMPS 64-bit 15Apr2020-MPI. I am using reaxff parameters taken from the literature that suits my system. While I am running the file with “pair_coeff * * ffield.reax.rdx C” simulation is running. But getting error when I am trying to read reaxff potential “pair_coeff * * ffield.Reax.latest C” from literature. Is there issue with the first line of the potential file as rest is same as .rdx file?

the rest is NOT the same. these are two different force field files for different purposes with different numbers of parameters.

the file you have from the literature is broken. it advertises to have parameters for 11 elements but contains data for 16.
that will cause the crash, since the parser reading the force field file assumes consistent data.
