I'm assuming you have read carefully Section 3.2.2 of the Amber14 Reference
Manual. We are working to make this clearer in the upcoming (April) revision.
The chi(OL4) term is not in the "standard" (leaprc.ff14SB) force field.
I thought that the files for "ff99 + bsc0 + e/zOL1 + chiOL4" had been posted
somewhere, but I can't find them right now. These will also be in the
upcoming release, and maybe someone on the lists knows where they are now.
