[AMBER] Solvate with SPC/Fw water

Hello,

I’m running into an error when relaxing a system solvated with SPC/Fw water model. In the first step (energy minimization of added water and ions), the job stops with:
Error: Fast 3-point water residue, name and bond data incorrect!

tleap completed without fatal errors and produced rst7 and parm7 files, but I suspect something went wrong in how SPC/Fw waters were set up. I’ve attached my tleap input and tleap log. Could you please provide me some guidance for this issue?

Thank you,
Kiriko
