LMP7721 simulation with Tina-TI

Hi,

I am a Mechanical Engineer and doing some low current simulations in Tina-TI for LMP7721 Op-amp. When I use the LMP7721 as a trans-impedance config with 1T feedback resistor (to measure 1p or lower current), solution doesn't converge. I changed the Analysis parameter for low current measurement as Paul suggested in earlier forum post. I have attached my Tina-file here.

Appreciate if some one can give me an idea, what I am doing wrong here.

Thanks
