[AMBER] Warning regarding "triangular bond"

Hey friends,


I have gotten some warnings when using tleap. Here it goes:


1-4: angle 2656 2657 duplicates bond ('triangular' bond) or angle ('square' bond)

1-4: angle 2655 2657 duplicates bond ('triangular' bond) or angle ('square' bond)

1-4: angle 2655 2656 duplicates bond ('triangular' bond) or angle ('square' bond)

I checked the prmtop file and found that the water molecules I added all looked like triangles. (meaning the two Hs also bonded to each other)

Then I tried to follow the Amber Tutorial on using antechamber to do a trial to see where I went wrong. Surprisingly, I realized that this error is also shown on the tutorial web-page!

1-4: angle 7 12 duplicates bond ('triangular' bond) or angle ('square' bond)

1-4: angle 7 9 duplicates bond ('triangular' bond) or angle ('square' bond)

1-4: angle 9 12 duplicates bond ('triangular' bond) or angle ('square' bond)

Could anyone help me in dealing with this problem? Or if this error can just be ignored?

Many thanks!

Jiawei
