Re: [AMBER] loadpdb with GLYCAM_06 ?

Hi, I did put TER cards as:

HETATM 3381 C6 2hA C 5 -8.708 11.921 36.620 0.65 42.18
C
TER 2hA C 5
HETATM 3371 O OME C 6 -5.752 12.674 33.641 0.65 41.94
O

And I also used LINK as:

LINK O OME A 6 C1 2hA A 5
...

So I guess that's why it worked out.

Thanks again,

Yun
