Hi Roja,
Did you mean bonding information like atom parameters missing which is
missing for some atom types? In that case, you can add amber=Hardfirst in
the root section of your input and add the parameters at the end (below the
connectivity table using HrmBnd1 or HrmStr1 according to your need). Find
the attachment for parameter data.
