Hello,
I'm trying to restrain a molecule putting a force constant in column O of my pdb.
However, it seems that the original pdb file coordinates, the prmtop+inpcrd file coordinates,
and the coordinates coming from leap using savePdb are all different. I was then able
to use ambpdb with the prmtop + inpcrd files to create a pdb aligned with the prmtop + incprd.
So, I now have the proper reference file. When I sent to add the force constants to column
O, I discovered there was no column O or column B.
Can anyone tell me how I may generate a column O using ambpdb or any other way?
I don't know how vi can do it for example. I'm sure I can do an alignment in vmd and
save the coordinates from the orignal pdb file, but I was concerned with roundoff.
But is there a ambpdb way to do this?
Thanks.
