There is no residue named Ni in the pdb used. This was one reason I
was confused.
This is the procedure I used to assemble my model:
1. I made a CR unit by creating the "crown" portion in antechamber,
loading it into xLeap and saving it as a unit. I created a unit called
Ni and saved it. I loaded a pdb with the CR and the Ni, merging them,
added the Ni bonds and saved it as NCH.
2. I then loaded a pdb for a piece of DNA with two of the atoms from
NCH (the CR portion) in it (labeled as the correct atom names and
residue name NCH).
I'm wondering if, when I made the NCH from the two portions and then
saved it, did it not re-name the entire unit? Or is it still named as
if it's made up of the smaller units? Which name/names would I use in
my pdb?
I do understand about renaming the pdb file to exactly match the unit
in leap and have gotten it to work with a different unit and this pdb
for the DNA without a hitch. That unit was a single unit created in
antechamber (no merge afterward).
I guess my main question is, how do you rename a new unit (made up of
other units) and use that new name in a later step?
Thank you for your help,
Kara Di Giorgio
p.s. I'll try to make my questions more clear in the future.
