[modeller_usage] interpolating missing residues

Hi, All:

I was trying to add missing residues in pdb file according to the page:

http://salilab.org/modeller/wiki/Missing%20residues

But, one thing I don't understand is how can I get the "alignment.ali" file?

Aslo, it seems to me the command complete_pdb() can also do the job? http://salilab.org/modeller/manual/node403.html Is this true? If so, what's the difference between these 2?

Thanks a lot. Bin
