If your peptide has less than 400 atoms, you can also try and use the 'Fit
Ligand' option under the "Calculate" menu of the main window: read in the
coordinates of a peptide of the same length as the one you wish and use
"Simple Mutate" from the "Model/Fit/Refine" menu to adjust to the desired
sequence. Then choose "fit ligand" and click "flexible". That often works
amazingly well with decent density.
