h1. PDB to Model

The user is able to retrieve pdb models from the Protein Data Bank and generate a 3D density volume from the atomic model. 

h2. To launch: 

# The user enters the PDB ID (and check on the "use biological unit" check box if desired)

# The user decides the resolution of the density model (typically filter to 15 - 25 Angstrom resolution)   

# The user selects the symmetry of the model

# The user selects the pixel size for the model

# The user selects the box size. Note: the user needs to make sure that the box size is sufficiently large to accommodate the 3D volume to be generated.

h2. Output:

# Once the model is generated, it will be deposited under "3d Density Volumes"

# The user then assess the quality of the model and decides whether to convert the volume into an initial model
