Protein Ribbon Diagrams
Parse PDB files and render ribbon diagrams of proteins in pure Go.
Go should be installed and your
GOPATH should be set (defaults to
$HOME/go in Go 1.8+).
$GOPATH/bin should be on your
$PATH if you want to run the binaries easily.
$ go get -u github.com/fogleman/ribbon/cmd/rcsb
Provide a 4-digit RCSB Structure ID. The PDB file will automatically be downloaded and an image will be rendered. The triangle mesh will also be saved.
$ rcsb 4hhb # generates 4hhb.png and 4hhb.stl
RCSB Protein Data Bank - Find PDB files of proteins here. Over 100,000 in the database.
PDB File Format - Details on the PDB file format.
pdb package parses PDB files. The following entities are currently parsed:
ATOM => *pdb.Atom HETATM => *pdb.Atom CONECT => *pdb.Connection HELIX => *pdb.Helix SHEET => *pdb.Strand BIOMT => pdb.Matrix SMTRY => pdb.Matrix
Additionally, some higher-level constructs are produced:
ribbon package generates 3D meshes given a
pdb.Model. It can produce the following types of meshes:
- Ball & stick (for ligands)
- Space filling
The fauxgl library is used for rendering the 3D meshes in pure Go.
