Protein Backbone Panel - CONNJUR/CONNJUR_widgets GitHub Wiki

The Protein Backbone Panel is a GTK/cairo widget for highlighting the atoms observed in a given NMR experiment.

The drawing code is broken into four blocks.

  1. Data structures for the backbone atoms are created.
  2. Coordinates for each atom are calculated keeping the HN in the center.
  3. The backbone scaffold is drawn.
  4. Atoms are drawn on top of scaffold.

Coloring of the atoms is customized by passing a data structure for that purpose.

Example code is shown below: 

AtomColor myColor = getAtomColors(varianPars.seqfil);
GtkWidget *drawArea;
drawArea = GTK_WIDGET(gtk_builder_get_object(builder,"drawingarea1"));
g_signal_connect (G_OBJECT(drawArea), "draw", G_CALLBACK(backbone_callback), &myColor);

Code for this widget is found at: https://github.com/gryk/CONNJUR_spike/tree/master/cjrShowVarian
