Introduction

Dr. Forna is a web component for visualizing co-transcriptional RNA folding.

As input it takes a space separated values (ssv) file:

id time conc struct energy
1 0.340000 1.000000 .................   0.00
1 0.360000 1.000000 ..................   0.00
1 0.380000 1.000000 ...................   0.00
2 0.380001 1.537182e-03 .(((.((((...)))).)))  -3.60
1 0.380001 9.984628e-01 ....................   0.00
2 0.38000274542 4.214534e-03 .(((.((((...)))).)))  -3.60

2 0.38000753733 1.152803e-02 .(((.((((...)))).)))  -3.60
1 0.38000753733 9.884720e-01 ....................   0.00
2 0.38002069313 3.133086e-02 .(((.((((...)))).)))  -3.60
1 0.38002069313 9.686691e-01 ....................   0.00
2 0.38005681134 8.367606e-02 .(((.((((...)))).)))  -3.60

Where id groups structures, time is the time point for which the structure and the concentration are measures. conc is the occupancy of that structures at that time point. The secondary structure is encoded as a dot-bracket string in the struct column while the free energy (in kcal / mol) is shown in the energy column.
