Specific Interface Help

AccessFold
Bimolecular folding of nucleic acids without intramolecular pairs allowed. This program uses a heuristic to determine accessibility to to duplex formation.
AllSub
Generate all suboptimal nucleic acid structures within a small free energy increment of the lowest free energy structure.
bifold and bifold-smp
Bimolecular folding of nucleic acids with intramolecular pairs allowed.
bipartition and bipartition-smp
Bimolecular partition function calculation of nucleic acids without intramolecular pairs allowed.
CircleCompare
Compare two structures for the same sequence, with the nucleic acid backbone arranged around a circle to facilitate easy comparisons.
ct2dot
Generate a dot bracket file from a CT file. The CT file can be regenerated from the dot bracket file using dot2ct (below).
design
Find an RNA (or DNA) sequence that is expected to fold into a given structure.
dot2ct
Generate a CT file from a dot bracket file. The dot bracket file can be regenerated from the CT file using ct2dot (above).
