Dear All,
I need to simulate the behaviour (with 3D visualization) of many arbitrary designed variable sized single stranded DNA in solution. This includes double helix formation among single stranded DNA, hairy pin in one single stranded DNA, etc.
I am new to 3DNA and I would like to know if it is possible to do what I need with this software. If not, what would you suggest ? Probably any kinetic Monte Carlo implementation around ?
Kind regards and many thanks in advance.

With 3DNA, you can build a straight single-stranded DNA (ssDNA) of arbitrary sequence using fiber as shown below:
fiber -seq=aaatttt -single fb.pdb
or a sequence-dependent ssDNA structure by providing a sequence and associated step parameters.
Note that 3DNA's model building facility is purely geometry-based, employing base-pair parameters, and it takes no consideration of energetics. Overall, you may find 3DNA useful in certain aspects of your project, and need to try other tools (e.g., NAB/AMBER etc from the Case lab (http://casegroup.rutgers.edu)) as well.
HTH,
