SimRNAweb2.0


SimRNA

SimRNA is a method for RNA 3D structure modeling with optional restraints.
SimRNA uses (1) a coarse-grained representation, (2) relies on the Monte Carlo method for sampling the conformational space, and (3) employs a statistical potential to approximate the energy and identify conformations that correspond to biologically relevant structures.


What's new?

  1. Incorporation of diverse restraints: Users can now implement a broader range of restraints, encompassing both canonical and non-canonical base pairs, and unpaired residues, as well as data from chemical probing experiments.
    • Soft restraints on secondary structure [Dec. 2023]
    • Hard restraints on base pairs [Dec. 2023]
    • Soft restraints on base pairs [Dec. 2023]
    • restraints on Chemical probing data [Dec. 2023]
    • exclude Watson-Crick edge for base pairing [Dec. 2023]
  2. Advanced control over simulation parameters: A new way of defining restraints that can help model alternative RNA structures and increased control over simulation parameters, enabling the simulations of conformational space searching, folding, and unfolding. [Dec. 2023]
  3. Enhanced data processing and analysis: Improved data processing capabilities, with a wider array of options for clustering folding trajectories and generating representative models, and reanalyzing the same simulation multiple times using different parameters, facilitating a more thorough exploration of RNA folding landscapes [Dec. 2023].
