Vfold Pipeline offers a new user-friendly approach to the fully automated prediction of RNA 3D structures with given sequences. It first predicts 2D structures using the Vfold2D model [1-6] and then predicts 3D structures based on the predicted 2D structures using the Vfold3D [7] and VfoldLA [8] models. The Vfold3D/VfoldLA methods are based on the assembly of A-form helices with loop and/or motif templates, extracted from the known RNA 3D structures.
Due to the limitation of the current template library, Vfold Pipeline may give no predictions.

The standalone version of the Vfold-Pipeline package can be downloaded via the following link.

In Example 1, the server first predicts 2D structures without H-type pseudoknot and then predicts 3D structures for tRNA 1ffy.
The final output page for example 1.

   Download example SHAPE file      View example SHAPE file in a new tab
In example 2, the server first predicts 2D structures including H-type pseudoknot given SHAPE restraints and then predicts 3D structures for RNA 1e95. Users should download the above example SHAPE file and then upload it using the upload button in item (6). Users can also just view the content of the example SHAPE file via the link above.
The final output page for example 2.


In example 3, the server predicts 3D structures for RNA 1e95 with the user given 2D structure.
The final output page for example 3.
