CoFold
A tool for prediction of RNA secondary structure that takes co-transcriptional folding into account

CoFold is a thermodynamics-based RNA secondary structure folding algorithm that takes co-transcriptional folding in account. This has been shown to significantly improve the state-of-art in terms of prediction accuracy, especially for long sequences greater than 1000 nt in length.
