abstract = {The available sequence data of RNA molecules have greatly
increased in the past years. Unfortunately, while
computational power is still under exponential growth, the
computer prediction quality from sequence to final structure
is still inferior to labour-intensive experimental work.
Although a reliable end-to-end procedure has already been
developed for proteins since Alphafold2, while its successor
AlphaFold3 can also predict RNA, its confidence, in
particular for novel sequences and folds, still appears
limited. Another strategy entails two steps: (i) predicting
potential contacts in the form of a contact map from
evolutionary data; and (ii) simulating the molecule with a
physical force field while using the contact map as
restraint. However, the quality of the structure prediction
crucially depends on the quality of the contact map. Until
now, only the proportion of true positive contacts was
considered as a quality characteristic. We propose to also
include the distribution of these contacts, and have done so
in our recent studies. We observed that the clustering of
contacts, as is common for many artificial intelligence
algorithms, has a negative impact on prediction quality. In
contrast, a more distributed topology is beneficial. We have
applied these findings from computer experiments to current
algorithms and introduced a measure of distribution, the
Gaussian score.},
