#Software Platform #IT and Bioinformatics

  • Non-coding RNA
  • Secondary structure prediction
  • MicroRNA prediction
  • Large-scale research
  • piRNA prediction

Field of activity

– Prediction of non-coding RNA secondary structures.
– Large-scale identification and prediction of non-coding RNA genomic sequences, particularly small RNAs (microRNA, piRNA, etc.).

ÉvryRNA is a web server that provides the scientific community with access to the range of non-coding RNA predictive tools and algorithms developed by Ibisc :

  • Algorithms for the prediction of RNA secondary structures, including pseudoknots: P-DCFold (Tahi et al., IJAIT 2005), SSCA (Engelen and Tahi, BMC Bioinformatics 2007) and Tfold (Engelen and Tahi, NAR 2010),
  • Algorithms for ab initio prediction of microRNAs: miRNAFold (Tempel and Tahi, NAR 2012), miBoostSVM (Tran et al., RNA 2015) and ncRNAclassifier (Tempel et al., BMC Bioinformatics 2012),
  • Algorithms for the prediction of piwi-interacting RNAs (piRNA): piRPred (Brayet et al., Bioinformatics 2014).


  • P-DCFold, for the prediction of RNA secondary structures, including pseudoknots.
  • SSCA, for the selection of homologous sequences in a comparative approach to predicting RNA secondary structures.
  • Tfold, for the prediction of secondary structures, including pseudoknots (integration of SSCA and P-DCFold).
  • miRNAFold, for ab initio large-scale research of microRNA precursors (pre-miRNAs) in genomes.
  • ncRNAclassifier, to determine if a non-coding RNA is derived from a transposable element (TE) or confused with a TE.
  • miRBoost, to identify true or false pre-miRNA sequences.
  • piRPred : for piRNA prediction.
  • IpiRId: software for integrative piRNA prediction.

Complementary tools

  • RNA-SC: for the comparison of predicted RNA secondary structures to reference structures.
