RNApdbee--a webserver to derive secondary structures from pdb files of knotted and unknotted RNAs.In RNA structural biology and bioinformatics an access to correct RNA secondary structure and its proper representation is of crucial importance.  Here, we introduce RNApdbee-a new tool that allows to extract RNA secondary structure from the pdb file, and presents it in both textual and graphical form.  RNApdbee supports processing of knotted and unknotted structures of large RNAs, also within protein complexes.  RNApdbee is implemented as a publicly available webserver with an intuitive interface and can be freely accessed at http://rnapdbee.cs.put.poznan.pl/.
