plone4bio is a set of products to do bioinformatics within our preferred CMS, Plone.

We are pleased to announce a new plone project: plone4bio. As the name suggest it is intended as a set of products to do bioinformatics within our preferred CMS, Plone.

What is plone4bio

The rationale of the plone4bio project is to provide an integrated environment where it is possible to manage and analyze sequences of proteome or genome.
The plone4bio package provides the possibility to add a new content type, called sequence, than can be either written by hand or imported from a FASTA file, and to apply to that sequence a program, called predictor, that gives a back a plot of predicted probabilities for the sequence to have a given property (the property that the predictor tries to determine).
A predictor can try to assess if a protein sequence is trans-membrane, whether a signal peptide exists, and so on.


The plone4bio.base is a package that defines a skeleton predictor: deriving from that it is possible to integrate any other application and visualize all the results together.


Is an example predictor, incapsulating the pscoils algorithm by Fariselli et al. available at
It is intended both as an example on how to integrate one's own predictor in the plone4bio framework.
