Preprint servers for statistical bioinformatics

14 February 2009

The COBRA Preprint Series was selected for the dissemination of the Statomics Lab’s working papers because it offers more flexibility than the other main services for statistical genomics preprints:

  • Unlike arXiv, COBRA accepts PDF files generated by LaTeX. Preparing LaTeX source code specifically for a preprint server can require large time investments.
  • Unlike Nature Precedings, COBRA does not require authors to irrevocably license their work for commercial reuse. Such licenses might conflict with the interests of some commercial publishers since they allow competitors to distribute the preprints for profit.
