One of the curses of developing bioinformatics software is the long-term sustainability of the code. Inevitably some tools reach dead ends and are abandoned. This can happen for several reason, notably lack of funding and hardware failures.
One such example is our primers4clades, which used to live at http://floresta.eead.csic.es/primers4clades and http://maya.ccg.unam.mx/primers4clades, but is not available as a Web server anymore. However, Pablo Vinuesa and me thought it would be great to still provide it as a legacy tool and eventually packaged it as a Docker image, which is freely
available at https://hub.docker.com/r/csicunam/primers4clades . This is easy to run, as explained below, and avoids installing the pipeline locally, which is challenging due to a number of dependencies which are no longer easy to find (read more at https://github.com/eead-csic-compbio/primers4clades).
1) Docker installation
You can find instructions for installing the Docker (Server) engine
on Linux at https://docs.docker.com/engine/install/#server .
On Windows, our recommended procedure is to i)
install the Windows Subsystem for Linux (WSL) and then ii) the Docker
engine:
Please let us know if you manage to run the examples below with
Docker
Desktop for MacOS.
2) Running primers4clades on Docker
The following command-line examples show how to run primers4clades using Docker with an input FASTA file named 'bla1.fna' containing nucleotide CDS sequences. You can check the format required here:
