Erratum
Upon publication of the original article [1], on PubMed the author’s name “Victor M. Pulgar” was formatted incorrectly in the XML mark up and therefore appeared incorrectly on PubMed. In this XML mark up, the middle initial “M” was added as a Particle when it should have been included as a Given Name. The author’s name was incorrectly formatted in PubMed due to this error as “M Pulgar V” and not as “Pulgar VM”. The author’s name appears correctly on the BioMed Central website.
