Biorxiv offers the possibility to transfer an article uploaded as a preprint to a peer-reviewed journal. An increasing number of journals are available for this transfer service.
I tried to find more information on how this transfer works but there's not much information on the Biorxiv website. Before I use this service I would like to have more details. For example, I would like to know when do we upload a cover letter or suggest reviewers. It seems that once the article is transferred it appears in the author's home page on the publisher side but how can this transfer be complete without filling the other information usually asked during submission?
Has anyone tried this service?
