You must first deposit your preprint on a preprint server, such as bioRxiv or arXiv, to obtain a DOI.
Your preprint must not be published or under consideration for publication elsewhere.
You must be aware about the timing of the process. It can take up to:
- 20 days before a recommender decides to handle your preprint and therefore to send it out for peer-review.
- 50 days before a recommender takes a decision based on the first round of peer-review
- The evaluation of your preprint might take several rounds of review before the recommender take the final decision to reject or recommend your preprint.
Details about the evaluation & recommendation process can be found here
