Submissions received through the In Review service first undergo a quality check at the journal. Once the quality check is complete, Research Square will begin processing the manuscript for posting as a preprint. This can take up to 3 weeks to complete depending on the journal you submitted to.
If your manuscript is submitted at a Nature Portfolio journal, your preprint will be posted once it has been sent out for peer review.
It is possible to request that your preprint be posted sooner. Follow the procedure on our Can my preprint be posted in the next few days page.
