This section is being updated to reflect changes in the new NCBI website overhaul. Please bear with us.
If your publication is listed as "In process" with a yellow dot, then there is nothing you need to do at the moment. Your paper has been submitted through the NIHMS system, and is being deposited into PMC. Once a paper has been submitted to the NIHMS system, it generally takes 3-4 weeks for it to be deposited into PubMed Central and shift to the green Compliant dot. For grant renewal and reporting purposes, this is considered compliant.
However, it is highly recommended that you log in to the NIHMS system and track this publication periodically to ensure that no problems arise.
