TITLE: NCBI submission protocol for microbial pathogen surveillance
AUTHORS: Candace Hope Bias, Julie Haendiges, Tina Lusk Pfefer, Errol Strain, Maria Balkey, Ruth Timme

[DESCRIPTION]

PURPOSE: This document provides detailed instructions on how to submit whole genome sequence (WGS) data and associated contextual data of microbial pathogens to NCBI for analysis within NCBI Pathogen Detection, while adhering to the INSDC standard data structure, "Pathogen DOM,". The protocol includes essential steps to create a new NCBI submission environment for your laboratory group, which is crucial to have in place before data are submitted. After these initial setups, the the remaining protocol focuses on step-by-step instructions for data submission.
 
SCOPE: This protocol is intended for any laboratory submitting WGS data of bacterial pathogens to NCBI for analysis within NCBI Pathogen Detection. This encompasses US labs connected to GenomeTrakr, NARMS, Vet-LIRN, NAHLN, and other international networks and submitters.

GUIDANCE FOR NEW SUBMITTERS: Before initiating your first data submission, there is significant preparatory work required. We advise designating a team member to spend several days setting up the necessary systems well before your anticipated first submission.

Watch NCBI's 10min video tutorial describing general submission to SRA.

ADVICE FOR FREQUENT/LARGE VOLUME SUBMISSIONS: Start by following Step 1 to establish your NCBI submission environment. For ongoing or large-scale submissions, email gb-admin@ncbi.nlm.nih.gov to arrange an account for API-based submissions.

[BEFORE_START]
This protocol has three sections:

Section 1: Setting up NCBI accounts (for new users)
Section 2: Data submission to BioSample for sample metadata and to SRA for raw reads and associated sequence metadata. 
Section 3: Detailed steps for creating a BioProject (usually done once during the account set-up)

[STEPS]
SECTION: Establish submission environmnet at NCBI
1. Set up a new NCBI submission environment for your lab:

1.1: Create an NCBI user account
1.2: Set up an NCBI submission user group for your lab
1.4: Bookmark the link to your submission portal
1.5. Identify or establish new BioProjects (detailed in Step 3)


Ready for data submission:
After these steps are complete you can proceed with data submission in Step 2.
SECTION: Establish submission environmnet at NCBI
1.1. Create an NCBI user account at NCBI: https://www.ncbi.nlm.nih.gov/account. This will be your own individual user account at NCBI.  

 

  Choose a signup option that works for your institution.
SECTION: Establish submission environmnet at NCBI
1.2. Establish an NCBI submission user group for your laboratory. 

We recommend using this user group for all NCBI submissions related to your labs's pathogen genome surveillance submissions. 

This approach will link data submitted by your lab to the user group and not to individuals doing the submissions, allowing anyone in the current submission group to perform updates or retractions and answer inquiries from the NCBI staff, even if there's been a complete turnover of staff since the original data were submitted. 

User groups also ensure consistent data ownership across BioProjects, BioSamples, and sequence data.  If your laboratory has non-overlapping research groups submitting and managing data at NCBI, multiple user groups can be established, if needed, to manage these efforts separately. 

Your laboratory might already have a submission group established!  Sign into your personal NCBI account, then check the "Group" tab in the Submission Portal (Submission Portal | NCBI | NLM | NIH).  Ask your colleagues to do the same to ensure your laboratory does not already have one in place.


 

Click on this link to verify your membership in NCBI user groups: https://submit.ncbi.nlm.nih.gov/groups/

Creating a new submission group: 

1. On your NCBI profile page (https://submit.ncbi.nlm.nih.gov/accounts/profile/), scroll to the bottom of the page and click on the "Create group for shared submissions" button. 
 


 

2. On the resulting page, fill in the required information to create, at minimum, a short name, full name, and contact information for this submission group.

 

3. To invite members, use either the "Invite members" button at the top of the next, "Members" tab or from the "Invites" tab itself to navigate to the invite tab and add the invitees' emails to the text box. Click the "Invite Members" button when finished.

 


SECTION: Establish submission environmnet at NCBI
1.3. Managing your NCBI submission user group.  

After a user group has been established it can be edited for membership and permissions by clicking in the “group” tab of the submission portal (https://submit.ncbi.nlm.nih.gov/groups/), then on the Group Id hyperlink, e.g "fda_ny" in the above example. 

Users with admin privileges can update contact information in the "Profile" tab and membership in the "Members" tab. New members can be invited by clicking on the "Invite members" link.  


 

This user list should be kept current as members/staff enter and leave the laboratory.   

Permissions levels:
READ: primarily for collaborators who would like to view the submissions, but not edit them.
MODIFY, SUBMIT, DELETE: Permissions to submit, modify, or retract data (members usually have all or none of these permissions)
ADMIN: Can invite or remove members of the submission group. Ensure that at least one (or more) members of your group have ADMIN privileges.

The "Submissions" tab will show a breakdown of how many submissions have been made by this group: 

 

SECTION: Establish submission environmnet at NCBI
1.4. Bookmark “My submissions” at NCBI: https://submit.ncbi.nlm.nih.gov/subs/. This is the page where you view and track current and past submissions. 

 

SECTION: Establish submission environmnet at NCBI
1.5. Identify or establish new BioProjects (Umbrella and/or Data BioProjects)

Umbrella BioProjects. If you are already part of a surveillance network, (e.g. GenomeTrakr, NARMS, Vet-LIRN, NAHLN, PulseNet, or others), you should follow the guidance from each network coordinator for creating new BioProjects.   

For GenomeTrakr: create a new data project and link to one of the established umbrella BioProjects. For reference, here is a list of the major Umbrella projects for GenomeTrakr, organized by taxonomic classification, PRJNA593772. For species not included in this list, create a general, non-targeted data BioProject and link it to PRJNA706684, our multi-species BioProject.

GenomeTrakr Umbrella projects ():
Campylobacter sp.		        PRJNA258021 
Cronobacter sp.                             PRJNA258402
Escherichia coli / Shigella             PRJNA230919 
Listeria sp.                        		PRJNA514048
Salmonella sp.            			PRJNA183844 
Vibrio sp.                        		PRJNA245885
All other species                            PRJNA706684

If you need to establish a new umbrella BioProject, follow instructions in Step 3 with modifications for creating a new Umbrella BioProject (Step 3.12).

Develop an internal method for storing and tracking your BioSample and SRR accessions! They are required for making future updates to your records.

For updates, corrections, or retractions to your BioSample and SRA records, follow the guidance provided in the NCBI Curation Protocol. Some edits can be made within the submission portal and others need to be done via email. 
 


 

SECTION: BioProject Creation
3. Create a new BioProject  

BioProjects are an organizing tool at NCBI that pulls together different kinds of data submitted across multiple NCBI databases. Each BioProject has a unique URL, providing a home page with a title, description, links to lab websites, publications, and funding resources associated with a particular project, along with links to the deposited data. A basic data BioProject holds actual sequence data, assemblies, and their associated metadata. An umbrella BioProject is a way to group two or more data BioProjects together, which is useful for coordinating disease surveillance and for looking across the grouped BioProjects in a single view.

This portion of the protocol describes the steps for creating a new data BioProject linked to an existing umbrella BioProject (usually established by a coordinating group, e.g. GenomeTrakr, NARMS, Vet-LIRN). 


*If you need to create a new Umbrella BioProject, modifications are summarized in Step 3.12.
