Contributor communication SOP

Background

While wrangling a dataset from a contributor a wrangler needs to be in contact with the contributor in order to get the required metadata and data for a submission. This document provides guidance on how communication with contributors should be approached.

General guidelines

CC the wrangler-team email in all communications with contributors so that the team is aware of the current status and can pick up on communications if the primary wrangler is unavailable.

Record key communication events in the related github project tracker ticket by ticking the relevant box or making a comment if more detail is useful.

Keep emails clear, concise and to the point

Ensure the most important information is first - expect that the reader could lose interest at any moment

Make the subject line capture attention, including HCA/Human Cell Atlas is useful

Be gracious, polite and friendly

Always leave the option of a meeting to chat if things seem to be getting complicated

First contact

The aim of the first contact with a contributor is to find out some key information about the project and ask the contributor to provide more detailed information using the data questionnaire form(https://forms.gle/KFYna7zGdQvwya8b8) or by setting up a meeting in-person or via video chat.

The first contact email should contain:

  • Link to register as part of the HCA
  • Link to the dataset questionnaire(https://forms.gle/KFYna7zGdQvwya8b8) or an attempt to set up a meeting

Template email

Contact after an HCA publication email

Wrangler team might be CC’ed in an email informing the authors that a publication has been accepted as an HCA publication (subject HCA Branded Publication). In this case, we can contact them and do not wait for them to reach.

Template email- no preprint or publication available Template email- preprint or publication available

Follow-up contact

Once the primary wrangler has gained more information about the dataset, a custom spreadsheet can be generated with the relevant tabs and fields for the contributor’s experiment.

Before any data and metadata can be received, either the contributor or an authorised representative from their lab, must agree to the HCA terms and conditions by completing the HCA terms and conditions form.

The first follow up email should contain:

  • Link to terms and conditions form (https://forms.gle/8XW8vapGQJRfKrc36)

Template email

Once the terms and conditions form is complete, the metadata spreadsheet and the instructions and credentials for uploading data to their ingest upload area can be provided to the contributor.

The second follow-up email should contain:

  • Custom metadata spreadsheet
  • Link to metadata spreadsheet guide
  • Reminder that they will get the credentials sent to them shortly (Dev work)
  • Link to instructions for how to upload data to an upload area(https://github.com/ebi-ait/hca-documentation/wiki/How-to-upload-data-to-an-upload-area-using-hca-util)

If the contributors need help to edit an existing submission in ArrayExpress that was done by Enrique his Annotare credentials are stored in aws secrets.

Template email

Frequency of contact

After sending an email, we generally think one week is a reasonable time to respond. If a primary wrangler has not received any response or reason for delay they should send a reminder email after a week.

The reminder email should prompt the contributor to complete the step required to enable the wrangler to continue with their submission. It is nice to offer a call to talk over where the contributor may have been stuck.

If there is no response after a further week, the primary wrangler should send another prompting email.

If after two reminder emails have been sent without a response, the wrangler could consider:

  • CC’ing the PI or project manager of the contributor’s project
  • Bringing it to the attention of the Ingest Product Owner/Manager and asking for advice
  • For CZI funded projects - Jonah?

Confirming details, filling gaps

It is normal for some details to be missed by the contributor in the first instance.

There are some fields that aren’t strictly required but a wrangler should chase if possible:

For CBTM & HDBR donors

  • We have other means of accessing the full set of releasable metadata from these tissue banks so it is a good idea to check our sources to ensure we can include as much information as possible

For developmental donors

  • For embryos we ideally want carnegie stage, all HDBR samples should have this
  • Post-Conception weeks is a mandatory chase. Based on the survey we sent recently that was the most wanted field by the community.
  • genotype/karyotype information

For all experiments

  • Ethnicity
  • Age
  • Estimated number of cells
  • Library preparations: If more than 1 set of fastq files per library preparation, make sure the approach is properly displayed. Same library preparation was sequenced several times/produces more than 1 set of fastq files: Fill in the lane_index and communicate with contributors. Different library preparations come from one cell suspension: Make sure the library preps are separated properly with the proper process.process_core.process_id

It is also common for a wrangler to need to confirm ontology curations. It is possible that a new ontology term will need to be created if an appropriate term doesn’t exist

Only if there are supplementary files: Make sure the files have been input twice in the spreadsheet (In the proper tab and in the Supplementary files tab). Once the files are uploaded make sure that they are called exactly the same.

Final confirmation before submission

Once a submission is 100% valid and has been reviewed, a final confirmation email should be sent to the contributor with the latest spreadsheet attached to confirm they are happy with the curation.

Template email

Confirmation of Accessions

Once the submission has been successfully archived, accessions should be communicated back to the contributor. If there is a risk that the deadline the contributor gave will not be met, the contributor should be contacted to inform them of the risk and offer alternatives or workarounds. The project level accessions should be provided within the main body of the email.

By default, the release date will be set up to 2 years from the moment the submission is archived. This date can be changed to an earlier date (Provided by the contributor) but we won’t hold the data for more than 2 years

Once the dataset is released in an HCA snapshot release, the contributor should be informed and provided with the link to their dataset on the HCA Data Browser.

Follow-up email after release

Once the submission has been successfully released into the HCA data portal, it should be communicated to the contributors (Even if the dataset was wrangled from the public domain).

This is not only to increase engagement from the community, but also to encourage scientists to send us datasets that we may have not discovered and may be of interest to the HCA.

Template emails

These templates are considered a guide to provide a skeleton with the required information. The primary wrangler can choose to edit and customise to make it more personal or appropriate for the situation.

First contact - Data questionnaire

Dear [name/s of contributor/s],

Thank you for contacting us regarding your interest in registering your project with the Human Cell Atlas! Below you will find the first steps:

1 Register as part of the HCA by filling the following form: https://www.humancellatlas.org/register (if you haven’t already)

2 Please fill out the dataset questionnaire (https://forms.gle/HWADhk3Z6hUEbvVh8). The questionnaire asks for information about your experiments. This will help us create a tailor spreadsheet for you to fill out about your project.

Please be aware that as per GDPR guidelines, we are not able to directly wrangle any metadata or data originating from living donors. If your project contains metadata or data originating from living donors, please refrain from sending us that information.

After filling both forms, we will contact you with the next steps to continue the submission of your metadata collection and data.

I am happy to set up a meeting or call about any concerns or queries that your team might have.

Best regards,

[primary wrangler name]

If data is managed access

Dear <name/s of contributor/s>,

Thank you for registering with the HCA and filling in our Dataset Questionnaire.

Currently we cannot handle raw sequencing data for projects that require controlled access. However, we can help you get your processed data (Gene count matrices, annotation files, etc) and publicly available metadata into the DCP data portal.

Please confirm if that option is ok with you, and we will proceed to share with you the next steps in metadata assembly and data upload.

Best regards,

Contributor Matrices and Cell Types

Asking for Matrices from Contributor

Dear [name/s of contributor/s],

We are also working with CellxGene to wrangle projects with appropriate expression matrices. I was wondering if you would be interested in submitting your analysis files to the Cellxgene visualization portal?

We would require the following, and would create an h5ad object meeting Cellxgene’s schema requirements.

  • Raw count matrix
  • Cell type annotation
  • Cell-level metadata
  • Embedding (Tsne/umap/spatial coordinates)
  • Normalised count matrix (optional)

Please let us know and if you are able to provide the above files, we can work on submitting your project to the Cellxgene visualisation platform. Let us know if you have any questions!

Warm regards,

[primary wrangler name]

Informing Contributor of Project in HCA-DCP being wrangled to CellxGene

Dear [name/s of contributor/s],

I am writing about your paper [Name of Paper] which has been published in the HCA Data Portal. [Link to Paper in Data Portal]

We are now wrangling projects with appropriate expression matrices from the HCA DCP to CellxGene. I was wondering if you would be interested in submitting your analysis files to the Cellxgene visualization portal?

If so, we would need to alter the .h5ad file(s) accompanying the dataset to comply with Cellxgene’s schema requirements.

Let me know if you have any questions,

Warm regards,

[primary wrangler name]

On behalf of the HCA DCP

Informing Contributor of PRoject in HCA-DCP already wrangled to CellxGene

Dear [name/s of contributor/s],

I am writing about your paper [Name of Paper] which has been public in our HCA Data Portal. [Link to Paper in Data Portal]

As a pilot project, we have wrangled your dataset’s expression matrices to a private collection in the Cellxgene visualisation portal. To do this, we have altered your analysis file to comply with Cellxgene’s schema requirements.

This is the link to the private collection in CellxGene where you can download and explore the h5ad files. Please let us know in the next couple of weeks if there is anything you would like to change or update!

Warm regards,
