Genome Assembly Dataset Curation

This skill guides processing of genome assembly datasets for VEuPathDB resources.

Prerequisites Check

This workflow requires the following repositories in veupathdb-repos/:

• ApiCommonPresenters
• EbrcModelCommon

First, run the repository status check to verify repositories are present:

Note: this script is located in the skill directory

bash scripts/check-repos.sh ApiCommonPresenters EbrcModelCommon

If repositories are missing, the script will provide clone instructions.

Branch Confirmation: After verifying repositories exist, check their current branches and status using git -C <path>, then confirm with the user before proceeding. Users typically create dataset-specific branches (see curator branching guidelines).

Example:

git -C veupathdb-repos/ApiCommonPresenters branch --show-current
git -C veupathdb-repos/ApiCommonPresenters status -sb

Working Directory (Curation Workspace Directory)

IMPORTANT: All commands in this workflow must be run from your curation workspace directory (the directory that contains veupathdb-repos/ as a subdirectory).

For Claude Code:

• DO NOT use cd commands to change into veupathdb-repos/ subdirectories
• Use git -C <path> for git operations in subdirectories
• Use absolute paths or relative paths from the curation workspace directory
• Example: git -C veupathdb-repos/ApiCommonPresenters status instead of cd veupathdb-repos/ApiCommonPresenters && git status

The workflow will create a tmp/ subdirectory in the curation workspace directory for intermediate files.

Required Information

Gather the following before starting:

• VEuPathDB project - Valid projects listed in resources/valid-projects.json
• Assembly GenBank accession (e.g., GCA_000988875.2 including version)

Workflow Overview

Step 1: Fetch Assembly Metadata from NCBI

Fetch assembly metadata from NCBI using the GenBank accession.

Command:

curl -X GET "https://api.ncbi.nlm.nih.gov/datasets/v2/genome/accession/<ASSEMBLY_ACCESSION>/dataset_report" \
  -H "Accept: application/json" > tmp/<ASSEMBLY_ACCESSION>_dataset_report.json

Detailed instructions: Step 1 - Fetch NCBI Metadata

Step 2: Fetch BioProject Metadata

Extract the BioProject accession from the assembly report and fetch additional details.

Command:

node scripts/fetch-bioproject.js <BIOPROJECT_ACCESSION>

This retrieves the BioProject title and description, saved to tmp/<BIOPROJECT>_bioproject.json.

Detailed instructions: Step 2 - Fetch BioProject

Step 3: Fetch PubMed Data

Find and fetch publications for the genome assembly.

Command:

node scripts/fetch-pubmed.js <ASSEMBLY_ACCESSION>

Results saved to tmp/<ASSEMBLY_ACCESSION>_pubmed.json.

Detailed instructions: Step 3 - Fetch PubMed

Step 4: Curate Contacts

Identify and curate contact entries for the genome submission.

Contact identification priority:

1. Named submitter from assembly metadata
2. Senior/last author from PubMed publications (if available)
3. Curator judgment for additional contacts

Actions:

• Search existing contacts in veupathdb-repos/EbrcModelCommon/Model/lib/xml/datasetPresenters/contacts/allContacts.xml
• Create new contact entries if needed
• Present choices to curator for review

Detailed instructions: Step 4 - Curate Contacts

Step 5: Generate and Insert Presenter XML

Generate the datasetPresenter XML and insert it into the appropriate presenter file.

Command:

node scripts/generate-presenter-xml.js <ASSEMBLY_ACCESSION> <PROJECT> <PRIMARY_CONTACT_ID> [ADDITIONAL_CONTACT_IDS...]

Target file: veupathdb-repos/ApiCommonPresenters/Model/lib/xml/datasetPresenters/<PROJECT>.xml

Detailed instructions: Step 5 - Update Presenter Files

Next Steps

After completing this workflow:

1. Review generated XML for TODO fields that require curator input
2. Commit changes to dataset branch (curator handles git operations)
3. Create pull request for review (curator handles PR creation)

• scripts/fetch-bioproject.js - Fetches BioProject metadata from NCBI (esearch + esummary)
• scripts/fetch-pubmed.js - Fetches PubMed records linked to a BioProject (elink + esummary)
• scripts/generate-presenter-xml.js - Generates datasetPresenter XML from fetched metadata
• scripts/check-repos.sh - Validates veupathdb-repos/ repository setup (synced from shared/)
