• Synapse identification and annotation
• Vesicle tracing
• Segment proofreading
• Quality assurance reviews

2. Review task description and requirements before starting
3. Confirm you have access to all required datasets
4. Note any special instructions or priority flags

2. Task Execution

1. Open the task in WebKnossos with correct viewport settings
2. Follow the specific annotation protocol for the task type:
   • Synapses: See GT Checklist (SOP-003)
   • Verification: See GT Verification (SOP-002)
3. Save work frequently (Ctrl+S)
4. Document any ambiguous cases or questions in task notes

3. Quality Check

1. Complete the pre-submission checklist before marking task complete
2. Review all annotations for completeness
3. Verify naming conventions are followed
4. Check for any missed structures in assigned volume

2. Add summary notes describing work completed
3. Flag any issues requiring reviewer attention
4. Notify team lead if task required significant deviations from protocol
