Troubleshooting

Peak or event detection concepts support nanopore signal analysis. Source: Wikimedia Commons, CC BY-SA 4.0.

Troubleshooting is part of the Nanopore Wiki learning path. Troubleshooting nanopore work means connecting visible symptoms to pore state, sample quality, electronics, buffer chemistry, and analysis choices.

Core concepts

• Baseline drift often indicates temperature, electrode, membrane, surface, or flow problems.
• Sudden current jumps can indicate membrane rupture, pore changes, bubbles, or contamination.
• Decreasing event frequency may reflect depletion, clogging, adsorption, or pore inactivation.
• Analysis can reveal problems but should not be used to hide experimental instability.

Diagnostic workflow

Step	Description
1	Separate blank baseline, pore baseline, and sample recording phases.
2	Check noise, drift, and current level before interpreting events.
3	Compare sample traces with negative controls and repeat runs.
4	Document failed runs and suspected causes.

Typical applications

• Laboratory SOP improvement.
• Field sequencing reliability.
• Training and quality control.

Common pitfalls

• Changing multiple variables at once.
• Assuming every blockage is target binding.
• Discarding failed traces without learning from them.
