Merge Pathways
The Merge Pathways feature allows you to combine two or more selected pathways into a single custom named pathway.

Use Case
If there are two or more selected pathways, you can click the Merge Pathways button and assign a custom name.

More Practical Use Cases:
- Multi-pathway studies: Merge Fatty Acid Biosynthesis and Fatty Acid Degradation into Lipid Metabolism.
- Subsystem simplification: Merge Glyoxylate Cycle and TCA Cycle into a broader Energy Metabolism.
- Custom grouping: Merge Nucleotide Biosynthesis and Amino Acid Biosynthesis into Biomolecule Biosynthesis for targeted analysis.
Undo Merge
- The Undo Merge option lets you revert pathways back to their original state.
Warning
If you made changes before merging, they will persist after the merge.
Warning
If you make changes after merging and then undo, those changes will be lost — you will return to the state at the time of merging.
Recommended
Make the decision to merge first and then proceed with the modifications.
