I have a network of protein - protein interactions, where the primary IDs of the nodes are Uniprot IDs. Now, some proteins can have different Uniprot IDs but share the same Gene Symbol, which I'm storing as an attribute in another column.
How can I merge nodes based on the value they have in the Gene Symbol attribute/column, while keeping all the edges of the original nodes?
I tried playing with Tools --> Merge --> Network but I can't get it to work (i.e.: nodes do not merge).
Any help is appreciated!
