Annotating two columns at the same time

Question

[Mozart]

Hello everyone. I have two columns containing ensemble peptide ids. I was wondering whether it would be possible to annotate, with just one command line, two columns at the same time.

the reason I ask for this is because the only idea I have in mind is to run 2 merge function one right after the other – not sure this is the best thing to do?

thanks in advance

what do you mean with annotate ?

[Mozart]

apologies for not making this clear. I have peptide ids and want to convert these into protein names.

Can you include some example data, and an example of what you want the output to look like?

[Dunois]

Could you please illustrate what you'd like to do with some example data (and the expected output)?

Thanks for the comments. I have a list of ids interacting somehow with another list of ids. I want to convert these two lists into gene names.

Mozart : Not sure why you need it done at the same time. To remove redundancy perhaps? If you have your lists then convert them and reconcile later.

Thanks a lot – this clears things up.
