Hi,
I'm working on some genetics data. I have 6151 examples and 157 attributes. My attributes are patient IDs and my examples are gene names. My goal is to transpose the matrix table. Here is a sample of my data set:

My problem now is I can't use the "Transpose" operator because there are duplicate row/example names. In order to transpose it, the attribute name needs to be unique. I wish to find all the pairs that have the same example names and edit their names. I was thinking about doing a loop, but I don't really know where to start and what operators to use to change the row names. Can somebody give me some advises on how to achieve this?
Thank you!
