How do I credit someone who made the trajectory file used for my thesis? There's a trajectory file which I included a sample of in my Appendix. Here's a screenshot:



Aside from stating in the Appendix text the name of the creator of the file, is there anything more I could do (like what they do for borrowed code: they insert the name of the creator in the code itself) ?
You could ask the original author to put the data in a data repository (like Zeonodo or Figshare) and claim a doi for it. That makes the data object citeable in its own respect and you can give credit in a persistent way (as a bonus you get the author to think about licensing of their data).
