I work and teach in a field where public data is scarce (anatomical MRI processing). I planned to organize a few practical works for students this semester. I had a pretty hard time gathering publicly available data from different software suites/open projects to organize a consistent and motivating practical work. Now, my question is the following:
Given that all these data are available to download on the author/lab website, do I "have the right" to create "my own data set" from parts of this data and under what conditions?
The reason that pushes me to do so is that some of the data comes from different heavy archives with hundreds of unnecessary things, with heterogeneous naming from one source to another, and I would like to "repackage" only the needed data in a consistent and comprehensive way and make this repackaged archive available somewhere for my students.
