Hi Lisbeth,
I still disagree for a database and explained why. Sidse confirmed that she gets my point.
Training students in finding out tissues is one thing - I do this with exercises - documenting practical work is another thing.
I'm fine if you want to lead students to only pinpoint and mention one tissue each study - but when there are several involved which cause and influence each other this is important to notice - see my example above. 

I wrote documentation must make sense, and it's a great opportunity to learn for both students and us all, when we have room to investigate constellations, interactions etc. It is a potential not a must, but frankly I don't work otherwise. 
Would you or Rob post the non-linear analysis here so I can see how it matches my own style, and whether it makes sense to have different categories of case studies?

What do you think about collecting quality cases from the professionals to keep their status active?
