Comments.Text: @llrs - True which is why I'm checking to see if there is any suitable slot that is used for this kind of extensibility. As in the example of `calc.params` where it is designed in such a way where it is ok to add items to that list

Title: Storing FindAllMarkers results in Seurat object
ThreadText: # Storing FindAllMarkers results in Seurat object
  
  (Asked by: username_0 on 2019-03-25)
  
  I am currently working on multiple datasets where each is managed by a separate `Seurat` object. For each I'd like to also compute the marker genes using the `FindAllMarkers` function. Where would it be a good practice to save the markers returned from the `FindAllMarkers` function? I tried adding an extra slot to the `Seurat` object with no success.
  
  I saw the `calc.params` slot and though I could add an item to that list. However, it doesn't seem like the right place as that slot is a list of the parameters used for the different functions executed on the data.
  
  Currently I have some wrapping object that has a slot for the `Seurat` object and a slot for the results from the `FindAllMarkers`. Is there any better place to put it? Somewhere within the `Seurat` object?

  You can stash anything you like in the `misc` slot (present in both v2 and v3 Seurat objects). I often use it for storing marker information to help with organization.
