entry_type question

[Islast]

I've been confused about entry_type in the database schema: The wiki says the following about entry_type:

entry_type corresponds to a particular table in the mindcontrol app. If you want a table that shows freesurfer output and another that shows the resting-state fMRI default mode network (and their associated metrics), you would have two separate documents, one with {entry_type: "freesurfer"} and another with {entry_type: "rsfmri"}

In the example config file the entry_types are MT-on_PD, MT-off_PD, T1w, T2w and FLAIR.
It's unclear to me from these whether entry_type is specifying outputs or inputs of mindcontrol

entry_type specifies the inputs, both raw images and derivatives can be inputs to mindcontrol
