|Model/VGG19|  |channel list| can be found here

to use channel list with VGG19
turn
guided dreaming ON
max classd and pyramid max OFF

other models (no channel list found yet)
max classd OR pyramid max ON
GUIDED DREAMING TURNED OFF

CHANNEL LIST
numbers for the individual directories of VGG19 are listed here 

AT LAYER
I'm guessing this is the same thing as the channel list, just for other models (not sure)

GUIDED DREAMING
if you want to have more control over dreamed features beyond the typical eyes and faces of dogs that you see all the time, you can set the guided dreaming parameter to ON in order to enable dreaming of specific classes.
You can select and mix an arbitrary number of VGG19 classes from this list by adding the corresponding indices to channel list.
an example of mix of numbers = [1] [50] [196]


MAX CLASSD
(not sure) 
Instead, if you want the algorithm to dynamically select the class to which the model assigns the highest probability, set max_output (maybe max classd) to ON

PYRAMID MAX
An experimental feature is the 
pyramid max parameter, when set to ON it selects the most probable class independently in each octave.

NO CLASS
no class doesn't seem to do anything interesting on vgg19 for now (maybe on other models)
