====== Spike analysis keys ======
Reading in settings(keys) has a hierarchy in spike_analysis !
Higher Priority will always override lower priority.


.

^Priority ^Settings file  ^Info ^Location^
|1|ph_general_settings.m|default, makes sure keys are present|spike_analysis folder|
|2|ph_project_settings.m|default settings for your project|Settings/Project|
|3|ph_project_version_settings.m|small deviations for one version (f.e. different dataset)|Settings/Project/version|
|4|additional_settings.m|probably obsolete, was used to define each run|Settings/Project/version|

===== Data batching (keys.batching.) =====
^Key  ^Format ^Possible entries  ^Info^
|monkeys|cellstr|{'Flaffus', 'Linus', 'Curius', 'Tesla', 'Cornelius', 'Magnus', 'TDT_brain', 'Bacchus'}|monkeys involved|
|combine_monkeys|scalar|0/1|combine monkeys for population analysis|
|targets|cellstr|{'dPulv_r','dPulv_l'} --> {'dPulv'} combines hemispheres|target from sorted_neurons table|
|Subregions_separately|scalar|0/1|Split in subregions or not|
|Subregions|cell|struct('monkey',{''}, 'target',{''}, 'grid_x',{NaN}, 'grid_y',{NaN}, 'z_min',{NaN}, 'z_max',{NaN})|subregion definition by ranges|
|n_Subregions|scalar||numel(keys.batching.Subregions)|
