function perceive(files,subjectIDs,datafields)
% https://github.com/neuromodulation/perceive
% v0.1 Contributors Wolf-Julian Neumann, Tomas Sieger, Gerd Tinkhauser
% This is an open research tool that is not intended for clinical purposes.
%% INPUT
% files:
% All input is optional, you can specify files as cell or character array
% (e.g. files = 'Report_Json_Session_Report_20200115T123657.json')
% if files isn't specified or remains empty, it will automatically include
% all files in the current working directory
% if no files in the current working directory are found, a you can choose
% files via the MATLAB uigetdir window.
%
% subjectIDs:
% you can specify a subject ID for each file in case you want to follow an
% IRB approved naming scheme for file export
% (e.g. run
% perceive('Report_Json_Session_Report_20200115T123657.json','Charite_sub-001')
% if unspecified or left empy, the subjectID will be created from
% ImplantDate, first letter of disease type and target (e.g. sub-2020110DGpi)
%% OUTPUT
% The script generates BIDS inspired subject and session folders with the
% ieeg format specifier. All time series data are being exported as
% FieldTrip .mat files, as these require no additional dependencies for creation.
% You can reformat with FieldTrip and SPM to MNE
% python and other formats (e.g. using fieldtrip2fiff([fullname '.fif'],data))
%% Recording type output naming
% Each of the FieldTrip data files correspond to a specific aspect of the
% Recording session:
% LMTD = LFP Montage Time Domain - BrainSenseSurvey
% IS = Indefinite Streaming - BrainSenseStreaming
% CT = Calibration Testing - Calibration Tests
% BSL = BrainSense LFP (2 Hz power average + stimulation settings)
% BSTD = BrainSense Time Domain (250 Hz raw data corresponding to the BSL
% file)
%% TODO:
% ADD DEIDENTIFICATION OF COPIED JSON
% BUG FIX UTC?
% ADD BATTERY DRAIN
% ADD BSL data to BSTD ephys file
% ADD PATIENT SNAPSHOT EVENT READINGS
% IMPROVE CHRONIC DIAGNOSTIC READINGS
% ADD Lead DBS Integration for electrode location
