create_study_fv.m

% create_study_fv() - creates a STUDY structure using ALL sets stored in a folder specified by the parameter "pathin".
%
% Usage: 
%             >> [STUDY, ALLEEG] = create_study_fv(pathin,pathout,studyname,badcomps);  
% Inputs:
%   pathin     - [string] path to the folder containing datasets
%   pathout    - [string] path where STUDY is going to be saved
%   studyname  - [string] name used to save STUDY
%   badcomps   - [0 1] badcomps=1 -> EEG.badcomps is created for each
%                single dataset as an empty field; badcomps=0 -> EEG.badcomps is not created 
%
% Outputs:
%   STUDY      - a new STUDY set containing ALL datasets stored in the folder 
%   ALLEEG     - a vector of EEG datasets included in the STUDY structure
