+PlotID/removePltIdFiles.m

 function [fListClean] = removePltIdFiles(fList)
 %removePltIdFiles removes functions that are part of PlotID out of flist
 %   Detailed explanation goes here
-%addpath('..\fcn_core');
 
 [~,names,ext] = fileparts(fList);
 names = strcat(names, ext); % add ext for comparison
 
 % Get a list of all .m files that are part of Plot id
-PltID_flist = struct2table(dir('+PlotID')); %get list of files 
-[~,~,PltID_flist.ext(:)] = fileparts(PltID_flist.name(:)); % add ext column
-
-PltID_flist = PltID_flist(strcmp(PltID_flist.ext,'.m'),:);
+packageContent = what('PlotID');
+PltID_flist = packageContent.m; %get list of files 
 
 % Comparison and filter
-fListClean = fList(~ismember(names,PltID_flist.name));
-
+fListClean = fList(~ismember(names,PltID_flist));
