It would be much better if you uploaded a sample data file by clicking the paperclip button.
In lieu of that I created my own demo data file:
str = fileread('myfile.txt')
tkn = regexp(str,'EP(\s+\d+){3}(\s+[A-Z]\d+)+','tokens');
tkn = vertcat(tkn{:});
spl = regexp(tkn(:,2),'\w+','match');
uni = unique([spl{:}]);
drn = duration(sscanf([tkn{:,1}],'%u',[3,Inf]).')
fnh = @(t)contains(uni,t);
tmp = cellfun(fnh,spl,'uni',0);
tmp = vertcat(tmp{:});
tbl = array2timetable(tmp, 'RowTimes',drn, 'VariableNames',uni)
