filename = 'Atrain';
fid = fopen(filename, 'r');
all_data = {};
blocks = 0;
while true
for K = 1 : 4; L = fgetl(fid); if ~ischar(L); break; end; end
if feof(fid); break; end
nrow = sscanf(L, '# rows: %d');
blocks = blocks + 1;
all_data{blocks} = cell2mat(textscan(fid, '', nrow, 'headerlines', 1));
end
fclose(fid);
fprintf('File contained %d blocks of data\n', blocks);
