Answer 1

fid = fopen('YourFile.txt', 'rt');
datacell = textscan(fid, '%s%*s%*s%*s%s', 'CollectOutput', true);
fclose(fid);
data_to_print = [{'ln Temp', 'Time'}; datacell{1}] .';  %transpose is important
fmt = '%8s%15s\n';
fid = fopen('NewFile.txt', 'wt');
fprintf(fid, fmt, data_to_print{:});
fclose(fid);
