need help with textscan order

i want to get some data from txt file so i used textscan order

saveFlnmCl = 'Save_Airfoil.txt'; 
fidAirfoil = fopen(saveFlnmCl); 
dataBuffer = textscan(fidAirfoil,'%f%f%f%f%f%f%f','Delimiter',' ','MultipleDelimsAsOne',true,'CollectOutput',1,'HeaderLines',3);

and here is my text file

XFOIL Version 6.99

Calculated polar for: NACA 2412

1 1 Reynolds number fixed Mach number fixed

xtrf = 1.000 (top) 1.000 (bottom)

Mach = 0.000 Re = 0.010 e 6 Ncrit = 9.000

alpha CL CD CDp CM Top_Xtr Bot_Xtr

------ -------- --------- --------- -------- -------- --------

4.000 0.1967 0.05553 0.03113 -0.0105 1.0000 1.0000

i want to read the values of alpha CL CD CDp CM Top_Xtr Bot_Xtr

so i write

al = dataBuffer{1}(:,1);
CL = dataBuffer{1}(:,2);    
CD = dataBuffer{1}(:,3);
CDp = dataBuffer{1}(:,4);
CM = dataBuffer{1}(:,5);
Top_Xtr = dataBuffer{1}(:,6);
Bot_Xtr = dataBuffer{1}(:,7);                                                                                                

but the answer appear as empty array as shown

i think the problem is from this line

dataBuffer = textscan(fidAirfoil,'%f%f%f%f%f%f%f','Delimiter',' ','MultipleDelimsAsOne',true,'CollectOutput',1,'HeaderLines',3);

any suggestions please

the text file is attached

You have at least 10 header lines (empty lines count). I would need to open the file in an editor to count the exact number.

[Walter Roberson]

13 header lines.

S = fileread(Save_Airfoil.txt); 
S = regexprep(S, '^.*---\s*$', '', 'lineanchors'); 
dataBuffer = cell2mat(textscan(S, '%f%f%f%f%f%f%f'));
