Rather work on fixed-field extraction method. I save a piece of your data in test.txt and here is how I read it back:

>> fid=fopen('test.txt','rt');
>> c=textscan(fid,'%s','Delimiter','\n')


c =

{6x1 cell}

>> fclose(fid);
>> s=char(c{1})


s =

Q (upper-edge --0.1250E-03 AmP )= 0.98880E-02+- 0.28300E-03 units/alpha/round
Q (upper-edge --0.2500E-03 AmP )= 0.19648E-01+- 0.39412E-03 units/alpha/round
Q (upper-edge --0.3750E-03 AmP )= 0.18384E-01+- 0.38318E-03 units/alpha/round
Q (upper-edge --0.5000E-03 AmP )= 0.17536E-01+- 0.37040E-03 units/alpha/round
Q (upper-edge --0.6250E-03 AmP )= 0.16064E-01+- 0.36000E-03 units/alpha/round
Q (upper-edge --0.7500E-03 AmP )= 0.15888E-01+- 0.35954E-03 units/alpha/round

>> firstcol = s(:,17:26)

firstcol =

0.1250E-03
0.2500E-03
0.3750E-03
0.5000E-03
0.6250E-03
0.7500E-03

>> data1 = str2num(firstcol)

data1 =

1.0e-03 *

0.1250
0.2500
0.3750
0.5000
0.6250
0.7500

% Do similar for other columns
% NOTE: textscan is NOT buggy when understand how it works
