Here is an efficient solution using textscan. The test file is attached (you did not provide us with a sample file).
opt = {'Delimiter',' +*:','MultipleDelimsAsOne',true,'CollectOutput',true};
fmt = ['%*d%*d%*s%*d%*s',repmat('%f',1,6)];
[fid,msg] = fopen('test.txt','rt');
assert(fid>=3,msg)
C = textscan(fid,fmt,opt{:});
fclose(fid);
Which imports that last six columns of numeric data:
>> C{1}
