use this command line head0=textread(file,'%s'); sf=str2num(char(head0(strmatch('sfrq ',head0')+2))) The value for that is '1' but i want the value '499.4240618' in the line above

I would rathr skip the passage with head0 and go directly with textscan as I showed below.

I think you mean "the line below" not "the line above"

sw=str2num(char(head0(strmatch('sfrq ',head0')+12)));

[Rafael Freire]

Yes it´s really the line below. Sory and thank you

fid = fopen('C:\Users\Oleg\Desktop\test.txt');
out = textscan(fid,'%s%f%f%f%f%f%f%f%f%f%f\r\n%f%f\r\n%f','CollectOutput',1);
fid = fclose(fid);

out{2}
