thank you, you are right. It is much more simple and faster than mine.

Again, thank you very much.

 

best regards,

you could do the same just with an octave script

----------8<--------------
#!/path/to/octave ##so that you can run the script from bash

year=2009
for month=1:12
 for day=1:31
   for hour=0:23
     min=0; sec=0;
     dir=<...>;
     filename=sprintf("%s/data-1day-1Hz/fft-%d%2.2d.dat", dir, year, month);
     fid=fopen(filename,"r"); # or:
                              # load (filename);

     ## other octave commands

     plot (...)
     print (...) ## to save the plot to a file

     fclose (fid)
   endfor

endfor

this should be __MUCH__ faster as it would not fire up many
different instances of octave and gnuplot.
