Re: problem with the FFT/FPOWER

Dear Adriano,

I tried the below commands (18,19,24 & 25) on MIDAS-99NOVpl2.2, RedHat-6.2. Both
completed without any error messages. I also tried corresponding commands with
sizes 128x128 and 1024x1024, no apparent problems there either. Since I have no
idea what the commands do, I can't tell you whether the output is sensible or
not, but at least they APPEAR to complete normally.

Good luck.
