i.ifft

[GRASS manager]

I'm getting an error message when trying to run i.iift.  It goes as follows:

ERROR: Unable to open file in the cell_misc directory.
       Input map probably wasn't created by i.fft

The inputs were generated from i.fft and there appears to be "fft-type" files
in the cell_misc directory.  Anyone know what the problem is and how to 
correct it?
