No, you're quite correct. i.ifft ignores the actual input map, reading the data from the fftreal and fftimag files created by i.ifft. So you can't modify the i.fft output with e.g. r.mapcalc than use i.ifft on the result. The only modification which can be performed on the FFT data is masking; i.ifft reads the mask separately and applies it to the data. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
