spectral resampling in ENVI [message #55963]

Hi everybody,

When spectrally resampling an image from one floating point image
(300,1,484) (484 bands) to another floating point image having
dimensions (300,1,198) (198 bands) some of the values become NaN's
(i.e. floating point infinity). I found no record of this in the help
files nor in the forum so far.
I was thinking of replacing these values by averaging neighbors. But
I rather use something more robust to fix this (or otherwise see why
it happens). There is no division by 0. the wavelength range of the
smaller image (198 bands) is fully contained within the wavelength
range of the bigger image (484 bands).

Any ideas?

Cheers,
Tal
