Chris,

Long time ago you helped by suggesting the program Iris for converting from
..jpg to spectrograms.

One of the instructions was to convert the color spectrum to a 8-bit/channel
black and white .jpg and use the slice tool.

It never occurred to me during all this time, but today I tried the slice
tool on the original colored .jpg's and it works fine also. The results look
almost identical as if I used the slice tool on the black and white .jpg.

Is the conversion color .jpg- b&w .jpg really necessary?

Thanks much,
