Hi I am trying to extract information from the getImageInfo() command.
How can I obtain, for instance the number of channels in an image. I am using the Deltavision Opener plugin, which opens all the images in a multicolour dataset as a single stack but the channel number is within the image info. If i getImageInfo() the channel number are displayed on the line "NumofWavelengthes: 3". How can i get this number '3' to put into the rest of the macro as a variable? I feel i'm missing something obvious, sorry!

Thanks
