Exception while trying to use Coloc2

[zeitgeist1]

Hi,

Could anybody please help me solve this exception. I am trying to use this in two images with one red channel and another green channel image. I have set both the image type to be RGB colour. I have updated my installation of the software. But still, I get the below error. I am sure there is a simple solution but I am not sure I understand this exception.

Thanks a lot

You should not use RGB color images to measure colocalization. Try providing each channel as 8-bit or 16-bit image. (Instead of throwing an exception, the plugin should be improved to warn users when supplying RGB inputs.)

@etarena This is where I suggest adding the check to guard against RGB images.

Done. :)
