I manually segmented the cells with IdentifyObjectMAnualls module and saved them as tiffs. And I need to use these as objects for the analysis of a time lapse sequence. But I am having trouble finding a (best) way to achieve that, i.e. use these segmented cells as objects. Intuitively I wanted to try ColorToGray or UnmixColors modules, but I get an error message saying the image isn’t color, but grayscale.
