JPEG file of one fluorophore channel will have data in 2 or 3 RGB channels, so may need to delete unwanted RGB chanels (e.g. delete red channel from FITC JPEG, to leave only green channel.) Or, better still, convert fluorophore image to monochrome (i.e., so that luminance of flurophore channel is encoded as equivalent gray value from 0-255 in each RGB channel of the JPEG).
- Open JPEG files for each fluorophore/
- (e.g., FITC JPEG and TRITC JPEG)
- Using JPEG files, Drag and drop one channel from one JPEG file onto second channel in second JPEG file to create a merged JPEG file.
- e.g., drag green (FITC) channel on top of red (TRITC) channel
- Save merged image as JPEG file
