Hi,

The current ‘Image Analysis -> Measure ROIs’ function outputs the mean and SD cone catch values of the ROI. Is there a simple way to extract the values of each pixel within the ROI?

Thanks,

Pierre-Paul

Hi,

The ‘measure ROI’ function is set, specifically providing these summary metrics. It uses the basic ROI analysis functions in ImageJ (https://imagej.nih.gov/ij/docs/menus/analyze.html). If you go down to the section ‘Tools menu’ –> ‘save XY coordinates’ it seems to suggest a way to save all XY coordinates of each pixel together with their pixel value.

Cheers,

Cedric
