I am having extreme difficulty working even the basics of Image Pro 10. I create ROI and use the 'Dark' option in the Count/Size menu, in the Segment sub-menu. Even if the data collector table opens, I cannot get any kind of data into it, regardless what kinds of measurements I have selected under the the Types drop-down menu in the Measurements sub-menu of the overall Count/Size menu. All I want is to have the general intensity information (mean, standard deviation, minimum and maximum), general ROI information (perimeter and area) and percent of area within the ROI that is selected via the 'Dark' option. I cannot find a way to get any of these. Additionally, I cannot find any kind of manual. Is there anything anyone can tell me regarding this issue?
