Hi all,
This is the binary image that I'm using to create the selections/ROIs. Kind regards, Jacqui -----Original Message----- From: Jacqueline Ross Sent: Friday, 18 May 2018 6:36 p.m. To: '[hidden email]' <[hidden email]> Subject: RE: Help wanted with time-lapse analysis - redirect to using stacks Hi Kees and Esteban (and anyone else trying to solve this!), I've now tried using a macro written by Jeffrey Murphy. It relies on having two folders of images. So, I've put the binary mask images in Folder A and the raw images for the other channel in Folder B. I still get different results when using the macro compared to manual measurements. It must be something simple but I can't work it out. I have attached two images, hope they aren't too big to get through. Here is my macro so far; // Jeffrey N. Murphy // @MurphysLab // 2015-06-30 // This presumes that the images in Folder A and in Folder B are in the same order! // Get a list of images in Folder A image_directory_A = getDirectory("Choose Folder A"); file_list_A = getFileList(image_directory_A); image_list_A = newArray(0); image_count_A = 0; for(i=0; i<file_list_A.length; i++){ if(endsWith(toLowerCase(file_list_A[i]),"tif")||endsWith(toLowerCase(file_list_A[i]),"png")){ image_count_A++; image_list_A = Array.concat(image_list_A,file_list_A[i]); } } // Get a list of images in Folder B image_directory_B = getDirectory("Choose Folder B"); file_list_B = getFileList(image_directory_B); image_list_B = newArray(0); image_count_B = 0; for(i=0; i<file_list_B.length; i++){ if(endsWith(toLowerCase(file_list_B[i]),"tif")||endsWith(toLowerCase(file_list_B[i]),"png")){ image_count_B++; image_list_B = Array.concat(image_list_B,file_list_B[i]); } } if(image_count_B == image_count_A){ for(img_i=0; img_i<image_count_A; img_i++){ open(image_directory_A + image_list_A[img_i]); image_A = getImageID(); open(image_directory_B + image_list_B[img_i]); image_B = getImageID(); // IMAGE A selectImage(image_A); // do what you need to make your ROI //run("Threshold..."); setAutoThreshold("Moments dark"); run("Create Selection"); roiManager("Add"); close(); // IMAGE B selectImage(image_B); // measure what you need using the ROI roiManager("Show All"); //run("Threshold..."); setAutoThreshold("Moments dark"); run("Set Measurements...", "area mean standard modal min integrated median skewness kurtosis area_fraction limit display redirect=None decimal=4"); roiManager("Select", 0); roiManager("Measure"); roiManager("Delete"); close(); } } Kind regards, Jacqui -----Original Message----- From: Jacqueline Ross Sent: Friday, 18 May 2018 6:31 p.m. To: [hidden email] Subject: RE: Help wanted with time-lapse analysis - redirect to using stacks Hi Esteban, Thanks for your reply. I tried your suggestion but can't seem to get it to work. The thing that troubles me is that I am able to get results using the Measure Stack macro but they don't match the results I get when I do the analysis manually.

Esteban Fernandez Sent: Wednesday, 16 May 2018 10:44 a.m. To: [hidden email] Subject: Re: Help wanted with time-lapse analysis - redirect to using stacks Jacqui, Your approach works for me with the "Confocal Series" sample image but only if I check the "limit to threshold" box in Set Measurements and leave the red Threshold overlay activated on the binary stack. The macro does scroll through the series. I wonder if with your dataset you have to use "Stack.setFrame(n)" in your macro instead of "setSlice(n)", since it is a timelapse not a z-stack. -Esteban On Tue, May 15, 2018 at 3:18 PM, Jacqueline Ross <[hidden email]> wrote: > Dear Kees, > > Thank you very much for that suggestion.

Select one of your split channel images and in the ROI Manager hit 'Measure' and the results table should pop-up with the measurements.

I've created a mask representing the overlap between the two markers using the Image Calculator so now have a binary stack to match the channel I want to measure. I want to measure gray values, area, integrated density, etc. defined by a threshold but only within the area where the two markers are collocated. > > However, when I try to do the measurements using the Redirect to: option and the Measure Stack macro, it seems like only the first image of the binary stack is used, not each corresponding slice. > > The problem I have is that there is movement of the labels between the time-points so I can't use a static ROI. > > I feel like this shouldn't be difficult but I can't get it working.
