Hi,
Firstly, apologies if there is already a thread for this, but I couldn't find one. In my experiments I am measuring intracellular fluorescence of an ion-sensitive dye in response to stimulation by an agonist. These experiments are over a 10 minute time course with an image acquired every second (600 frames in total). I have used multi measure to assess the change in fluorescence and this works quite well on the whole (thank you ImageJ!!). However, my cells are non-adherent and during the course of the experiment some cells start to drift (slowly). This causes problems as some ROI's are no longer placed appropriately by the end of the of the experiment. Is there a way to get ImageJ to reposition the ROI for each frame? Many thanks, Kirk |
Hi Kirk,
I don't have a good answer for you, just throwing my hat in because I've just been dealing with a very similar issue and would be interested to hear what's out there. Because I had to get this done and couldn't wait for a better solution to come up, I ended up doing the following: 1. Under Analyze - Set Measurements, I selected the measurements I was interested in. 2. Under Analyze - Tools, I opened ROI Manager. 3. In each frame, I selected my ROI (in my case, a T cell I was tracking in the brightfield channel to look for fluorescence appearing in the GFP channel), making sure I had my channel of interest selected, and after selecting each ROI I hit "t" to add the ROI to the ROI manager, and advanced to the next timepoint. 4. After saving each ROI in each frame, I saved my set of ROIs within ROI Manager, and then hit Measure under ROI Manager, which spit out a nice table of my results. Extremely time consuming, and after the 1500th ROI, rather mind-bending, but I got my data.

Hi Kirk,
Depending on the images you have you might be able to use something like the Image Stabilizer plugin (http://www.kangli.org/code/Image_Stabilizer.html) instead of changing the ROI.

Hi Kirk,
Realised that the Image Stabilizer plugin might not be the best option for slow drift correction. Some other options are: StackReg + TurboReg: Register Virtual Stack Slices Linear Stack Alignment with SIFT Elastic Alignment and Montage BIJplugin (http://bij.isi.uu.nl/) allows ROI to align large images Best wishes Kees -----Original Message----- From: ImageJ Interest Group [mailto:[hidden email]] On Behalf Of Straatman, Kees (Dr.) Sent: 22 October 2015 16:28 To: [hidden email] Subject: Re: Multi measure with moving ROI Hi Kirk, Depending on the images you have you might be able to use something like the Image Stabilizer plugin (http://www.kangli.org/code/Image_Stabilizer.html) instead of changing the ROI.

Thank you for the suggestions, I will give these a go and see if they solve the problem. I did try this a couple of years ago with some fewer frames and manually changed the ROI (similar to Mel's suggestion), however this does take a lot of time.
Best wishes, Kirk |
Greetings,
I have dealt with this very same problem, and the workaround I used was to consider the time-series as a third space dimension, then use the 3D object finder (I think it was) to locate column-like ROI's, then evaluated these ROI's at all time points. This requires the ROIs not to intersect, which may or may not be possible, depending on your data. I can provide more info if you need it.
