Thank you so much for your explanation Alicerita, this video is very helpful! Doing experiments is always great, but analyzing data could be tricky sometimes!
You're welcome 😊 You are right, executing an experiment can sometimes be straightforward. However, analysing and interpreting the result is another level of serious brain work.
Thank you Alicerita. How do I just count the objects joined together (clusters/clumps) and how do I distinguish the total numbers of single objects from the clumps? Also how do I graphically interpret this?
Hello Mam, thankyou for the video. I am trying this process on counting protoplast images from microscope and it's not working out for me. Can you please help out!
Hi Alicerita, I am currently having a big challenge counting senescence cells stained during galactosidase essay. This approach does not seem to solve my problem. please help out, Thanks.
Hi Alicerita! A big thank you for your video! Is it possible to create a batch analysis similarly to you video "Batch processing in Image J (…)"? I tried, but when I go into Process > Batch > measure, I can’t do an analysis. Do you have any idea how to do that? Thank you in advance!
Thank you very much for the Tutorial. Do you have any advice for automated quantification for IHC-stained muscle fibers? I have to count the positive fibers(not cells) and have been doing it manually. Thank you in advance!
Hi Anna, Thank you for your kind feedback. I have not attempted the counting of the filaments before. But you can record the macro for the manual processing you have been doing and then use the script to automate the analysis. Here is a link for how to automate your analysis th-cam.com/video/V2mO4MC0dho/w-d-xo.html
That is beyond my knowledge. A machine learning might be able to do that. But such requires more than 100 images to train the machine that A is metal, B is non metal AND c is fibre. That way, the trained machine can analyse the rest of the data.
Hi Alicerita, your tutorial video is so helpful. Thanks for sharing. May I ask one question? If my object's signal is faint, when I was using "Phansalkar Threshold", there was so much background noise. So it is very hard to do counting particles. By the way, I could not change the confocal setting as I need to treat every group with the same parameters. Do you know how to deal with this problem?
Hi @lang Jiaqing Thank you for your kind comment. You can improve the intensity by going to PROCESS | ENHANCE CONTRAST This will open a window to apply a % of pixel, just click okay and that should brighten your sample. It's best to apply the same % to all your samples to keep the result consistent
Thank you. Do you think two images taken at different dates can be compared to show which spots are new and where. I don't think image j can do this but have you ever spoken to developers to expand function such as this?
Hi Yo, I am not sure of how to do this. A time-lapse would have been best to detect which is new or old. There are plugins you can try, Napari plugins and others maybe able to do this.
Hello I have a question I want to count hair graft with imageJ ( i have numbers of grafts but when I use this app the results is not correct ) Would you please help me ?
@zahraahmadi2234 I looked at the image yesterday and felt discouraged from trying. There is almost no contrast between the red background and the grafts. So it might be inaccurate to count how many there are.
Hello, thank you for this wonderful tutorial am giving a task to count number a number of floor tiles from an image, i would like to show you the image. the counts result am having is not convincing and I tried few threshold and its just getting worse. so can you please advice me on how to carry on? thank you
Ma'am, thank you so much for this video. This is very helpful. I have a few questions since I'm a newbie in using Image J/ Fiji. 1. Do you recommend the same procedure for a confocal z-stack? Will making an MIP of the stack be a better option than counting it in 3-D? 2. What are the units of the values in the results? Are they in micrometres?
Hi Uzma Din, The MIP or 3D quantification depends on the type of samples you are working with. If you feel that you see more in 3D than in MIP, then choosing 3D would Abe the recommendation l. However, if the MIP gives a good representation of the 3D, then that's better. Before performing the analysis, image calibration is a good way of defining the output parameters. If ita a confocal .lif file, imageJ will automatically detect the image calibration and produce the result in micrometers
@@AliceritaE thank you for responding. My images are z stacks of 30 microns thick sections and I'm focusing on neurogenic ventricular zone. The brdu positive cells come in clusters. If i take an MIP, the clusters become a large blob in the 2-D. I believe 3-d cell counting is a better option for me. Do you have any video explanation of 3-d counting? That will be of great help. Good day to you!
Hello just watched your video thanks for the lecture. Am trying to count IHC puncta staining on a slide and I am getting off results. Will really appreciate your assistance.thanks
Hello Bhawna, I just finished testing one of the images you sent to me in email. It's difficult to accurately work out the measurements because 1. The bubbles are of different sizes. 2. Some of the bubbles are not in the perfect focus (therefore, masking the bubbles causes ring formation.). Therefore, I gave up on the measurements. I can try again layer at the weekend to see if there is a way to improve the image analysis better.
Thank you so much ma'am for looking into my images. I am truly grateful. If I may ask what do u mean by 'tmaome of the bubbles '? Also, if I used labelled material which forms such droplets, can this issue be resolved?
Thank you very much for the video! It helped a lot! Greetings from Brazil!

Thank you Andry, this comment made my day, thank you.
Dear Alicerita, nice tutorial thanks. Do you know how to determine the x y z coordinate for a z stack
Hello, I will check for it and make a new video if found.

Thank you Alicerita.
How do I just count the objects joined together (clusters/clumps) and how do I distinguish the total numbers of single objects from the clumps?
Also how do I graphically interpret this?
You're welcome Nelson.
Apply watershed, it will split the clumped objects into fragments
You can plot the total number of count in a sample to compare with a control. If you have different treatments.
Thank you ma'am it's really helpful. I have a question regarding the unit of area of individual cells. How can I set it to micrometers squared?
excellent video! thank you!!

Thank you so much for your video Alicerita,. How do you go about counting cells in a specific area pleaase
Hi Jaden, by using the ROI to crop that particular area before processing.
The ROI are the shape tool on the ImageJ window
Thank you 😊
You are welcome
This is one of the things I have to learn.

Hi
How can I export the results to shp format to work on them in QGIS? I'd appreciate the help
Hello, i do not know how to do that. I don't even know what QGIS is 😊
Can we differentiate the particle for classification like metal, nonmetal, and fiber?
is it possible?
That is beyond my knowledge. A machine learning might be able to do that. But such requires more than 100 images to train the machine that A is metal, B is non metal AND c is fibre.
That way, the trained machine can analyse the rest of the data.
Alternatively, if you can differentiate them by side, if the three particles have a specific size range.

Hi @lang Jiaqing

This will open a window to apply a % of pixel, just click okay and that should brighten your sample.
It's best to apply the same % to all your samples to keep the result consistent
Pls let me know if that works

Hello Bhawna, it may work if the bright field image displays some contrast.
