Actin Fiber Analysis using DiameterJ

Tags: #<Tag:0x00007fd54300d550>


Hi, I am trying to use Diameter J to analyze actin fibril diameters in fluorescent microscopy. I have tried image types .gif .tif and .jpeg and get error messages every time. I can’t get the image segmented, and am wondering if I have the wrong format? I do not have access to raw images as I am analyzing data collected last year, and used photoshop to convert to RGB color. I am new to this program and hope someone can help! Thank you :slight_smile:



Welcome to the Forum and ImageJ in general.

I haven’t used DiameterJ much myself… so perhaps others here have better insight on that particular plugin - but we can at least get the ball rolling…

What are the types of images you are working with? You mentioned .gif, .tif, and .jpeg (warning: DO NOT USE JPEG for quantification analyses… this is why) - so are you converting the original images each time? Would you be able to attach the most raw/original image files you have? At least one for an example for us to test.

You can convert images to RGB in ImageJ (whatever processing you do to your images - keep it all in ImageJ if you can - to keep it more reproducible, etc) - you can search the ImageJ User Guide. Here are a few other helpful links for getting started with ImageJ/Fiji:

Hope this helps!



This is one of the images, it is the most raw version I have access to. What I have been doing so far is downloading this type of image, then converting to RGB color and then trying to put it back into the DiameterJ program. I am open to any suggestions to analyze my images or on the process I’ve been using.
Thank you very much for your help,



I think @DiameterJ will be the best person to help you with your analysis using this plugin.
