VIA webinar: Explore, annotate and analyse multidimensional images with Napari
This webinar, by Juan Nunez-Iglesias from the Monash eResearch Centre, will describe some of the capabilities of Napari, with a focus on 2D and 3D annotation and analysis. Hosted by Volume Imaging Australia, a special interest group of the Australian Microscopy and Microanalysis Society, and Microscopy Australia.
Napari is a Python library and application to explore, annotate, and analyse multidimensional image data. napari provides a fast 2D or 3D canvas, powered by OpenGL, and sliders to explore additional dimensions in your dataset. The canvas provides layers to overlay both images and derived data (such as segmentations, point detections, vector fields, and more). The user interface gives provides tools to control visualisation parameters and add annotations overlaid on your data, which can then be used for downstream analysis. A plugin ecosystem has developed around the project, providing sophisticated analysis tools.
Bio: Juan Nunez-Iglesias is a Senior Research Fellow at the Monash eResearch Centre. Juan has been working on image analysis tools and techniques since 2009. After attending the SciPy 2012 conference, he became an active collaborator in the Scientific Python ecosystem, joined the team for the scikit-image analysis library, co-authored the book Elegant SciPy (published by O’Reilly), taught at numerous Scientific Python summer schools, and created widely-used libraries such as skan (skeleton analysis) and napari. Since 2018, he has been supported by a Chan Zuckerberg Imaging Software Fellowship to continue to develop the image analysis software ecosystem in Python.

How to cut a 100mm silicon disk into small pieces (>10mm)?
thanks
During importing a file you are taken (@ 5.21 mins) as .txm files. How to create this .txm files for images?
Hi Parameswaren, thanks for your question. The .txm file is a proprietary file format created by the Zeiss microCT system. Avizo has the ability to import this file format. You cannot create this file unless you have the instrument. However, Avizo will allow you to import and export data in a range of other open source formats (such as TIFF or DICOM). You can just select this from the drop down list in the save function. Hope that helps.
it should be double or 70%
Easy and Interesting
hi, i want to know, what should I do if my sample cannot stick to double side adhesive ? I tried other tape, the sample still not attached…
In general, we tend not to use adhesives to mount nanomaterials for SEM examination. As you can see in the video, we usually create a well-dispersed suspension of particles and deposit a drop of that suspension onto a clean, featureless (preferably conductive) substrate such as a silicon wafer. Once the suspension liquid fully evaporates, we then image the remaining nanoparticulate residue in the SEM.
Thank you so much. Really nice presentation
Thank you!
Hi there, I want to analyze the permeability and tortuosity of a porous structure. Could you please provide me with any help or tutorial? Thanks
Hi, good question. The answer however is complex. Avizo has tools for doing this (as do other software packages). Normally the process would be to undertake some pre-processing steps to prepare the data (filtering/denoising). Then you would need to move to pore identification (of which there are various methods). Tortuosity and permeability measures could then be applied to the result of the pore labels. I would suggest looking up some of the functionality for this in Avizo by visiting their TH-cam channel. They have some videos on the study of pore structures including connectivity.
The information here is a little out dated. The ice issue is only exists in LN2 detectors which can be barely seen on SEMs nowadays. Modern EDS has great improvement in terms of efficiency and low-kV X-ray detection. The data in the example is from 1998. The spectrum processing at that period is not a good as modern EDS software, especially on peak overlapping issue and background subtraction. It's good to see the comparison with WDS. Lots of people over relied on EDS thus ignored WDS. Thank you for the presentation.
I worked in a EDS company. This is by far the best presentation I've seen about EDS analysis. Most importantly, it's based on practical experience that you need to know or be aware of in the analysis. Also, it's not quite easy to put all the sessions into one hour talk. Good job and thank you for the presentation.
Thank you :)
Wow....I learnt alot
Glad it was helpful!
what on earth is this resin
How much amount needed to sent for a sem analysis test of nanoparticle
The amount of nanoparticulate material required cannot be precisely specified. We generally advise individuals to bring approximately ~1g of (dry) nanoparticles, and only use a fraction of this amount for SEM or TEM examination. If the nanoparticles are suspended in liquid, then a concentration that alters the visual properties of the liquid (i.e., makes it ‘cloudy’) should be sufficient. It is always recommended to consult the microscopy specialist(s) with whom you are working for their recommendation. Because engineered nanomaterials are considered hazardous substances, only minimal quantities should be handled, and storage and handling should be done in accordance with local and federal safety guidelines and regulations.
Thank you so much
You're most welcome
Amazing presentation! I got a lot of ideas from your presentation. It helps with how to deal with SEM images.Thank you very much.

wow
Is it necessary to dry the prepared nano particles prepared by wet chemical method?
Yes, samples need to be vacuum stable and should be fully dry before attempting to image them in a SEM. Even in an ESEM instrument, which can handle a certain degree of moisture, the SEM is only capable of imaging the surface of the sample, so will not be able to ‘see’ nanoparticles suspended inside a liquid.
This is by far the best demonstration video I have ever watched.
To find the appropriate spot size, aperture and all the other parameters seems not so easy. How do you find them? Are there some rules?
Very informative.👍
I am very thankful for your video. This is very informative and really helpful Thanks

Hi Navnath, can you explain where you are having trouble?
Hello! I have one problem with Avizo. I work with snake skulls and make 3D models of the whole skulls. Once, I didnt finish the whole skull, just made some layers of one bone and then closed Avizo (Save project as and then Auto Save). On the other day, I opened Avizo and in Volume-1. labels (where you have four screens - XY, XZ, YZ and 3D view) I had only that selected bone (colored bone) but on the black background where I didnt have the rest of the skull = other bones that should be visible in greyish colour on the background. I have tried to close Avizo and then open it again but the situation was the same, so I cannot selected other bones to obtain 3D model of the whole bone. Thank you for any advices! :)
Hi Simona, I'll check in with our Micro-CT team and see if they have a solution :)
Hi Simona, sounds like you only saved the binary label field (the coloured one) using the auto save project method you selected. Not sure what version of Avizo you are using, but when you save the project you should select the "pack and go" option in the "save as type" dropdown list before clicking save. The "greyish" coloured data is probably your original data. Just drag and drop (or other opening method) this back into Avizo and save it again. Personally, I avoid saving projects unless I have to these days. I prefer saving only the very necessary files separately. Otherwise, you can end up with a lot of unwanted data saved.
Thank you for this very nice and informative video...
Glad it was helpful :)
helped me a lot! Thank you!

hello excellent lesson and PDF is there any way i can try this out on the turtle head DICOM data? would love to play with that scan
is not needed to fix the sample before? Is the sample was already fixed, how can I fix nanoparticles?
Fixation is a term we use for the process of preserving the structure of biological samples from their in-vivo state so that the samples can be examined in as unaltered a state as possible. Biological samples containing nanoparticles should be fixed as appropriate for that specific tissue type. There are many types of fixation methods; it is important to review the literature and consult experts regarding the best approach for your specimen type. It can also be very helpful to experiment with a range of fixation methods with non-critical samples to determine the optimum method for your particular application.
