James and I were travelling by train to Geneva. We were to participate in the prestigious International Congress on Espionage & Sabotage. Time on a train is ideal for leafing through conference materials. Suddenly, I noticed that James was studying a figure that looked quite familiar to me. ``I didn’t know you dealt with spectroscopy. I see, this is a Strontium L_3 edge...''
The full version of STEMCor DigitalMicrograph plugin is now available for free download open-source. This incorporates all advanced options that were previously available on paid-basis only. The package includes the script-compiled gtk module as well as open-source codes. Thus, you can install it in your DigitalMicrograph...
After knocking on Bond’s door and receiving a slurred permission, I entered and froze on the doorstep. James was deeply absorbed in reading a few pages when I realized, with a jolt, that they were my own stories about him. “Ah, that’s you, Mr. Conan-Doyle-Malevich?” he said. “Come in, come in! I am just reviewing your opuses.”...
When I visited James Bond next time, I found him buried in a thick book filled with technical drawings and endless specification lists. “Aha, the annual intelligence-service review for all of Europe has already arrived?” I asked. “No,” he sighed. “This is the manual for an electric toothbrush I bought yesterday...
We updated the STEMCor tool with new functionality. In particular, a smooth package treatment of STEM series is now available. In parallel, an open-source DigitalMicrograph script is published, making acquisition and saving of such series easy. Several bugs have been fixed and further development is planned…
We’ve finally equipped Spectrum Imager with a hierarchical help system! The help opens in your default browser, allowing you to quickly navigate to the topics you need. Several bugs have been fixed, and import/export capabilities now support the EDAX APEX spectrum-imaging format. Download the latest versions at /msa/.
I had been thinking a lot about the topic James and I had strongly disagreed on last time. Although I hadn’t changed my mind, James’s position had become clearer to me. When we met again, I admitted that models can, at times, unnoticedly fill in gaps in our perception of the surrounding world. “But it doesn’t…”
A new version of TEMDM Spectrum Imager is coming! We decided to separate the treatment of spectrum-images and 4DSTEM datasets. A new tool, TEMDM 4Diffractor, is now available for the latter. Given the very different nature of the data, these two tools will evolve along distinct directions…
One evening, I knocked on James’s door. After a distracted “Please…” I entered, only to find him in an unusual situation: sitting on the floor, completely absorbed in building a model of an old sailing ship. He looked so much like a child at play that I couldn’t help but laugh. “Back to…”
TEMDM releases a new free-downloadable software package – “STEM Corrector”! Built on a modern Python-based platform, it overtakes the functionality of the former “temDM STEMCOR” plugin and makes operation much more convenient and transparent, while implementing and extending the earlier features.
Countless times, James Bond had guided my thoughts and taught me lessons I would never forget. However, I take pride in the fact that, on one occasion, I managed to help him out of a rather intricate situation. I happened upon James standing in the middle of a busy road, completely oblivious to the torrent…
TEMDM Spectrum Imager is updated! The interface is completely redesigned to better match modern standards and improve user comfort. The internal structure has been reworked for greater stability and several bugs have been fixed. Download the latest version at /msa/.
Upon entering the room, I was startled to find James Bond on all fours, frantically crawling on the floor. Fear gripped me as I wondered if the building was besieged by enemies. “What’s wrong? Are we under attack?” I stammered, my voice barely audible…
One of the most exhilarating scenes in spy movies is the daring escape of a secret agent amidst a hailstorm of enemy gunfire. A cunning agent avoids a direct path, instead weaving through a serpentine course that makes targeting him a daunting task. James interjected,…
What was never clear to me about James Bond’s personality was why he was dubbed ‘agent 007.’ My colleagues jest that I possess zero motivation, zero concentration, and seven brilliant ideas per decade, he said. This story explores indolence, effort and efficiency…
temDM Spectrum Imager is updated! Development focused on 4D STEM treatment, in particular pivot correction, which greatly improved the interpretability of PCA results. The internal structure has been changed substantially and several bugs fixed.
I’ve always admired James Bond’s knack for wriggling out of impossible situations. “It’s quite remarkable how smoothly you scale fences, leap from windows, and bulldoze through walls,” I told him. This story turns that metaphor toward dimensionality reduction…
TEMDM Spectrum Imager is updated! Version 1.3 can load 4D STEM data from dm3/dm4 and EMPAD formats and visualize data features with a virtual aperture. Since 4D STEM data are often huge, special care has been taken to make their handling convenient.
Once, I asked James Bond where his most difficult mission took place — Turkey, Mexico, or Russia? “In Great Britain, when I was promoted to the central analytical office of MI-6,” he replied. This post connects that story to the question of how accurate PCA can be.
temDM Spectrum Imager is updated! Version 1.2 dramatically improves data visualization in the latent factor space with 2D and 3D viewers. Data clustering is made easier, and pop-up help has been added for tool buttons and main widgets.
Once, I asked James Bond what was most important for a secret agent: shooting smartly or running quickly. “None of them,” Bond answered. This story uses that conversation to illustrate differences between ICA and PCA in data analysis.
temDM Spectrum Imager is updated! Version 1.1 fixes bugs and inconveniences of the first release and adds new features. Spectrum Imager remains free to download and is equipped with an easy-to-use, transparent installer that allows for clean uninstalling.
This story takes us back to a time when James Bond was sent undercover as an MI-6 agent to a highly classified school. He tracked student grades in large tables, using them to reveal hidden trends — much like PCA reveals trends in complex datasets.
You’ve probably heard about Principal Component Analysis (PCA) and how it can be used to clean up noisy datasets. But how does it actually work? And can it eliminate all the noise, or just a fraction? This post walks through these questions with practical context.
