Restricting the alignment to a region of interest in TrakEM2

Posted on 3. June 201919. November 2022by Stefan

After a first rough alignment (see here), it makes sense to start a second run only using a region of the stack containing the object of interest in all images. By this, the number of detected features will automatically increase even if the standard preset settings are used.  Use the rectangle tool (upper left) to […]

Aligning an image stack in TrackEM2

Posted on 1. June 201930. June 2022by Stefan

This a very brief, compact introduction on how to align image stacks in TrakEM2. 1.open Fiji (download: https://imagej.net/Fiji/Downloads) : choose File in the sidebar –>Import –> Image Sequence 2. Choose the folder with all your images (mac) or open the folder and click on the first image (PC) and select the open button below. 3. the following […]

About me

Hi, I am Stefan Fischer. I am biologist at the University of Tübingen and Head of Tübingen Structural Microscopy Core Facility (TSM). My methodological interest is set on electron microscopy. Furthermore I do focus on 3D techniques, be it on basis of semi-thin sections (LM), Ultra-thin sections (ssTEM) and also MicroCT data. For that reason I developed a strong interest in open source software packages and image analysis in order to automate (or semi-automate) some of the tedious parts of my workflows.
