“Adjust images - Set min and max layer-wise”ī.“Adjust images - Enhance contrast layer-wise”.Use the built-in commands from the right-click menu, such as: Then you have two general (non-exclusive) options:Ī. Now to correct the contrast, first re-enable mipmaps by going again to “Display - Properties…” and checking the “enable mipmaps” checkbox. “enable mipmaps” is not checked, so that it is disabled.īeware that you will not be able to browse quickly through layers while importing, given that mipmaps will not be generated.The goal is to avoid generating mipmaps multiple times, which may be very time consuming. “Prepaint” is not checked, so that it is disabled.įor importing large collections of images and editing them immediately afterwards.“snapshots mode” is set to “Disabled”, or at most to “Outlines”.Right-click on the canvas and choose “Display - Properties…”. Preparing TrakEM2 for best performance For fastest browsing through layers With the above settings, we have succesfully registered tens of thousands of sections with millions of images in TrakEM2. -XX:+PrintGCDateStamps: see a record of when the GC is run.-verbose:gc: optional, see when the garbage collector runs.Clean up unused memory using parallel threads. -XX:+UseG1GC : use the concurrent garbage collector.Note it’s the same amount as the intial heap size, so that the heap cannot be resized. -Xmx500g: use a maximum heap size of 500 Gb.start fiji with 500 Gb of RAM preallocated to it) -Xms500g : use an initial heap size of 500 Gb (i.e.ImageJ-linu圆4 -dry-run | sed 's/-Xincgc/-XX:+UseG1GC -verbose:gc -XX:+PrintGCDateStamps'/ > launcher.sh The following configuration has been tested in a machine with 256 CPU cores and 1 TB of RAM, running Ubuntu 22.04, with the latest 1.8.0 JVM: Running fiji for heavy-duty, memory-intensive, high-performance TrakEM2 tasks TrakEM2 tutorials with video tutorials.xml file onto the toolbar, or via “File - Open”. Open an existing project by dragging its.Create new projects from “File - New - TrakEM2 (blank)”.TrakEM2 interacts with the 3D Viewer for visualization of image volumes and 3D meshes. Semantic segmentation: order segmentations in tree hierarchies, whose template is exportable for reuse in other, comparable projects.Image Annotation: floating text labels.3D Visualization: interacting with the 3D Viewer plugin, TrakEM2 displays image volumes and 3D meshes of all kinds.Image Registration: register floating image tiles to each other using SIFT and global optimization algorithms.Measurements: volumes, surfaces, lengths, and also measurements via ImageJ ROIs.Skeletonize entire neuronal arborizations and represent synapses with relational connector objects. Segmentation: manually draw areas across stacks, and sketch structures with balls and pipes.TrakEM2 is an ImageJ plugin for morphological data mining, three-dimensional modeling and image stitching, registration, editing and annotation.
