The HydroATLAS database is distributed in large file sizes due to the enriched attribute information. Users who only need geometric information and digital vector maps of sub-basin boundaries, river network lines, and lake shorelines may prefer to download the HydroBASINS, HydroRIVERS, or HydroLAKES products instead.
Note: Users who only need geometric information and digital vector maps of sub-basin boundaries, river network lines, and lake shorelines may prefer to download the smaller HydroBASINS, HydroRIVERS, or HydroLAKES products instead.

If True, lateralized atlases of cort or sub with maxprob will bereturned. For subcortical types (sub-maxprob), we split everysymmetric region in left and right parts. Effectively doubles thenumber of regions.
For some atlases, it can be the case that some regionsare empty. In this case, no voxels in themap are assigned to these regions. So the number ofunique values in the map can be strictly smaller than thenumber of region names in labels.
If you are interested in participating, you are invited to download the training set, including both CT perfusion scans as well as the corresponding expert segmentations of the infarct lesions. This will allow you to validate and optimise your method as much as you favour.
There you will find explanations on how to register, how to download the data, and how as well as in which format to upload your results. Furthermore, the evaluation scores obtained by each team will be listed there.
At the default zoom level of the atlas, basic outlines representing the footprints for available CORONA images are displayed. As users zoom in to a larger scale, the CORONA images and archaeological sites become viewable.
Map layers can be toggled using the Map Contents menu. Some map layers are expandable, allowing sub-layers to be turned on or off. Use the plus sign(+) next to a layer to access sub-layers. Use the blue down-arrow next to an image to download the source data.
Due to the imaging geometry of CORONA, each image has a different, but compatible photogrammetric model. These models aim to reconstruct image-ground relations in the imaging sensor and are prone to variations as some of the physical camera parameters are not available. Therefore, spatial accuracy is not standard throughout the Atlas, and two CORONA images overlapping in an area may not perfectly match. In these cases selecting an image to download can be determined by visual inspection with the tools provided in the Atlas.
As an emerging standard, each National Imagery Transmission Format (NITF) file available for download contains one unprocessed CORONA image, along with a replacement sensor model (in the form of Rational Polynomial Coefficients - RPC) used to map the image to the ground. RPC information generated from inhouse control point measurements and software. Once fully downloaded, these images can be viewed in many Geographic Information Systems (GIS) software and remote sensing platforms. These images are not orthorectified, however, and require further processing. To help facilitate this process, we have prepared, and made available for download, SRTM DEM files for each Corona revolution HERE. Information on using ArcGIS to orthorectify the NITF files using the provided elevation data can be found HERE.
Not all images included in the atlas have been manually assessed for quality of alignment. Please contact us HERE if you discover any images that are considerably out of alignment with the underlying imagery. Sorry, we had to disable the error reporting form because of continued abuse by certain individuals.
The BMA 2017 Ex Vivo (Space 1) atlas release is a multi-modal Nissl & MRI 3D brain atlas where the Nissl histology data has been normalized to the MRI shape. The brain region annotation is now version 6.2, revised from the Hashikawa et. al (2015). The atlas contains over 200 cortical and sub-cortical annotations per hemisphere and improves upon the work of Hashikawa et al. (2015). State-of-the-art registration algorithms were used to register the different data modalities to one another and to remove noise and artifacts. The original Nissl and parcellation data (for one hemisphere only) were warped to match the ex-vivo MRI data, then mirrored across the sagittal plane.
The BMA 2019 Ex Vivo (Space 2) atlas release builds on previous work and is composed of a population average ex-vivo MRI T2WI contrast with the BMA 2017 Ex Vivo dataset mapped to its shape.The release now includes cortical flat maps for the left and right hemispheres. These can be used for the projection and visualization of data in 2D. In addition, the dataset provides 3D transformation files for mapping between Space 1 and Space 2.
The brain atlases can be used for tasks such as brain region identification for experiment planning, large-scale connectomics and brain simulation. They are being used widely throughout the Brain/MINDS project as a way to integrate heterogeneous data from a wide number of experiments.

The USCLobes atlas segments the brain into larger regions than those provided by the default BrainSuite atlases. The detailed description of the atlas development can be found in the description page of the BCI-DNI_brain atlas description.
A high-resolution 3D MPRAGE scan (TE=4.33 ms; TR=2070 ms; TI=1100ms; flip angle=12 degrees; resolution=0.5470.5470.802 mm) was acquired on a 3T Siemens MAGNETOM Tim Trio using a 32-channel head coil. Data were acquired 5 times and averaged. The subject is a typical right-handed woman in her mid-thirties with a brachiocephalic brain and no rare anomalies.Preprocessing and labeling of the MPRAGE image was performed using BrainSuite [1,2]. This MRI volume was used to generate the BCI-DNI atlas as described here.
This atlas contains maps for the Caribbean as a whole and individual sub-regions. Thisatlas has been divided into four PowerPoint presentation files, with hyperlinks betweenthe files. To view this atlas, do one of the following: Download the four individual files below (Parts A-D) to the same directory on your computer and open that directory or
Change to the 'document/reglstrm' directory on the CD
Within that directory, select and open the file 'hurratlas7a.ppt'.
Island-specific atlases are presented in separate PowerPoint files. An introductory powerpoint presentation (a variation on Part A above) provides an important introduction to theinformation contained in the following atlases.

FSL comes bundled with a collection of NIFTI templates and atlases. A variety of probabilisticand discrete atlases are included, comprising cortical, sub-cortical, andregional parcellations. It is also possible to add your own atlases toFSL.
All of the atlases included with FSL 6.0.4 have beenaligned to the MNI152 standard template. This means that anyimages which you wish to query using these atlases must be alsoregistered to MNI152 space.
The list on the left allows you to select the atlases that you wish to query -click the check boxes to the left of an atlas to toggle information on and offfor that atlas. The Harvard-Oxford cortical and sub-cortical structuralatlases are both selected by default.
The panel on the right displays information about the current display locationfrom each selected atlas. For probabilistic atlases, the region(s)corresponding to the display location are listed, along with theirprobabilities. For discrete atlases, the region at the current location islisted.
Some of the atlases included in FSL (e.g. the Talairach) containa large number of regions. Generating and displaying the regionlist can therefore take some time, so please be patient the firsttime that you select an atlas!
When you select an atlas in this list, all of the regions in that atlas arelisted in the area to the right. Again, the checkbox to the left of eachregion name toggles an overlay for that region on and off (either avolume or mask overlay,depending on whether the atlas is probabilstic or discrete). The + button nextto each region moves the display location to the (approximate) centre of thatregion.
When you type some characters into the search field, the region list will befiltered, so that only those regions with a name that contains the charactersyou entered are displayed. The atlas list on the left will also be updated sothat any atlases which contain regions matching the search term arehighlighted in bold.
The atlas management tab displays a list of all loaded atlases, and allows youto add and remove atlases from FSLeyes. The name of each atlas is shown in thelist, but you can click and hold on an atlas to display the path to the atlasspecification file.
You can load a new atlas into FSLeyes by clicking the + button, and selectingthe FSL atlas specification file which describes the atlas - see the page oncustomising FSLeyes for details. You can remove an atlasfrom FSLeyes by selecting it in the list and clicking the - button *.
A note for end users:The KMLs provided below are estimates of locations and times of the ICESat-2 reference ground track and beams. Prior to April 1 2019, we were not pointing at our RGT and as such, data collected during that time was not along planned RGTs and these KMLs should not be used in an attempt to sync with data collected between October 2018 and April 1, 2019. The geolocation information provided in ICESat-2 data available for download at NSIDC reflects where data was actually collected. 2ff7e9595c
