The Ivy Glioblastoma Atlas Project (Ivy GAP) is a detailed anatomically based transcriptomic atlas of human glioblastoma tumors. As collaborators, the Ivy Foundation funded the Allen Institute and the Swedish Neuroscience Institute to design and create the atlas. The Paul G. Allen Family Foundation also supported the project. This resource consists of a viewer interface that resolves the manually- and machine-annotated histologic images (H&E and RNA in situ hybridization) at 0.5 µm/pixel, a transcriptome browser to view and mine the anatomically-based RNA-Seq samples, an application programming interface, help documentation that describes the methods and how to use the resource, as well as SNP array data and the supporting longitudinal clinical information and MRI time course data. The resource is made available to the public without charge as part of the Ivy GAP (http://glioblastoma.alleninstitute.org/) via the Allen Institute data portal (http://www.brain-map.org), the Ivy GAP Clinical and Genomic Database (http://ivygap.org/) via the Swedish Neuroscience Institute (http://www.swedish.org/services/neuroscience-institute), and The Cancer Imaging Archive (https://wiki.cancerimagingarchive.net/display/Public/Ivy+GAP). The Ivy GAP processed data at GEO includes normalized RNA-Seq FPKM files used for analysis in "An anatomic transcriptional atlas of glioblastoma,” which is under review. Other processed data files as well as sample and donor meta-data and QC metrics are available at http://glioblastoma.alleninstitute.org/static/download.html. The raw RNA-Seq and SNP array data will be submitted to dbGaP.

Abstract:
The Ivy Glioblastoma Atlas Project represents a fundamental tool for investigating the cellular and molecular underpinnings of glioblastoma. It offers an accessible online atlas and database containing valuable clinical and genomic information, which will undoubtedly facilitate future studies on glioblastoma pathogenesis, diagnosis, and therapeutic approaches. Glioblastoma is a highly aggressive brain tumor with a bleak prognosis, and its intricate molecular and cellular characteristics have not been fully elucidated in relation to conventional diagnostic histologic features. The dataset provided is comprised of de-identified clinical data pertaining to both patients and tumors.
Inspiration:
This dataset was uploaded to UBRITE for GTKB project.

This dataset comprises two paired sets of expert segmentation labels for tumor sub-compartments of the pre-operative multi-institutional scans of the Ivy Glioblastoma Atlas Project (Ivy GAP) collection of The Cancer Imaging Archive (TCIA). These labels have been approved by independent expert board-certified neuroradiologists at the Hospital of the University of Pennsylvania and at Case Western Reserve University. Furthermore, for each of the paired sets of approved labels, a diverse comprehensive panel of radiomic features is provided, along with their corresponding skull-stripped and co-registered multi-parametric magnetic resonance imaging (mpMRI) volumes (i.e. native (T1) and post-contrast T1-weighted (T1-Gd), T2, T2-FLAIR), in NIfTI format. The pre-operative mpMRI scans were identified in the Ivy GAP collection via radiological assessment. These scans were initially skull-stripped and co-registered to a common anatomical atlas (provided within this dataset), before their tumor segmentation labels were produced following a consistent annotation protocol across the two institutions. The final labels were used to extract a rich panel of radiomic features through the Cancer Imaging Phenomics Toolkit (CaPTk), comprising intensity, volumetric, morphologic, histogram-based, and textural parameters compliant with the Image Biomarker Standardisation Initiative (IBSI), as well as through a 3D Slicer extension for the novel CoLlAGe feature family. Radiomic features robust to variability in segmentations were then identified following a statistical robustness analysis. The approved expert segmentation labels should enable quantitative computational and clinical studies without the need to repeat manual annotations, whilst allowing for comparison across studies. They can also serve as a set of manually-annotated gold standard labels for performance evaluation in computational competitions, such as the http://braintumorsegmentation.org/" rel="nofollow">International Brain Tumor Segmentation (BraTS) challenge. The provided panel of robust radiomic features may facilitate research integrative of the molecular characterization offered by the Allen Institute, and hence allow associations with molecular markers (radiogenomics), clinical outcomes, treatment responses and other endpoints, by researchers without sufficient computational background to extract such features. The complete reproducibility analysis can be found in the associated publication citation found in the “Citations & Data Usage Policy”. Specifically, the released data comprises of 1) the available expert segmentation labels of the various tumor sub-compartments performed at each institution (i.e. 34 subjects segmented at UPenn, 34 subjects segmented at CWRU), with a total of 37 subjects (including 31 paired segmentations performed at both UPenn and CWRU), in the original space they were created (i.e., SRI for UPenn and MNI for CWRU), with 2) their corresponding co-registered and skull-stripped structural mpMRI scans (i.e., in SRI for UPenn and in MNI for CWRU), 3) the paired expert segmentation labels that were available for the 31 subjects, all being co-registered in the SRI atlas, 4) the corresponding SRI and MNI anatomical atlas files that we employed, 5) the complete set of 11,700 extracted radiomic features per subject, for each of the 31 included subjects, 6) the metadata relating to the metrics we utilized for the evaluation of the inter-rater agreement, as well as 7) the parameters used for the radiomic feature extraction and the correlation analysis results for identifying robust radiomic features, for the 28 subjects, and finally 8) the specific identified robust/reproducible radiomic features. All image related files are provided in NIfTI format, while the metadata files are provided in tabular formats (.xlsx and .csv).

This dataset contains the ONCOhabitats processing results for the patients with complete pre-surgical MRI (T1, T1-Gd, T2, FLAIR and DSC perfusion) included at the Ivy Glioblastoma Atlas Project (Ivy GAP) dataset.
The ONCOhabitats platform includes two main services:
Preprocessing: Several artefacts are corrected in this module such as magnetic bias field inhomogeneities, noise or spike artifacts. Additionally, automated registration, brain extraction and intensity normalization are conducted to generate a consistent multi-parametric high quality MRI of the brain.
Segmentation: This module implements a state of the art 3D Convolutional Neural Network (CNN) classifier based on a U-Net architecture to delineate the tumor tissues.

Segmentation: This module implements a state of the art 3D Convolutional Neural Network (CNN) classifier based on a U-Net architecture to delineate the tumor tissues.
DSC Perfussion Quantification: This module quantifies the hemodynamic indices derived from of the Dynamic Susceptibility Contrast perfusion sequence. Cerebral Blood Volume (CBV), Cerebral Blood Flow (CBF), Mean Transit Time (MTT) are computed.
Hemodynamic Tissue Signature: Hemodynamic MTS provides an automated unsupervised method to describe the heterogeneity of the enhancing tumor and edema tissues, in terms of the angiogenic process located at these regions. We consider 4 sub-compartments for the GBM, closely related to the more angiogenic enhancing tumor part, the less angiogenic enhancing tumor area, the potentially tumour infilatrated edema and the pure vasogenic edema.
For each patient, we include a PDF report containing an analysis summary; two folders with the resulting images in MNI and native spaces; and a third folder with the transformation matrices.

We present two databases of phenolic content measurements of three ivy species (Hedera L., Araliaceae) that are naturally distributed across continental Europe: H. helix, H. hibernica, and H. iberica. We sampled a total of 82 ivy populations in the wild in the Iberian Peninsula representing adequately the natural distribution of the species in the sampled area and the global distribution of H. iberica, endemic of the south-west of the Iberian Peninsula. In each population five individuals were sampled whenever it was possible and a leaf from a vegetative branch (VL) and another from a reproductive branch (RL) were collected for phenolic measurement. Geographic information (latitude, longitude and altitude) was retrieved for each population. Phenolic content was estimated as the absorbance at 329 nm per mg of fresh leaf weight (A329), as the absorption peak of phenylpropanoids, the most abundant phenolic compounds of ivies, is located at this wavelength (Murray & Hackett, 1991). As an additional estimate we measured the area under the absorbance curve for the interval 280-400 nm per mg of fresh leaf weight (AUC280-400) following Del-Castillo-Alonso et al. (2015). Climatic information for each locality was retrieved for 22 macroclimatic variables available in WorldClim 2.1 with a 2.5min resolution, including 19 bioclimatic variables, solar radiation, water vapor pressure and wind speed (Fick and Hijmans, 2017). The first version of the presented databases (v1) includes all the geographic, phenolic and climatic information used for the analyses in Gallego-Narbón et al. (under review). All the samples collected are available at the herbarium of Universidad Autónoma de Madrid (MAUAM).
