Data and code to analyze the statistical skill of capturing observed bleaching events globally using sea surface temperatures. The analysis here quantifies the hits, misses, false alarms, and correct negatives, and then applies these results to a variety of weather-forecasting metrics to quantify the skill of predicting bleaching. Finally, adjustments to sea surface temperature-based heat stress metrics are evaluated to test if prediction skill can be improved above typical approaches.

The GenRot program takes a typical Gaussian .gjf file (connectivity written after XYZ) as input, and generates new XYZ data based on inputs from the user. After opening the file in the program, the user clicks on 4 atoms to define a dihedral angle and determines the degree of rotation they wish for that angle. This is repeated until all the dihedral angles that the user wants to rotate have been defined. The program will rotate each of the dihedral angles 360/n times, where n is the rotation degree from the user input. If n, is, for example, 33, then 360/33=10.9, the number will be rounded down to 10. If the user wants to rotate four dihedral angles 120 degrees each, the program generates (360/120)^4 = 81 rotamers. It is possible for the user to change the route section of the Gaussian input file, in case there was an error, and also to append text to the end of the file. When all the dihedral angles have been chosen, and the desired rotation defined, one simply clicks “Generate files”, and all files are generated into folder specified by the user. While the program reads Gaussian type input file only, it can in principle generate files with any information before and after the XYZ data, and may be suited to generate input files for other quantum calculation software.

Recognition of different genomic signals and regions (GSRs) in the DNA is helpful in gaining knowledge to understand genome organization and gene regulation as well as gene function. Accurate recognition of GSRs enables better genome and gene annotation. Although many methods have been developed to recognize GSRs, their pure computational identification remains challenging. Moreover, various GSRs usually require a specialized set of features for developing robust recognition models. Recently, deep learning (DL) methods have been shown to generate more accurate prediction models than the ‘shallow’ methods without the need to develop specialized features for the problems in question. Here, we explore the potential use of DL for the recognition of GSRs. We developed DeepGSR, an optimized DL architecture for the prediction of different types of GSRs. The performance of the DeepGSR structure is evaluated on the recognition of polyadenylation signals (PAS) and translation initiation sites (TIS) of different organisms: human, mouse, bovine and fruit fly. The results show that DeepGSR outperformed the state-of-the-art methods, reducing the classification error rate of the PAS and TIS prediction in the human genome by up to 29% and 86%, respectively. Moreover, the cross-organisms and genome-wide analyses we performed, confirmed the robustness of DeepGSR and provided new insights into the conservation of examined GSRs across species.

Abstract: Discriminating the causative disease variant(s) for individuals with inherited or de novo mutations present one of the main challenges faced by the clinical genetics community today. Computational approaches for variant prioritization include machine learning methods utilizing a large number of features, including molecular information, interaction networks, or phenotypes. Here, we demonstrate the PhenomeNET Variant Predictor (PVP) system that exploits semantic technologies and automated reasoning over genotype-phenotype relations to filter and prioritize variants in whole exome and whole genome sequencing datasets. We demonstrate the performance of PVP in identifying causative variants on a large number of synthetic whole-exome and whole-genome sequences, covering a wide range of diseases and syndromes. In a retrospective study, we further illustrate the application of PVP for the interpretation of whole-exome sequencing data in patients suffering from congenital hypothyroidism. We find that PVP accurately identifies causative variants in whole exome and whole genome sequencing datasets and provides a powerful resource for the discovery of causal variants.

Background Mining high-throughput screening (HTS) assays is key for enhancing decisions in the area of drug repositioning and drug discovery. However, many challenges are encountered in the process of developing suitable and accurate methods for extracting useful information from these assays. Virtual screening and a wide variety of databases, methods, and solutions proposed to-date, did not completely overcome these challenges. This study is based on a multi-label classification (MLC) technique for modeling correlations between several HTS assays, meaning that a single prediction represents a subset of assigned correlated labels instead of one label. Thus, the devised method provides an increased probability for more accurate predictions of compounds that were not tested in particular assays. Results Here we present DRABAL, a novel MLC solution that incorporates structure learning of a Bayesian network as a step to the model dependency between the HTS assays. In this study, DRABAL was used to process more than 1.4 million interactions of over 400,000 compounds and analyze the existing relationships between five large HTS assays from the PubChem BioAssay Database. Compared to different MLC methods, DRABAL significantly improves the F1Score by about 22%, on average. We further illustrated usefulness and utility of DRABAL through screening FDA approved drugs and reported ones that have a high probability to interact with several targets, thus enabling drug-multi-target repositioning. Specifically, DRABAL suggests the Thiabendazole drug as a common activator of the NCP1 and Rab-9A proteins, both of which are designed to identify treatment modalities for the Niemann–Pick type C disease. Conclusion We developed a novel MLC solution based on a Bayesian active learning framework to overcome the challenge of lacking fully labeled training data and exploit actual dependencies between the HTS assays. The solution is motivated by the need to model dependencies between existing experimental confirmatory HTS assays and improve prediction performance. We have pursued extensive experiments over several HTS assays and have shown the advantages of DRABAL. The datasets and programs can be downloaded from https://figshare.com/articles/DRABAL/3309562.
