The Brain Imaging Data Structure (BIDS) standard has been developed to facilitate this task, but researchers are still facing the challenge of reusing scripts to analyse data coming from different projects or different centres. Here, our goal was to develop a tool, BIDS Manager-Pipeline, to process automated analyses using open-source research software solutions on several subjects at the same time. BIDS Manager-Pipeline builds upon BIDS Manager, a software recently developed in our lab to collect, organise, and manage multimodal multicentre datasets. When processing data, BIDS Manager-Pipeline coordinates the use of several modules originating from different software environments and executable programs and can thus be considered as a bridge between BIDS datasets and software solutions. Through a graphical user interface, users can filter the subjects of interest in the dataset by ID or by other subject criteria and common input analysis parameters. BIDS Manager-Pipeline first controls whether the selected values can be applied to the selected subset, provided the inputs and the outputs, and then run the process on all selected data. The results of analyses are stored using specifications for BIDS derivatives. In addition, BIDS Manager-Pipeline creates a table gathering the different metrics resulting from the analyses across subjects, for later statistical analyses. In short, BIDS Manager-Pipeline allows processing data from large cohorts, either in basic neuroscience or in clinical research. This framework can take advantage of tools developed by the neuroscience community, by centralizing and facilitating their use.</p></div>","PeriodicalId":74295,"journal":{"name":"Neuroscience informatics","volume":"2 2","pages":"Article 100072"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772528622000346/pdfft?md5=0203a7753d0f04fe5ec794280e84c3bc&pid=1-s2.0-S2772528622000346-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49254611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brain tumor classification is mainly a helpful and widely desired process in the medical system. Brain tumor classification is a significant way to automatically categorize brain tumors images. Many methods have been introduced for solving the classification task with leverage low-level features. However, it has few limitations for achieving the higher accuracy of image tumor classification with minimum time. To overcome the issue, this study has proposed a novel technique called Regularized Anisotropic Filtered Tanimoto Indexive Deep Multilayer Perceptive Connectionist Network (RAFTIDMPCN), consisting of many layers of nodes for deeply analyzing the input and providing better classification results. The proposed architecture helps in improving the accuracy and reducing the time. The input layer receives the number of MRI images and natural image datasets collected from the dataset. Then the images are sent to the first hidden layer where the preprocessing is carried out to improve the image quality by removing the noise pixels using Regularized Anisotropic diffusion filtering technique. Followed by, shape, color, texture, and size features of input images are extracted in the second hidden layer. The classification is performed at the third hidden layer based on the Tanimoto similarity measure. Finally, the Heaviside step activation function is applied to obtain the classification results with higher accuracy. Experimental evaluation is carried out with different qualitative and quantitative results discussion by using brain tumor MRI dataset and natural image datasets. The obtained results indicate that the proposed technique provides better results in terms of Peak signal to noise ratio, accuracy, false-positive rate, time complexity, and space complexity. The analyzed results show the superior performance of our proposed RAFTIDMPCN technique accuracy by 6%, minimizes the false-positive rate by 40%, and time complexity by 11% in brain tumor detection when compared with the two state-of-the-art methods. This paper also presents several discoveries that could be helpful to the neurological community.</p></div>","PeriodicalId":74295,"journal":{"name":"Neuroscience informatics","volume":"2 2","pages":"Article 100063"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772528622000255/pdfft?md5=26063b38ab0cd63ca3f5df15f3448a87&pid=1-s2.0-S2772528622000255-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41380314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
