An R implementation of these classifiers and the overall computational approach is available as the MetaClean package at. As a complementary approach, applying our framework to peaks retained after filtering by 30% RSD across pooled QC samples was able to further distinguish poorly integrated peaks that were not removed from filtering alone. The best performing classifier was found to be a combination of the AdaBoost algorithm and a set of 11 peak quality metrics previously explored in untargeted metabolomics and proteomics studies. These classifiers were compared to using a residual standard deviation (RSD) cut-off in pooled quality-control (QC) samples, which aims to remove peaks with analytical error. Specifically, we comprehensively and systematically compared the performance of 24 different classifiers generated by combining eight classification algorithms and three sets of peak quality metrics on the task of distinguishing reliably integrated peaks from poorly integrated ones. To address this problem, we propose a computational methodology that combines machine learning and peak quality metrics to filter out low quality peaks.

As a result, the output of these pre-processing software may retain incorrectly calculated metabolite abundances that can perpetuate in downstream analyses. To sum it up, MetaClean is a useful and easy to handle program that can successfully assist you in editing the information of your PDFs or your Microsoft Office and OpenOffice files, with just a few keystrokes required.Despite the availability of several pre-processing software, poor peak integration remains a prevalent problem in untargeted metabolomics data generated using liquid chromatography high-resolution mass spectrometry (LC-MS). Other potential details that you can remove or modify are the ‘Last Printed’ date, the application it was used to create it with or any comments. After inputting the targeted files, even in mixed formats, you can click on each item and reveal its specific information.Īs such, you can change or erase the ‘Title’, ‘Subject’ or ‘Author’ of a document, but also the ‘Creation’ and ‘Modification Date’, ‘Keywords’, ‘Manager’, ‘Company’, ‘Custom Properties’, ‘Category’, ‘Status’ and even the person to have altered the file last. MetaClean supports a wide range of formats, including Microsoft Office (Word, Excel, PowerPoint, Visio) files, OpenOffice (ODS, ODT, ODP) documents and PDFs. At the same time, the tool supports drag and drop operations, so you can also resort to this alternative for loading your files. In order to add the items you wish to work with into MetaClean, you can click on the ‘Load Documents’ button, then browse through your computer and locate the targeted files, being able to open several at once. Effortlessly edit the metadata of your documents The main window features a panel where all the added files will be listed, while on the right-side, you will be able to read each document’s information, including several important details that you may not want to make public, should you share the file with other people. The utility features a simple and easy to understand user interface, enabling even the less experienced to handle it immediately after installation. MetaClean is an intuitive and reliable piece of software developed to help you access and edit the metadata from your documents, be they in PDF, DOC, ODT or other similar formats, without too much trouble for you.
