GRITS Toolbox is a modular software suite for processing, annotating and archiving of glycomics data with a focus on MS data.The software allows users to upload their instrument MS data files in open file formats (either as mzXML or mzML) and annotated them using the integration annotation module Glycomics Elucidation and Annotation Tool (GELATO). GRITS Toolbox can process different types of MS data including MS profiling data, MS/MS data from direct infusion experiments, LC/MS/MS data and TIM data. To propose glycan structures as annotations GRITS Toolbox uses a set of databases which have been curated by experts using our Qrator software. Automatically annotated data can than be reviewed by the user and annotation can be changed depending on the users expertise. If MSn data is available users can review the fragment annotation of these spectra as well and use them to refine the structure annotation. Results can be exported to Microsoft Excel files and post-processed with other software tools. It is also possible to study the annotations of multiple experiments side by side to see the changes in glycosylation between the samples. This kind of report can be exported to Microsoft Excel as well.
In addition to the processing, evaluation and browsing of the experimental data GRITS Toolbox can also be used to archive meta data along with the experiment data. This provides a way to archive an complete overview of the experiment rather than storing different parts of information in multiple locations which will make it complicated to find all pieces later. The metadata that can be handled by GRITS Toolbox are:
All information added to GRITS Toolbox can be downloaded from the software (e.g. files) or exported into reports (e.g. PDF or Word).
