Using MATLAB to Analyze Data Stored On NEEScentral
Whether conducting large-scale physical tests or numerical simulations, data resulting from these research endeavors often require extensive analysis using a multitude of external tools to post-process the results and ultimately make sense of the significance of the research.
A common data mining tool used in the earthquake engineering community is MATLAB. This document demonstrates how a researcher can easily get data out of NEEScentral, bring it into MATLAB, perform calculations, and archive the processed data back into NEEScentral. The approach outlined in this document is only one method anticipated by NEESit for data usage. NEESit is currently working on methonds to automatically extract data from NEEScentral using web services or other scripts in order to make the process more automated.
This document provides background information about NEEScentral and in particular where in the NEES data model data files are stored, describes how users can upload and download data to and from NEEScentral, and provides sample scripts for MATLAB to do simple manipulations of the data.
