How do I import Campbell Scientific CR10x data into the GCE Data Toolbox?Īrray-based data from Campbell CR10x loggers require special processing, because the files lack a header and each row may contain a different number of variables representing different measurements. Importing and exporting data commands are used to load or save data stored in other formats, such as CSV text files, MATLAB arrays or specialized exchange formats. File > Load Data Structure) pertain to GCE Data Structures, which are the native MATLAB variables used for storing data, Q/C information and metadata (see the data model page for more information). Loading and saving data in the Dataset Editor application (e.g. What's the difference between loading and importing data, or saving and exporting data? mat files stored in directories included in localpaths.txt will have higher priority than the default GCE Data Toolbox directories, so use distinct file names unless you intend to over-ride native toolbox files with customized versions. C:\Users\Joe\Documents\MATLAB\workflowsĬ:\Users\Joe\Documents\MATLAB\myfunctions List one directory per line with no quotes or delimiters, e.g. To add local directories to the toolbox automatically on start up, create a text file named 'localpaths.txt' containing fully qualified paths appropriate for your system and save it to your default user path (type 'userpath' in the command window) or the top-level toolbox directory. In fact, the best practice is to store all custom and localized toolbox files in a directory outside of the default GCE Data Toolbox directories to streamline updating to new toolbox versions without losing your customizations. You can store workflow functions or scripts and other toolbox extensions in any directory available in the MATLAB search path (use the path browser GUI or type 'path' in the command window to view the active path). These steps can be coded in a MATLAB Desktop shortcut similar to the following: curpath = pwd %cache working directoryĬd 'C:\MATLAB\GCE_Toolbox' %change to toolbox directoryĬd(curpath) %change back to the original directoryĬlear curpath %clear the curpath variable from memoryĭo I have to store my custom workflows in the toolbox /workflows directory? The simplest way to accomplish this is to save the working directory in a variable, change to the toolbox directory to run startup.m, then change back to the original directory. How can I start up the GCE Data Toolbox without changing my working directory? In fact, manually registering GCE Data Toolbox directories in the permanent path can lead to problems with future toolbox updates, because startup.m will not alter the path if any toolbox directories are found to prevent duplication, preventing any new sub-directories from being added. The needed directories will be added to the run-time path automatically when startup.m is called from the toolbox root directory. Statistics, Curve Fitting, Signal Processing) could also be called when adding calculated columns, correcting sensor drift, filling missing values or in custom QA/QC rules.ĭo I need to add the GCE Data Toolbox directories to the permanent MATLAB path? Specialized functions in other toolboxes (e.g. No, but it can take advantage of functions in the Database Toolbox to exchange data with relational database management systems, including MySQL, Postgres, Microsoft SQL Server and Oracle. Whenever possible, MATLAB should be run on 64-bit operating systems to avoid this fragmentation issue.ĭoes the GCE Data Toolbox require any specialized MATLAB toolboxes?

However, memory fragmentation on 32-bit Windows systems can limit the maximum array size available in MATLAB sessions to 3 GB of RAM, causing certain memory intensive Q/C and geographic operations to fail.
The GCE Data Toolbox does not impose any additional requirements beyond MATLAB. MATLAB hardware requirements and recommendations are listed on the Mathworks web site. What kind of computer hardware do I need to run MATLAB and the GCE Data Toolbox? The GCE Data Toolbox leverages hundreds of built-in MATLAB functions and libraries that are not available in Octave and other alternative programs that support MATLAB-like syntax. The GCE Data Toolbox is a library of MATLAB functions and data files, and requires a licensed copy of MATLAB (version 7.9/R2009b or higher) to run.Ĭan I use an open source MATLAB clone (e.g.
