## Chapter 19: Working With Analysis Projects

An Analysis Project folder is a special type of folder that can be used to store all of the data pertaining to a simulation. You can track dependencies of objects contained within the project or across multiple projects, and update the analysis if an upstream dependency has changed.

Using an Analysis Project folder to manage your data offers the following advantages:

- Like any other folder, an Analysis Project folder allows you to manage all the inputs, outputs, reports and other documents that are associated with an analysis in a single container. If you have some input files that are common to multiple analyses, for example, you can create a shortcut to these files and place the shortcut in the project folder. When you download the project, the files or folders referenced by the shortcut will also be downloaded. This means that EKM maintains only one instance of the input files even if they are used in multiple places. When you download a project, you will receive all of the dependent files required to run the analysis.

- You can specify inputs and outputs for an analysis, or its pedigree, and track the dependencies graphically. The dependency diagram will clearly indicate the upstream files that have been modified and make the current analysis out-of-date. This gives you added confidence when you are using the data to perform further analysis or make design decisions. See Specifying Analysis Project Pedigree (Inputs and Outputs) to specify the pedigree for the project and Specifying File Dependencies for a file contained within the project.

- You can execute an analysis automatically using a process template that you have defined. EKM will create a process and start it. You can view the progress of the process on the Processes/Process Monitor page. See Updating an Analysis Project Folder.

You can either use the built-in Analysis Project type or create a new custom data type that extends from it to define your particular analysis project. If you use the built-in type, you will need to manually specify the inputs, outputs, and execution settings (for automatic execution) of each analysis “instance”, as explained above. If instead, you create a custom type, you can predefine this information for the custom type so that it can be used by all instances of that type. This eliminates the need to enter this information for each analysis. Furthermore, you can specify the project folder structure and custom metadata for the analysis using a custom type. See the Defining Custom Analysis Types chapter in the Administration Guide for details on creating custom analysis projects in EKM.

This chapter presents information on how to create an Analysis Project folder, and manage your simulation-based analysis data that is contained within it. Topics include:
