This tutorial is going to describe comparing different data sets. In this example, we're going to compare data between various subjects.

The sample files can be downloaded here.

• Data:
  • Sub 01 CMZ
  • Sub 02 CMZ
  • Sub 03 CMZ
• Scripts:
  • Tag.v3s (Example script that can be used to tag the files)
  • Tag_Loop.v3s (Example script that can be used to tag the files using a For_Each loop)
  • Overlay.v3s (Example script that can be used to overlay the report template with another subject)
  • Overlay_Loop.v3s (Example script that can be used to overlay the report template with another subject using a For_Each loop)
• Report Templates:
  • Report_Template_ALL_FILES.rgt
  • Report_Template_Sub_01.rgt

The first step is to load the data. It's recommended that you use the CMO Library to view multiple CMZ files at once. Many users simply choose to do a File → Open if they're viewing two small files. This option works for smaller data sets, but it's really recommended to use the CMO Library instead.

1. CMO Library → Set CMO Library Path
   1. Select ..Comparing Data Sets\Data folder
   2. Click OK
2. CMO Library → Browse CMO Library
   1. Select Yes

More detailed instructions to load the CMO Library can be found here.

Once the data is loaded in the workspace, create three tags: - Sub_01 - Sub_02 - Sub_03

There are a few ways to create tags: (Choose one method of the following)

1. Manually add tags to the files or use the pipeline.
2. Use the Assign_Tags_To_File command to assign tags to subjects based on the filename. This can be done using the provided Tag.v3s file.
3. Using the For_Each command, you can loop over all the subjects in your workspace to create individual tags for them. This can be done using the provided Tag_Loop.v3s file.

Once the data has been loaded and tagged, create a report template that plots the data.

A. Open a report template that plots the signals you are interested in viewing (ex. Open provided Report_Template_ALL_FILES.rgt) B. Change the tag from ALL_FILES (or whatever you're currently plotting) to one of the tags you want to plot (ex. Sub_01) and set the line color to the same for both the right and left sides. a. Search/Replace:

a1. Old File Tag: ALL_FILES a2. New File Tag: Sub_01 a3. Click “Add»“ a4. Old Line Color: #109900 a5. New Line Color: Purple a6. Click “Add»“ a7. Old Line Color: #990000 a8. New Line Color: Purple a9. Click “Add»“ a10. Select “Entire Report” a11. Click “Replace”

D. Save report template (ex. Report_Template_Sub_01.rgt)

The step to overlay the subject data can be done manually (as described below), or using the pipeline (ex. provided scripts from download Overlay.v3s or Overlay_Loop.v3s).

A. Overlay Sub_02 on top of Sub_01 a. Overlay Report:

a1. Page No: ALL_PAGES a2. Identifier Type: TAG_NAME a3. Identifier Value: Sub_01 a4. New Tag: Sub_02 a5. New Color: Blue

B. Overlay Sub_03 on top of Sub_01 a. Overlay Report: a1. Page No: ALL_PAGES a2. Identifier Type: TAG_NAME a3. Identifier Value: Sub_01 a4. New Tag: Sub_03 a5. New Color: Cyan C. Display the tag name in the Legend of the report
