Installing NeuroMap and Decomposing Data

Overview

This article provides an introduction to installing and using NeuroMap, which is our motor unit decomposition software package. Through NeuroMap, you can decompose sEMG data files into individual motor units, offering powerful insights into neuromuscular control during complex movement. You will learn how to install NeuroMap, activate your NeuroMap license, and use NeuroMap to decompose data. Once you have successfully decomposed your data, refer to our Analyzing Decomposed Data in NeuroMap Explorer guide for more information on how to visualize and export your motor unit data.

Important

• This article assumes you have already collected NeuroMap-compatible data. For more information on how to collect NeuroMap-compatible data (See Collecting Data for Motor Unit Decomposition)

Information

• A high-performance processor will improve decomposition speed and reliability. NeuroMap is CPU-based only. It does not support GPU-accelerated processing.

System Requirements

Step-by-Step Instructions

Step 1: Installing and Activating NeuroMap

1. Installing NeuroMap

   1. Download the NeuroMap software package here:  This installer contains both NeuroMap and NeuroMap Explorer.

   2. Run the installer and follow the on-screen prompts

   3. Follow the prompt to install MATLAB Runtime

      1. Installing MATLAB Runtime is required in order to use NeuroMap

2. Activating your License

   2. After NeuroMap Installation, open NeuroMap

   3. A license agreement pop-up will appear and will display two codes

      2. Copy these codes and send them to Delsys Support

      3. You will receive two activation keys in return. Enter these codes, then click Activate.

Information

• Licensing is tied to the computer. You must repeat this process on each device where NeuroMap is installed.

• Licensing is only required for NeuroMap, not NeuroMap Explorer

Step 2: Using NeuroMap to Decompose Data

Important

• Not all EMG data can be decomposed into motor units. For more information on how to collect NeuroMap-compatible data (See Collecting Data for Motor Unit Decomposition)

1. Import your Data

   1. Click the Add Files button to add .HPF files

      1. You can import multiple files at the same time by holding “Ctrl” on your keyboard and left-clicking on each file you want to import.

   2. If desired, remove files by selecting them and clicking Remove Files.

Important

• Only .HPF files can be imported into NeuroMap. You must use Trigno Discover or EMGworks to collect .HPF files.

2. Preview your Data

   2. Once the files are imported, you’ll see them on the left-hand side.

   3. Click the file you want to view, then click preview.

   4. The sEMG signal will appear in the middle of the screen.

3. Decompose your Data

   2. Click Process to decompose files.

   3. Choose the location where you want to save your data.

   4. It can take 1-2 minutes for the decomposition process to start after clicking Process.

   5. Each Trigno Galileo sensor will get its own progress bar, and decomposition only happens for one sensor at a time.

   6. Once decomposition is complete, a new .DHPF file will be created. This data can be analyzed using NeuroMap Explorer and then exported for further processing.

Information

• The decomposition progress bar will not update until the file is decomposed, as long as the loading symbol on the left hand side is moving, the decomposition process is underway.

• Motor unit decomposition takes approximately 1 minute per second of data for each sensor (i.e. a 30-second trial may take ~30 minutes to decompose from a single sensor).
