Our first case

We will go through one of the examples step by step

  • Download the Standard examples above and unzip them somewhere on your computer
  • Start DGM
  • Click Select File and browse to where you unzipped the examples and
    go to example E_CARTO_reg_reentry
  • Select CARTO_260ms_car.txt and press open
  • Enter 260 in the Cycle Lenght field and press enter
    You will now see a first rendering of the mesh and measured nodes
  • Under Settings > User key enter the key you have received. Save & close
  • Press Calculate. Depending on the data this will take from a few seconds to a minute
    When done, the found loops are displayed on the 3D mesh as shown in the image below

You can now try the other examples yourself, or process your own data.

Other examples

Please check the table below to see which input files correspond to which cycle length and time interval. After setting the cycle length, DGM will automatically use the correct time interval.

For irregular data, a cycle length of -1 should be set

Input fileCycle length
A. Regular reentry 3DLAT_p2000.txt213
B. Regular focal 2DLAT_p529.txt500
C. Irregular reentry 2DLAT_p900.txt-1
D. Irregular focal 3DLAT_p2000.txt-1

E. Regular reentry CARTODGM_260ms_car.txt260
F. Regular focal CARTODGM_290ms_car.txt290
openCarp simulation
G. openCarp 3D irregular reentryvm.igb-1
H. openCarp 2D irregular reentryvm.igb-1

Example output

How to export clinical cases

Currently a parser is present to automatically convert both CARTO (_car.txt) and RHYTHMIA (.mat) files to the correct DGM input LAT_p{nodes}.txt file. We plan to add support for the Ensite mapping system in the future as well.


DGM has been tested with CARTO version V7.1.80.33

Load Study and export Study data
  • Go to start screen of CARTO
  • Click Review Study and select the Study from the case you want to export
  • Now you can make movies and gures which will be also exported to your external hard drive
  • Click Study (top left) > Export Study Data
  • Make sure 'Base' and 'CARTO VISITAG Module' is ticked on
  • Now a pop up appears: 'Create File in progress'. This may take a while depending on how many points the study contains
  • When this pop up disappears, you exit the study by clicking Study > Exit
Export Study data to external hard drive
  • Go to start screen of CARTO
  • Go to System > Export Data ...
  • Go to the case and select the 'Export' and put it in the queue
  • Enter a password and confi rm it (top right)
  • Select the the folder in which you want to save the export data on your external hard drive and click export
  • Now the export is saved on your external hard drive
Decompress export

Finally we need to decompress the files on our own computer. Popular tools to do so are 7zip and winrar. After decrompressing to your preferred folder, you will see a lot of files appear. The ones needed for DGM are the files ending with .mesh and _car.txt.

If present, Ablation file is typically found under VisiTagExport/Sites.txt and PPI in an xml file named Study ....

You are now ready to analyze your own CARTO data with DGM! See examples 5 and 6 for more info.


To export your RHYTHMIA case you need to select Export as > MATLAB - Map Data Basic which is available for systems running SW 3 (Lumipoint), SW 4 (Autotag) and later.
