Data import from Biosense Webster Carto3

1

Hi,

I am trying to get started with OpenEP
and import electroanatomical maps
from Biosense Webster Carto3,
namely the list of points with
spatial information and obtained curves.

I can obtain Carto-data in different ways
from the machine, but am unsure, which one would be the
right one i.e. which file types I can load in OpenEP and how.

Could you kindly give me some hints to get me started?

Best, Matthias

Hi Matthias

Thanks for your message.

You will need to work with the exported study data. To access this, load up the case and choose Study > Export Study Data. In there, choose ‘base’ plus any other data you want for example Visitag data.

The system will take perhaps 10mins on average to create a zip file.

Next, exit the case, and from the main menu choose System and Export (from memory!).

This will allow you to select the new zip file and copy it across to your USB drive

Finally, on your computer with OpenEP installed, unzip the file, run the function importcarto_mem() and navigate to the study XML file which is usually named something like Studyxyz.xml

And of course, so let us know how you get on!

I keep getting this error when trying to import carto data. Please help

Brace indexing is not supported for variables of this type.

Error in importcarto_mem (line 502)
kEcg(i) = find(strstartcmpi(channelECG_cli{i}, namesTemp));

Error in importIVY (line 1)
userdata = importcarto_mem ();

Hi Lydia, most likely this is a problem with electrode naming. We can debug this and get it working; however we will likely need some information for you to do this.

In the meantime, it might be worth trying the very latest development branch - this is feature/newfilestructure

Please could you try to import your data with that and let us know how you get on?

The new files worked. Thanks
