Hi phrost,

I may need some more information in order to assist you. Are you using any NI hardware to capture the data? What format is the data saved in? Have you already tried to display it on LabVIEW and if so, could you possibly attach a copy of the VI you have been using?

Regards

Jeremy

Thanks guys for the reply, I'm using the NI-DAQ device, not sure what its called, its a small little white box. Attached is the VI for my project.

Thanks again

Hi just to update i'm currently not using the DAQ card, I'm now using the NI elvis, so can anyone help me please?

Thanks

Hi,

Thanks for attaching your VI. In order to assist you further, it would be useful to know whether you are using Elvis I or Elvis II, as this will decide the best course of action from this point on.

NI Elvis I 

NI Elvis II 

Please could you reply back once you know which one you are using? Look forward to hearing back from you,

Regards

Hi Jeremy,

Thanks for your help, I'm currently using NI Elvis I, and using labview 8.2. Thanks again.

Hi,

I noticed in your VI that you are using DAQ Assistant Express VIs in conjunction with Elvis I. Is this producing any errors when you try to run the VI? If so, could you give me any details of the errors? I'll be interested to hear if they are running smoothly together.

Also, going back to your original post, you mentioned that you had captured the ECG signals. Was this also using Elvis I? And by 'captured', do you mean that you saved the signals to disk, or that you were able to view them, on an oscilloscope for example? And if you were able to save the images, could you tell me what format please?

Hi jeremy

there is no problems running the VI now, but i need to make some modification to this VI such that it can process ECG readings. The ECG machine would be hooked up to ELVIS I and from there the "live" readings would have to be processed by the modified VI, but I don't really know how to modify it. Please advice asap. Thanks
