Problems reading waveform files in MATLAB

[Tomaz Lusin]

Deal all,

I acquired signals on 2 A/D channel (using DAQ board M USB-6215) and save them into waveform file using WriteWaveformsFile.vi. But for processing (FFT, elippse fitting, sinewave fitting) I want to use these data in MATLAB. I tried some options like conwert waveform to bin file but I cannot get these data in MATLAB correctly. I also convert waveform data (or data from one waveform) using WriteToSpreadsheetFile.vi, but still I can get correctly data in MATLAB. I am not sure what I'm doing wrong. Thank you for you help on any tip. I use matlab R2009a andLabview 8.5.

Tomaz.

hi,

 While saving the data in a file,please use the write to measurement file(express VI) and configure for *.lvm ,without header and time column.So since this *.lvm file is a normal text like file,try to read it in matlab.

Thanks and regards,

Hello, I have waveform file saved and I want use these data to be read in MATLAB. I have problems to correctly save these data to file (e.g. .bin or .xls) to be available in MATLAB. I will try save data from waveform file to measurement file as you suggested. I hope this wil help. Thank you for the tip, srikrishaN.
