LabVIEW acquisition Binary data and the compatibility with Igor software

[Justin_Liu]

Hello everyone,

We use LabVIEW as our data acquisition software, but all the analysis is done with IGOR. Since some of the measurements take some time it would be nice if the already acquired data could be transferred to IGOR can readable binary, now We can write the data as a excel format, but it is limited memory using excel, so we have to save as a binary format, but labVIEW binary could not read using Igor. 

Does anyone know any way how to do this communication between LabView and Igor?

Thanks a lot for any ideas!

From what I found in a 30 second Google search, you can define the format in IGOR however you need to.  What format are you set up to do?  How are you logging the data in LabVIEW?

Dear  crossrulz,

Thanks for your fast response!! 

I used the “write to measurement file”, now set write as a excel file, but I tried using binary (TDMS) or TDM, both couldn't read with IGOR.

Try using the Export Waveform To Spreadsheet File instead.  By default, this will write your data to a tab delimited text file.

Dear  crossrulz,

if using the Export Waveform To Spreadsheet File instead.  By default, the memory can acquire long time data ?

For logging over more than s few minutes, I highly recommend using a Producer/Consumer.  The idea is to log the data in parallel with the acquisition.  Use a queue to pass the data from the aquisition look to the logging loop.
