Reading from a multi-segment measurement file

[rayt]

Hello!

I am writing a save/load section for a Labview program.  I write a few scalar parameters in the first segment of a measurement fil, then I write a few arrays of data. While loading, normally I want to read the  pareameters first, and then read the data arrays.

The text file has correctly two segemnets with the data. However, when rading the lvm file, it reads the first segment again in the second reading. I have played with Reset options but I could not fix it. I have attached a word file with both save and load block diagrams. Am I doing this right?

Also a second issue is that I want to save two-dimensional arrays, but when it reads the file, each column is separated in the output signals.

Thank you,

Hi Reza,

I have been able to reproduce what you are seeing.  I am looking into this further and will let you know what I find out.  Thanks for your question!

Hi rayt,

can you upload the pictures directly instead of hiding them in some proprietary file formats?

Here you go...

Hi rayt,

I see only locals and express vis -I will stay away from this

Do you mean that somebody else will look into this problem?

Hi Reza,

I believe this to be a bug and have reported it to R&D.  However, for a workaround, do not include headers in your LVM file or use TDMS file type instead.

Thank you Kristen. I tried binary tdms type as well, the same problem happens there (reading the first segment again). It may be helpful to know that TDMS fileviewer shows that the file has been save correctly.

Hi Reza, 

I was able to plot both signals when I configured my TDMS file to have only one header.  I'm guessing the one header per section issue is related to the LVM header issue.  I will file another bug report to get that corrected.  Sorry about the inconvenience.
