How to open an lvm file in MATLAB Script Node

Question

Hello everyone
I am using LabVIEW 8.0 in order to acquire a signal, and I chose to save the signal's data with "Write to Measurement File"
Here is the problem, later on I am using a MATLAB script on the data, but the problem is that the MATLAB can't read the lvm file, because it doesn't have a txt ending.
So my question is this : is there any way I can convert in LabVIEw the lvm file to txt ???
Thanks ,
Lavi

Answer 1

Edit: Sorry about the double answer on the .lvm file. Posted at the same time as previous answer.
The .lvm file is a text-based file. Form the online help for LabVIEW :
Use text-based measurement files (.lvm) to save
data that the Write To
Measurement File Express VI generates. The text-based measurement
file is a tab-delimited text file you can open with a spreadsheet application or
a text-editing application. In addition to the data an Express VI generates, the
.lvm file includes header information about the
data, such as the date and time the data was generated. LabVIEW saves data with
up to six digits of precision in a .lvm file. Use
binary measurement files
(.tdm) to exchange data with higher precision.
A few comments regarding your code:
Learn to stop using sequence frames. This is typical for someone coming from a text-based language programming environment. This is not a personal knock on you, just a pointer. For example, instead of using the "Wait (ms)" function you can use the "Time Delay" VI. That has error in/error out clusters which will allow you to chain VIs. In the bottom part you can eliminate the sequence frame that you're using the parallel port write to the following:
which is much cleaner and easier to read.
The loop where you're reading data is pointless. It is set up to run only once, so what's the purpose of a loop?
You do not need to place all objects inside a sequence frame and then place the sequence frame inside the loop. This is redundant.
