Unable to read Labview Txt File in Matlab

[sagar.vidhyam@yahoo.com]

Hi,

I have generated a text file in labview with file I/O's. when i am trying to read it in matlab 

the matlab is showing an error as 

??? Error using ==> dlmread at 145
Mismatch between file and format string.
Trouble reading number from file (row 1, field 1) ==> …Eôþô

Thanks.

It doesn't seem to be a normal text file, it involves some sort of formatting. Can you show the File write function that you have made?

Hi,

You created a Binary file, not a Text file.

Hi,

This is not a binary file. I performed a real time demodulation(communication), converted the binary bits to ascii string characters and saved in a text file.

Okay,  I have created a simple text file in labview and i tried to read in the matlab. the same error occurs.

dlmread('Test.txt');
??? Error using ==> dlmread at 145
Mismatch between file and format string.
Trouble reading number from file (row 1, field 1) ==> kjfhe

what i found is that the labview saves in ASCII text but not in plain text.

Also  I created a tab delimited Text file. the same error follows

??? Error using ==> dlmread at 145
Mismatch between file and format string.
Trouble reading number from file (row 1, field 2) ==> :10:2

Then your bits-to-ASCII conversion was wrong. Open Testfile1.txt and have a look: that's not an ASCII file.

Please post your code. We can't help you otherwise.

What do you mean? ASCII text is plain text!

That's not LabVIEW's problem.

MATLAB's dlmread only accepts numbers -- it won't accept timestamps like "4:10:27 PM" or alphabetic strings like "kjfhefghk..." (please see MATLAB's documentation)
