Save Digital Data to a Text File

I have digital data collected from two ports simultaneously as N number of samples in waveform that I do calculations on to get a result. I would like to save the raw data in a text file so that it can be easily viewed in an external program, like Excel.  This file would be used as verification of the result calculated in my program. I would think this would be a simple thing to do in labview but as yet have not figured it out. I’ve tried to change the digital to analog and then save as a text file but the data no longer gives the same results when recalculated in an external program. Thanks for any input on this subject.

I am using 8.20. 
Thanks, Tessa

  • How do I save a mutlitcolumn data to a text file?

    I am trying to save a multicolumn data to a text file without using Report Generation VIs. Here is the detail scenario...
    I have data in the following format.
    Time Voltage
    1 2
    2 3
    3 6 ...
    and
    Power
    1
    and
    Peaks
    x-axis y-axis
    Peak1 1 4
    Peak2 5 11
    If I have such data, how would I put them in a columnar format with their title and labels in a text file.
    Any example VIs would be nice to see.
    Thanks.

    Here is one solution, hope it helps. I would like to see this done using clusters and less shift arrays, I'm sure there are a few ways to do this with less wires but i guess that's what sub vi's are for...

  • How do you read data from a text file into a JTextArea?

    I'm working on a blogging program and I need to add data from a text file named messages.txt into a JTextArea named messages. How do I go about doing this?

    Student_Coder wrote:
    1) Read the file messages.txt into a String
    2) Initialize messages with the String as the textSwing text components are designed to use Unix-style linefeeds (\n) as line separators. If the text file happens to use a different style, like DOS's carriage-return+linefeed (\r\n), it needs to be converted. The read() method does that, and it saves the info about the line separator style in the Document so the write() method can re-convert it.

  • How to do import data from the text file into the mathscript window?

    Could anyone tell me how to do import data from text file into mathscript window for labview 8?
    MathScript Window openned, File, Load Data - it has options: custom pattern (*.mlv) or all files. 
    Thanks

    Hi Milan,
    Prior to loading data in Mathscript Window , you have to save the data from the Mathscript window (the default extension of the file is .mlv but you can choose any extension). This means that you cannot load data from a text file  that was not created using the Mathscript window.
    Please let me know if you have any further questions regarding this issue.

    Hi there,
    Here is an example of reading a String and a date from a text file. Once you have what you need in the Strings (or whatever) it should be easy to insert them into and SQL statement. Let me know if you need an example of this as well and I'll post it in the morning. Right now I'm off to bed :o)

  • Write Text Data Array to text file

    Greetings all. I hope someone can help me as I am really under the gun. The attached vi shows the basics of what I am trying to do. I have already written a vi that takes the Cal Data Array and prints it out in a nicely formatted report. My problem is that the powers that be also want the data saved to a generic text file that can be copied and printed out anywhere they like. As such, I need to save the data to a generic text file in column format such that it will all fit on one page in landscape mode. There are a total of 12 columns of data. I have been trying to create something that would format each column to a specific length instead of them all being the same. No luck so far. Basically, I need columns 1,2,3,8 and 12 to be length of 5. The rest a length of 9. I have tried to place the formatting part in a for loop with the formatting in a case, but it does not appear to work. I really need this quick so if anyone has any ideas, please help. As always, I really appreciate the assistance.
    Thanks,
    Frank

  • 1 Analog Input using a DAQ card and would like to save the data into an excel file

    As you may have realized, I am very new at using Labview 6.1. I have an analog voltage input that I would like to save in an Excel file as a 2D array (time, voltage). I was wondering if anyone knew a very simple way of doing this and could help me out. Thanks

    There are a couple example program online and in LabVIEW that I think you’ll find useful. You might want to consider just writing out a tab-delimited spreadsheet file that Excel can read rather than writing it out to Excel directly as this requires learning ActiveX and Microsoft’s Common Object Model.
    In LabVIEW, see the Write to Text File.vi in C:\Program Files\National Instruments\LabVIEW 7.1\examples\file\smplfile.llb. Writes simulated, timestamped data to a text file in ASCII format that can be read by spreadsheet applications.
    Online, you can look at:
    Stream Scaled Data (Voltages) to a Spreadsheet File
    Chart Analog Data from File, Using the Cont Acq to Spreadsheet.vi Example
    Hope this helps. Best of luck!

    HI Martin,
    i am not realy sure what you want!?!?
    i think you want to display only a part of the values you read from XYZ
    so what you can do:
    write all the values in an array.
    the size of the array is the max. value of the slide bar
    now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
    the other option is to use the history function of the graphes

  • How to extract  different date format in text file

    well, iam new for using regex api(regular expression), In my project i want to extract the different format of date from the text file... date format will be 3rd june 2004, 03-06-2004, june 3rd and so on....
    can any body give me regular expression to extract the date from the text file...
    i will be very grateful..
    kareem

    date format will be 3rd june 2004, 03-06-2004, june 3rd and so on....The only way to do this (without implementing a "mind reader") is to determine in advance all the possible date formats that are possible in your input, and try to interpret each date using each of those formats until one of them passes.
    It's easy enough to handle june 3rd vs 3 june vs 3rd june, but 6/3 vs 3/6, of course, is ambiguous.

  • How to automate loading data from a text file ?

    Hi,
    I need to load a data form a text file automatically. (for example: every day at 6.p.m) .
    It is possible to use DBMS_SCHEDULER with SQL LOADER ? or maybe u have others idea ?
    regards,

    assuming that the text file resides at the machine where the database is installed at you can create a procedure that use the built-in UTL_FILE package to read and load the data to the oracle tables. then create a job that use the DBMS_JOB or DBMS_SCHEDULER to create an automated schedule to run the job that calls the procedure you have created.
    or assuming that the text file resides or at the local/client machine (example c:\ drive) on a windows xp platform. create a batch file that do a ftp to transfer the text file to the oracle database server and create a schedule job using the windows scheduler. also create a procedure that use the built-in UTL_FILE package to read and load the data to the oracle tables. then create a job that use the DBMS_JOB or DBMS_SCHEDULER to create an automated schedule to run the job that calls the procedure you have created.

  • How to parse data from a text file with no convenient delimiters?

    I need to read data from a text file.  This file contains one line of data with the repeating pattern "time 00 ADVar2: ___ Height: ____ time 01 ADVar2: ___ Height: ___ ..."  I need LabView to parse out the "time" and "height" values, build an array with the values, and graph the correlation on an X&Y plot.  Does Labview have an automated way to read to the input data file and parse out the correct values, even without convenient delimiters?  Thank you.

    You actually do have a convenient delimiter: "time". Thus, you can make an array using that as the delimiter. Only caveat is that the first array element will be empty. Then you can conveniently use the Scan From String function in a for-loop. Something like this:

  • Write data to multiple text files after specific size

    Hello,
    I wrote a code that contineously writes data to  a text file. The problem is I am running this VI for long time and therefore this text file is being bigger in size e.g. more than 10MB. I want to split writing data in this text file after max 1MB size. Can anyone help ????
    thanks in advance.

    You could use the "File/Directory Info Function" in the Advanced File VIs and Function palette to check the size. If the file is too big. close it and create a new one.
    I would use the Get File Position since this won't cause Windows to have to do so much.  Assuming you are just writing and not setting the file position manually, this will return the size of the file in bytes (file position will always be at the end of the file).

  • Read data from a text file, one line at a time.

    I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.

    The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
    The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
    If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
    m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
    Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.
