Big waveform to text

Hi,
I have to append waveform arrays to a single waveform then convert them to text file. 
There are 8M lines (rows) X 60 column of character (maximum).
Then, I m facing "not enough memory" problem, and I think I have to save the waveform to binary files. But for viewing purpose, I still have to convert them to text file. 
Any idea to view big waveform ? 
Here I attached the VI and waveform which saved in binary format. Please advise. Thanks.

Is there a reason to use text vs binary?  I usually switch to binary at about 10,000 points.  That said, the advice you were given above is good.  You can't do it all in one step.  You have to break it up. I have one more tip for you.  If you save your data so each text field is always exactly the same width (it can be padded with spaces), it is trivial to seek to a specific line by calculating the offset from the beginning of the file.  With variable length fields, you need some sort of indexing.  At that point, you should probably use binary (try TDMS or NI-HWS).

  • Big and small text alignment

    Why doesn't InDesign align text to the border of the textframe?
    Especially with big and small text in the same textframe, the gaps before the text are scaled too making text optically not aligned at all.
    Optical margin alignment helps a bit, but not good enough.
    Am i overlooking something?
    Still working in CS3 btw.

    Ok knowing the right term "side bearing", i did some google searching and stumbled upon this topic at indesignsecrets:
    http://indesignsecrets.com/removing-space-along-left-edge.php
    There's a link to a script from Dave Saunders that aligns the letters optically to the left. Tested and works! InDesigns own optical margin alignment should be turned of though. I immediately assigned a shortcut to this great script.
    PS: Concerning the "why is side bearing split into left and right": i guess for example a letter 'D' for example shouldn't have equal side bearings because of the rounding to right.

  • Prevent Text Boxes to shrink as big as the text in it - move existing InfoPath form from SharePoint 2007 to SP2013

    Hello Together,
    we have some simple InfoPath forms in place. With SharePint 2007 they are working well. Now we will move to SharePoint 2013.
    It was easy to re-publish them on a SharePoint 2013 Site and to work with, but i have an optical / technical error and i don't find the solution.
    We use Text Boxes to collect the data from the user. After the user has filled the form we will submit them via mail.
    I will you show you the problem.
    on SharePoint 2007 --> it looks okay
    on SharePoint 2013 --> not okay - the Text Box is shrinked to the text Size and the design is defect
    How can i prevent this?
    Thanks in advance
    Sebastian
    I can provide Screenshots, bit at the moment my account is not verfied...

    Can you please share screen shot.
     Before try removing the field form View and  Add it again - check it

    If you have nvidia video and are using the nvidia driver then add the following to the Device section of /etc/X11/xorg.conf (if you have one) and restart X:
    Option "UseEdidDpi" "False"
    Option "DPI" "96 x 96"
    If you are using gnome then select System -> Preferences -> Appearance, click on the Fonts tab, click on Details... and check that the resolution is also set to 96 dots per inch.  While you are there, set smoothing to subpixel and hinting to full, or pick whatever other setting looks best.
    Edit: Oh, and make sure that you have the ttf-ms-fonts package installed.

  • Site renders about 20% too big in IE - text and graphics

    I used an Adobe template, then customized it, which is
    probably the problem!
    Web site is:

    CSS is located at:
    http://www.lmrfd.org/css/lmrfd.css
    Looks fine in Firefox, but IE blows everything up about 120%,
    making the graphics look bad. I can't figure out what I've done
    wrong. Any help or advice is appreciated!
    Thanks,

    Hello,
    They look the same to me in IE7 and FF.
    If using IE7, does it say 100% in the bottom right corner of
    the browser?
    Take care,

  • How can I disable Notification Centre in IOS5 and go back to getting the big blue text message notifications?

    I have Iphone 4S on iOS 5
    I flicked the button in settings to set up Notification Centre, but now I want to disable Notification Centre as the text notification is nowhere near as good as the old 'big blue' text received box.
    1- where do I find button to DISABLE Notification Centre? (I can't find one)
    2- how do I revert back to the old big blue box text notification?
    Thanks

    I've tried literally every option available in "Notifications" to get back the big blue box, but it seems that every option I choose nothing really changes.
    The messages continue to come up with the small box, green Message icon, and the name and Text Message beneath.
    Is there no other way, or some sort of trick, to get the blue box back?
    Thanks!

  • Unable to send a text

    I just got an iphone 4 and I added my friends in contacts. When I try to text them, I do not get the delivered message and they are not getting the text. But if they text me first then I am able to send a message and have them receive it..
    How do you fix this?

    big difference between Text and iMessage. Please elaborate.

  • Combining Text in Automator for Excel import.

    I'm attempting to create an automator workflow that will string some text together so that it can be imported into an Excel worksheet. Here's my workflow so far.
    • New Text File
    Creates file temp.txt
    • Run AppleScript
    Opens file temp.txt
    • Get Specified Text (specified text below)
    Read Today
    Read Tomorrow
    Read This Week
    Read This Month
    • Filter Paragraphs (needed so the text is not treated as one big line of text and is displayed in the next step correctly)
    Return Paragraphs that are not empty
    • Choose from List (all 4 items displayed correctly, all selected by default)
    Select one item
    • Set Contents of TextEdit Document (temp.txt) (append)
    • Get Specified Text (specified text below (a semi-colon))
    • Set Contents of TextEdit Document (temp.txt) (append)
    • Get Specified Text (specified text below)
    keywords go here
    • Set Contents of TextEdit Document (temp.txt) (append)
    • Get Contents of TextEdit Document (results below)
    Read Today
    keywords go here"
    (Once I get this part working, I will add a URL onto it also).
    So, all my content has arrived here, but on three different lines. But because it is on three different lines, it does not import into Excel correctly. I can't concatenate this using the usual AppleScript method because I would have to declare these items as variables. I've tried various ideas, but I cannot get the three above to append to one line, like this…
    Read Today;keywords go here
    without manual intervention, which sort of defeats the reason for trying to automate this.
    I hope I've explained this well enough that it makes sense.
    Any help or ideas are appreciated.

    Well, it is good to know that it can be done in Applescript, though I have not found a way to accomplish this. All examples I have seen (Googling and AppleScript 1-2-3 book) use set statements using static strings, and then concatenating those statements together. Since my values are dynamic, those examples don't help.
    What I have to work with are these lines of text in a new document.
    Read Today
    keywords go here
    The text will vary from run to run.
    What I need to end with is… (for use in Excel, import text files action)
    Read Today;keywords go here (line1 & line2 & line3)
    So, I don't know how to proceed from here, unless I can do something like set var1 to line1 of temp.txt, set var2 to line2 of temp.txt, etc.

  • The waveform of output from file is different from original one

    I've a new question about displaying a waveform from a text file. The waveform which its data is from file is different from the original one.
    I attached image files which included my two vi files and 3 waveform. In the compressed file, "ReadData_Waveform1.jpg" is a image of waveform from "ReadData.jpg" vi file with the configuration of "Transpose" is True,
    "ReadData_Waveform2.jpg" is a image of waveform from "ReadData.jpg" vi file with the configuration of "Transpose" is False,
    "WriteData_Waveform.jpg" is a image of waveform from "WriteData.jpg" vi file.
    I attached the source file of waveform with text format as well.
    Please help me to solve this question if there is anyone who can figure it out.
    Thanks, Andy.

    Hi Andy
    If you transpose the data when you write it, you also have to transpose it when you read it.
    Just have a look at the simple example attached. I write data and read it again. Each file operation is called with the default-value for transpose (false). The data is read correctly.
    Hope this helps.

  • How to calculate the size of a Text Field?

    Is there a way to calculate the number of characters allow in a Text Field? If a uer type over this number of characters a popup window will appear telling the user that he/she has too much texts. Of course I could use the Limit Length, but I have to manually put texts into this text field and count them. If the Limit Lenth number is too small, the texts does not fill the whole text field. If the number is too big then the texts does not get printed.

    There would be no easy way to do this. You'd need to do some pretty fancy calculations, it would all depend on the size of the field, what font is used, the font size, whether it's been bolded, underlined, italicized, etc etc.
    What are you trying to accomplish? Make it so that the user can type in the text field until it fills and then have it stop without scroll bars coming up to allow him to keep typing?

  • How can i edit text on a pdf document on acrobat i professional

    can anyone please help me, I've got acrobat 8 professional and i'm trying to edit text, can i do it and how can I do it?

    You wrote: I have tried creating the background image as a pdf . . .
    The whole thing is already a PDF.
    What application are you using to try and make changes?
    Are you now using InDesign to recreate the gift voucher?
    Or are you opening the Photoshop PDF and trying to resize the live text layers?
    There shouldn't be any issue with making 120 pt text. I just created a 250 pt text layer in PS as a test.
    Have you enlarged the text box? If the text box isn't that big. making the text larger make cause it to overset and no longer be visible.
    Grab the corner of the text box and drag it to enlarge it.
    If things aren't working correctly, it would be faster to recreate the gift voucher in InDesign.
    You mentioned having the background image, just add the text are you are ready to print.
    After rereading your last post it is unclear who will be adding the text for the money amount.
    Are you adding this yourself before printing, or are you hoping to give a PDF to the client where he can add/change the money amount?
    Things like this need to be mentioned upfront.

  • How to create text names within a number or shape

    I would like to learn how to create a print design for college hoodies. I get asked all the time but it takes me a very long time to do it. I am sure there is a quicker way in illustrator.
    I want to create a design like this image. Can Anyone Help me please?
    I am using Illustrator CS 5.1 right now.

    Just use the big numerals as text boxes and pour text into them.
    Be aware thought that text boxes can not be compound paths so you will have to make some special arrangements for 4, 6, 8, 9 and 0.
    Either Text Wrap or slice the numerals into smaller abutting text boxes. I suggest that the latter will be easier.
    Once you’ve done the job the first time it will be easy to do a repaet with new text.

  • Text area submits

    I created a form that submits articles. Articles consist of
    paragraphs. Every time I insert a article into a database, I lose
    those paragraphs so when its posted on the website, its just one
    big blob of text. How can I keep my paragraphs when I submit a
    article. Also, when I click in the text area, I can pretty much
    click anywhere in the text area. How do I make it where the Cursor
    starts to blink at the very top left of the text area.

    I lose those paragraphs so when its posted on the website,
    its just one
    big blob of text.
    The paragraphs were not lost, you are dealing with different
    systems
    that handle paragraphs in different ways.
    In plain text, paragraphs are ended with some kind of
    carriage return
    and|or line feed. In windows systems this is almost always
    the ASCII
    characters (13) carriage return and (10) line feed.
    HTML does not recognize these carriage returns and line feeds
    and
    ignores them. So they where there in the output, but being
    ignored by
    the browser. What CJ's function is doing is converting the
    ASCII
    characters into the HTML <br> tag that the browser
    understands. The
    CHR() function is for working with ASCII characters by their
    code numbers.
