Read Text row by row, plot them and find the max of its Power spectrum

Hi, everyone,
I have to read data from a text file, plot as a time serie and find the frequency to its max power spectrum. I found a previous post related to my issue so I revised his example a little bit. But once I decide to store the data into an array, the Labview reported:' Error 1 occurred at Scan From String (arg 1)'. Can anyone help me out?
Thanks in Advance!

  • How do I read text from specific rows and columns in a tree structure?

    How do I read text from specific rows and columns in a tree structure? In a table you can specify the cell to read from but I have not been able to figure out how to do this with a tree structure.

    You need to set two properties to activate the correct cell and then you can read it's string property.
    The positioning properties are the "ActiveItemTag" and
    "ActiveColNum" properties. With them you select the tree item by it's tag and the active column. The string can then be read from the "Cell String" property.

  • Problem with reading text from .DOC files through java and POI

    I have used a jar file "poi-scratchpad-3.2-FINAL-20081019.jar" and "poi-3.2-FINAL.jar" to read text from a .DOC file. I used the "getParagraphText()" function of the class "org.apache.poi.hwpf.extractor.WordExtractor" to get the text.
    I am able to get the text in the .DOC file but along with that i am getting the following messages/warnings

    Below the above messages/warnings the data is getting printed. Only the text part of the data is retrieved not the fonts, styles and bullets etc.
    Can anyone explain me why I am getting above warnings and how can I remove them. Is it possible to fetch the text depending on delimiters.
    Thanks in advance,

    The jar files which were used are downloaded from http://jarfinder.com. Those jars created the problem of displaying those messages on console. I downloaded APIs from apache.org and used them in my application. Now my application is running good.

  • How can I synchronize my iPhoto events? my iTunes doesn't read them and with the app Images in the iPad I can only find Photos, Albums, Faces and Places, not Events.

    How can I synchronize my iPhoto events? my iTunes doesn't read them and with the app Images in the iPad I can only find Photos, Albums, Faces and Places, not Events.

    I had a problem a couple of months ago when iPhotos suddenly rearranged the order of my Events (Why won't iPhoto let me arrange my photos?) .  I was told "Use albums not events - events are not a good way to organize - albums and folder are designed for organisation and are very flexible".
    Haha!  I should have paid attention and read between the lines!  My iPhotos were highly organised groupings - not according to date but the way I wanted them - and it was so easy to do!  I see now that if I had them all in albums, as per the Apple Apologist suggestion, I wouldn't have this unholy mess I have been left with just to make iPhone & iCloud users happy.  I am now going through Photos and making Albums (of what used to be in my Events)  ... maybe I'll get this finished before they do another non user friendly update!

  • When I access my google e-mail account on the I-pad my inbox has at least 6 e-mails with no sender and no subject (absent via I-phone, Mac or PC) I cannot delete them as they cannot be selected- how do I stop them and clear the ones there now?

    When I access my google e-mail account on the I-pad my inbox has at least 6 e-mails with no sender and no subject (absent via I-phone, Mac or PC) I cannot delete them as they cannot be selected- how do I stop them and clear the ones there now?

    Try turning the account off and on : Settings > Mail, Contacts, Calendars , then tap the account on the right, slide Mail to 'off', exit settings and go back into the Mail app, and then go back to Settings and slide Mail back to 'on'
    If that doesn't work then try closing the Mail app completely : from the home screen (i.e. not with the Mail app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    Also do a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • How can I read text files from LAN if I only know the hostname?

    I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
    <p>1. How can I read text files from LAN if I only know the hostname, or IP address?
    <p>2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.
    (ex. how can I read the 120th line?)
    <p>Please help!
    <p>sorry for the bad english

    I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
    1. How can I read text files from LAN if I only know the hostname, or IP address?You need to know the URL of the file. You need to know the hostname, port, protocl and relative path.
    The hostname is server, not file.
    2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.Use the seek() to get to a random byte.
    (ex. how can I read the 120th line?)The only way to find the 120th line is to read the first 120 lines. You can use other file formats to find the 120th line without reading the whole file but to need to be able to detremine where the 120th line is

  • HT5699 I forgot the answers for security questions, how can I reset them and get the access back to the iTunes store?

    Need help to get access to iTunes store. I bought an iTunes card bor buying on iTunes store.
    I forgot the answers for security questions, how can I reset them and get the access back to the iTunes store?

    If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then go to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you should see an option to send security question reset info to your rescue email address.
    If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then you won't get the reset option - you will need to contact iTunes Support or Apple to get them reset.
    e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then 'Forgotten Apple ID security questions'
    or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
    When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down this page to add a rescue email address for potential future use : http://support.apple.com/kb/HT5312 . Or you could change to 2-step verification : http://support.apple.com/kb/HT5570

    What do you mean "Leave them my laptop again"? do you mean you have had it worked on before? for the same problem or a different one?
    You need to take it in to Apple ASAP. No matter how long they have it, you want it fixed and fixed correctly.
