Help, please! Memory increases with Scripture PDM

Hello guys,.
I use a TDMS file to store the data of 16 accelerometers sampled 10KS/dry, you can therefore imagine the size of the files are going to be huge (more than 10 GB for 2 h or more registration).
I want to be able to save a subset of the PDM file, or even the complete file to another file PDM. I'll have no problem writing in the file when you read of accelerometers.

When trying to read the TDMS file and write a new, I'll have a lot of memory problems, so I read pieces of 5000 samples within a certain time the strand and then writing to the file.
I have included the code.

the code is attached. Please help as I was stuck with this memory problem for more than a week now!

Kind regards
Simon

I don't think that opening and closing of the case will make a difference.
Have you defragged the original TDMS file?
And I think that you can read in segments of 10 MB without problem.
Why you put away the time anyway, your waveform will be information in real-time.

  • Help please using templates with css files

    Hi, can someone help me with this conundrum?

    I have a site page 5, based on a common model with the BODY tag as an editable for other pages. However these pages require a separate CSS file, but I can't find a way to change the files for different pages.

    The model that I created (Home.dwt) contains its own CSS file, but how then modify this file based on other pages?

    Any help would be appreciated

    Any help would be appreciated

    Take a look in your Home.dwt file to the top, between thesection. I think that when a model is saved/created by Dreamweaver inserts an editable 'head '.

    If its in the file Home.dwt, then it should be in all the other pages created from the template. Simply insert your css like below:

    Insert here the CSS

    If it is not in your file already Home.dwt to create an editable region for the specific css of the page:

    Save the Home.dwt file, and this region is expected to propagate to pages from the model

    Also please take into account the fact that any new styles css for a particular page should go in the code AFTER the link to your existing css file. This ensures that the new css styles will too drive css styles in your linked css file.

  • Help, please! Problem with QuickTime audio recording of the iPod?

    Before you start: I one day 32 GB 6th gen (newest) iPod Touch and uses a MacBook Pro with OS X Yosemite 10.10.5 early 2015. QuickTime Player is Version 10.4 (833.7).

    I have an iOS game and you want to record a video of my game using QuickTime. I want to record is just two things: the screen of my iPod (to show the gameplay of course) and iPod audio (to listen to the music of the gameplay, sound effects, etc.). I play with headphones plugged into my iPod, so, naturally, I want to listen to the game and have the video recording, the audio of game as well.

    Unfortunately, a problem arises however. I insert my iPod in my computer, ready to start game and the headphones plugged into the iPod. I open QuickTime, then click on "file > new Movie Recording. From the drop-down list next to the button REC / I click on "camera > iPod of [my] Touch" and "micro >" of [my] iPod Touch '.» Immediately I can't hear my headphones... ! However the emulation screen iPod appears perfectly on my MacBook.

    If I press the record button when even just to see what happens. I recorded about 20 seconds of the game and click on stop. Pretty funny his returned to my headphones right when I stopped recording! Nevertheless, I plugged my iPod headphones on my MacBook and played the video I just recorded. The 20-second video has audio PERFECT, everything in the video went extremely smooth and no audio/visual of all issues.

    I wanted to keep trying, then instead of having already my headphones for my iPod, I tried to open QuickTime with my headphones unplugged; and then plugged my iPod after QT has been opened. The emulation screen FROZEN unlock and then when I unplugged the headphones. Unplug and plug in any again gave the same results. I waited a few minutes later headphones, then plugged back in. Surprisingly, I could finally hear audio and emulation of the screen has not frozen, but when I pressed on the record, the record got stuck on "0:00"- and when I pressed the stop button, it gave me an error message saying "unable to save" try save again. " I tried everything several times for a few hours and nothing has changed. Is there something I'm missing... ?

    (TL; DR) so I have to ask. Why play video recording of my iPod QuickTime audio perfectly, but when recording, I don't hear any audio through the headphones of my iPod at all? Audio output when recording is stopped.

    Sorry for the long message and thank you very much for reading and any help!

    Why play video recording of my iPod QuickTime audio perfectly, but when recording, I don't hear any audio through the headphones of my iPod at all? Audio output when recording is stopped.

    Your recording QT X settings say the iPod Touch to divert temporarily the iPod Touch audio pipeline (normally sent to the internal speaker/headphone port) to the Lightning-USB connector to connect to the application of QT X reader when recording. When the registration process is complete, the iPod Touch will automatically reconnect the audio pipeline diverted to the internal speaker/headphone port.

  • Help, please! problem with enhanced vmxnet adapter and Exchange 2003 VM

    Hello

    I recently changed internal NIC our Exchange Server 2003 computer flexible to vmxnet virtual improved, with recommendation of Scott Lowe to modify the *.vmx after taking the inventory server.

    I put the server in the inventory and restarted... then went in through the window / VIC and set a static IP address on Local 2 the new map of the NETWORK, as it was called.

    "I get this message from server: IP address, you have entered for this network adapter is already assigned to another adapter ' VMware Accelerated PCNet Adapter," then it goes on to say that it is hidden from network connections because it is not physically in the computer, there may be network problems and I would like to assign a different IP address... etc.

    Image is attached.

    I tried to do a repair of the VMware Tools, and he did install the vmxnet driver.

    What should I do to banish the network confiict etc. - it is causing people to not be able to use Outlook and disable RDP etc.

    Or how can I get rid of the AMD NIC reference? I don't see it in either Device Manager...

    Thank you!!

    PS Web access for Exchange behaves funny too - messages are sometimes sometimes they aren't - and a few times: "HTTP/1.1 503 Service unavailable" messages

    All this has happened after changing the NETWORK type card - there's no indication anywhere where something like this could happen.

    VMX list section of ethernet, perhaps the error is in the vmx file?

    ethernet0. Present = 'true '.

    ethernet0.virtualDev = "vmxnet.

    ethernet0. Features = "15".

    ethernet0.wakeOnPcktRcv = "false".

    ethernet0.networkName = 'network of the VM.

    ethernet0. AddressType = 'vpx.

    Only the added lines were manually names and functions.

    I really need to get this resolved... maybe I should change back to soft?

    I'd be better off using the method KB VMware to change the NETWORK adapter that requires a change to the description of the OS?

  • Help please! Problems with loading external swf files

    I'm scared, I'm new to both Adobe Flash and Actionscript 3.0.

    I'm trying to create a simple site using a couple of different external sovereigns loaded into a main swf file.

    For the moment, in the timeline panel, I have the following code in frame 1 of the layer actions:

    import flash.events.MouseEvent;

    Stop();

    navbutt.addEventListener (MouseEvent.CLICK, shownavbg);
    function shownavbg (myEvent:MouseEvent): void {}
    gotoAndPlay (10);
    }
    home_btn.addEventListener (MouseEvent.CLICK, showhome);
    function showhome (myEvent:MouseEvent): void {}
    gotoAndPlay (66);
    }
    aboutme_btn.addEventListener (MouseEvent.CLICK, showaboutme);
    function showaboutme (myEvent:MouseEvent): void {}
    gotoAndPlay (49);
    }
    gallery_btn.addEventListener (MouseEvent.CLICK, showgallery);
    function showgallery (myEvent:MouseEvent): void {}
    gotoAndPlay (76);
    }

    var bgLoader:Loader = new Loader();
    stage.addChild (bgLoader);
    ("var url: URLRequest = new URLRequest("Background/sitebackground/Main.swf ");
    bgLoader.load (url);
    stage.setChildIndex (bgLoader, 0);

    Then, in the framework of 76, I have the following code:

    removeChildAt (0);
    bgLoader.unload ();

    In section 77:

    var galleryLoader:Loader = new Loader();
    stage.addChild (galleryLoader);
    var galleryurl:URLRequest = new URLRequest("test/ZenGalleryDemo.swf");
    galleryLoader.load (url);
    stage.setChildIndex (galleryLoader, 0);

    Stop();

    The idea is that, when the file is loaded, the 'sitebackground/Main.swf"flash loads on the stage. Then I want to delete this flash and load a different one when I click on the gallery_btn. So, when I click on the gallery_btn, he plays frame 76, theoretically unloading the Main.swf and the loading of the ZenGalleryDemo.swf in its place.

    For the moment, the Main.swf loads perfectly and works great. But when I click on the button to the Gallery, he jumps to the frame 76 and plays the Main.swf. It does not load the file ZenGalleryDemo.swf...

    If anyone has any ideas, I would be really grateful!

    Thanks in advance

    It's just a glance and reading, but the problem may lie between these two lines... look closely...

    var galleryurl:URLRequest = new URLRequest("test/ZenGalleryDemo.swf");
    galleryLoader.load (url);
