Sort data please help

That's what I'm trying to do. I have a file periodic_chan3.bin which is sampled values of three channels of periodic signals in interlaced format. The data is stored in binary format (long of floating point of the double procession) DBL and big-endian representation. I am reading the file and draw all the three waveforms on the graph of a waveform. The data has been saved from time zero, with a sampling frequency of 100 samples per second. Then I scale the x-axis of your waveform graph so it displays the time in seconds.

So I try, on the wave of the chart to create three sets of cursors and cursors to display the average value of each of the three waveforms. The color of the cursor Y for a given signal average must match the color of the display of the waveform on the chart. For example if the graph of the signal is displayed in red the cursor there shows the average of this signal must be red.

What happens when I do not open the file I see a white contour mesh a sine graph, a graphical square and sawtooth chart. I can't seem to trace the three waveforms seen clearly with the three above-mentioned distinct colors. I can't seem to sort correctly and represented as mentioned above.

I would also help with the calculation of the average or expected from each of the three periodic waveforms.

Attached are the files please help. Pgm4 is the VI, and periodic_chan3 contains the data that needs to be sorted.  I'd be very happy if somene were able to fix the and submit the changes so I can see how it works. Thank you.

Edit: I get an error that says periodic_chan4.bin "is not a valid extension of an attachment" so I'm not able to uplad it. Is there a way to othe I could download it?

Xtasy26,

In your post you mention that you try to view 3 averages of waveform, however your code is showing that you are broadcast 4 values. This might be the reason why your getting the different forms of data. Instead of an array of all the waveforms 1, then a table of all 2 waveforms and a waveform table 3, you get a mix of all three in each of your waveforms.

To calculate a moving average or mean that it is actually an integrated in the example in BT sound finder called "running Avereage.vi calculation"

You can also view the attachment to see Multiple waveforms channel displayed on a single chart.

  • BlackBerry smartphones wipe all my data PLEASE HELP

    I tried to back up my phone with the blackberry desktop manager. I continued my password (I couldn't remember exactly what it was, I went online and to reset to the last attempt). I received the confirmation email that it has been reset, so I returned the new reset password. He said it was bad anyway and started wiping my device. EVERYTHING - all my contacts, all my sms, all my work, all emails. I jumped the battery when he was about 6% of the wiping process, but every time I got back on it starts wiping again. Please please please help me, how can I stop this? It's my phone, I have entered the correct password, I wanted to just back up my data and now I lose everything instead.

  • Degraded data please help im know if everything lost

    Hi, I recently bought a "new" rn21400 4 unit without drive Bay and two new disks 4 TB Western Digital RED.

    everything has been works well since I've set up three days ago, today I though I would transfer the last of my documents to the nas to my pc (approximately 250 GB of photos and music) before completing about 70% done the unit began flashing data degraded

    When I checked the volumes on the admin page one of the disks is red and when the information arrives he says bad disk.

    It is said with xraid on a raid level 1 I believe that must have 4 TB of backup?

    What should I do? I was really not lucky and got a faulty drive or a simple restart and resynchronization or other difficulty there. There is a lot of data on the nas about 1.2 TB of films, working papers that I really can't lose, ive so them removed from my home pc as I well they have ended safely to the nas.

    Help, please

    RAID-1 provides redundancy backup.

    With RAID-1 when a disk fails and you add a disk to a resynchronization is triggered. This puts heavy emphasis on all disks that the disks must be synchronized by sector. As the disk that was considered to be failed is added in the table it has probably been deleted. If the other drive happens to fail during the resynchronization (unlikely, but possible) then you may lose all your data.

    So if your data is important just store them on an SAR unit. You need a backup to another NAS unit or somewhere else. However, if the primary copy of the data is on your PC then copy on the NAS server is a backup.

    It would be helpful if you could send your logs as suggested BrianL.

    You cannot add smaller disks to X-RAID volume, but you can disable X-RAID and create a second volume, or you can reformat all (for example to do a factory reset) and create a new volume using all four disks.

    Hi all

    I'm not very advanced at complex formulas however using this forum in recent weeks thanks to everyone here, I was able to create the automated collection of amazing data workbook. I searched for the last missing piece, and according to two explanations I've found here so far, that they are too complex for me to understand yet what I am eager to realize I thought was pretty simple.

    If anyone can help me with the formula to be used in these empty boxes, it will make my week!

  • socket InputStream does not get all the data, please help

    I've been doing stuff of network on blackberry for quite awhile, but still using the http connection.

    I have to use the socket for a piece of my application connection, but could not do the work.

    This code is what I do

    String url =

    "socket: / / ' + rmserver + ': ' + rmport;

    Socket SocketConnection = Connector.open (url) (SocketConnection);

    socket.setSocketOption (SocketConnection.KEEPALIVE, 1);

    OutputStream = socket.openOutputStream ();

    InputStream = socket.openInputStream ();

    send something here using outputstream

    int

    If (f > 0) {}

    do somwthing

    }

    AV is always 0.

    I don't know that my server sends data successfully. I run the network packet capture tool etheal on the MDS Server, I can see given reached MDS Server, but they never come to my device app.

    The outputstream works very well, I can send data from my application and my server code gets all of them.

    Where should I check? If it is http, I can turn on the debugging http on MDS log and see all network traffic, but for the socket connection, data packet is not connected (or I missed where it is).

    Is someone can you please tell me where I should go to understand why?

    Please try the suggestion to remove the check mark on InputStream.available.

  • 9 bit RS485... missing data please help!

    Hi guys, I'm running a 9 bit RS485 .vi and although I get successfully most of what I need through with no problems (using the trick of mark/space parity), there are a few problems.

    It's to do with the headers, I put in place; both are 5 characters and although I can see all 5 present on our scope, LabVIEW is only showing the last 3 characters and I can't work where the first 2 are or how to make them appear.

    The funny thing is, one of our PC does a similar thing but will dispay just the FIRST 3 characters of the header, not the last 3 as on our other 4 PCs. All of our PC using 2 isolated, NEITHER Port RS485, even if we use a few different versions of LabVIEW 8.2 in 2009.

    Any help or advice would be much appreciated!

    See you soon,.

  • Synchronization between two databases with only 2% of the data; Please help me

    Hi all

    I have two oracle databases in 2 different servers PROD and TEST instances. the two databases are in gr 10 2 in linux servers.

    My PROD database contains about 300 GB of data and is dedicated for production area.
    My Test database is dedicated to Spanish test for PROD database. (small server in terms of space and RAM comparing to PROD db)
    I would like to synchronize every week TEST db with PROD db with only 2% of the data and all the structures
    Could someone tell me, if you use a datapump export I can import only 2% of the amount of data and the structures ot theere is another way to do it?
    Thank you very much

    best regards,
    W

    I'm not really sure what you're talking about. There is no option, expdp and impdp x % of the data, is that? And if Oracle can sovle repositories inetegrity (PK, FK), it cannot be assumed which tables are lookup table (to be entirely exported) and can not assume the logical data integrity.

    How could a routine walk-run? Inside, Indoor walk or another run? I do this routine outdoors with Gps first so that I'm not kidding my calibration data? Help please and thank you!

    Hello

    Choose indoor walk or run Indoor (it does not matter which) to an indoor walk-run routine.

    Even if Apple Watch does not currently offer as a workout interval training, choose one of these allows the most appropriate data sources (which are the same for market and short) to use to track your training.

    If walking or running, the accelerometer is used to estimate pace and the distance (allow your arms swinging naturally) as well as the frequency heart sensor for the estimation of calories burned.

    Run or walk inside will not affect your calibration data. Calibration is based on the GPS of the iPhone data and is only held during the outdoor walking training or race outdoors when the iPhone combined is taken along.

    Try restarting your phone. Sometimes it shows data that brought them "disappeared". To do this, hold down your power button for about 15 seconds, until you see BlackBerry on your screen. Do not release the button until you see that without taking account of any other thing you see before that.
