• Convert TDMS in TXT

  Hello

  I'm trying to convert a TDMS file to a TXT file.  I want to:

  1 convert the DataSet properties (file)

  2 properties of group conversion channels

  3 convert any data.

  The TDMS "sc1616.tdms" file is attached below. The joint "convert TDMS.vi" unable to convert only a data group. I want to convert all the data. The TXT file will be as the attached "sc1616.txt".

  Any help will be appreciated.

• Medium-sized columns in table

  I borrowed this VI from another thread, that works perfectly for what I'm trying to do.

  http://forums.NI.com/T5/LabVIEW/convert-TDMS-to-LVM/TD-p/738286/page/2

  What I'm trying to do is save some tension, keep it in a PDM and a file LVM (which makes the VI above).  The issue I'm running into is I would like to than the converted file of LVM to view an average of all the samples taken for each colum/channel.  In other words, just have a row of the average of the sample instead of several lines of all samples.  Given that I did not write to the origin of this VI, I don't understand how it works and how to change it to the averages just write in the file LVM.  I was hoping someone could show or tell me what to do if it isn't too much trouble.

  Sometimes, a quick search of the forum is all you need, for example from here.

  

• How to convert one or more files LVM of large file TDMS (500 MB, 32 M samples - 2 channels)

  I would like to be able to read at least 4 million lines of data total 32 million lines at a time. The TDMS file has given for 2 channels and no time data. If I can convert TDMS files in one or more files LVM, I can read large files of LVM using the JMP software.  I'm using Labview 2009. Please provide suggestions.

  Thanks in advance. Best regards, Manish (Univ of a to z)

  Hi Manish,

  For your problem with is .tdms to .lvm, take a look at this forum and This example of community.  I checked out, and in my opinion, he should be able to work well for you in regards to creating multiple files .lvm from single .tdms file.  The only thing that could be a problem is the time requirement to enter all in LV, and saves data to several files, but you will encounter when you work with large consumed data.

  I would also suggest that you take a look at tiara if you are searching by analyzing large data sets.  The program is designed to manage large sets of data and make the analyzation on the data.

• TDMS of MDF time stamp conversion error / storage date time change

  I fought it for a while, I thought I'd throw it out there...

  Let's say I have a file TDMS which has a channel of labview time stamp and thermocouple 2.

  

  I load in DIADEM, I get this:

  

  Perfect!  But now let's say I want to save the PDM as a MDF file so I can see him in Vector sofa.  I right click and save as MDF, perfect.  I started couch and get this:

  

  The year 2121, yes I take data on a star boat!  It seems to be taking the stamp of date/time storage TDMS as starting point and adding the TC_Timestamp channel.

  If I change the channel of TC_Timestamp to 1, 2, 3, 4, 5, 6, 7 etc... and save as MDF, I get this:

  

  Very close, 2012!   But what I really want is what to show of the time, it was recorded what would be the 10/09/2012.

  The problem is whenever I do like recording, date storage time is updated right now, then the MDF plugin seems to use it as a starting point.

  is it possible to stop this update in TIARA?

  

  Thank you

  Ben

  Hi Ben,

  You got it right that the MDF use written the time of storage to start MDF that is updated by DIAdem when writing time. We are working on this and will return to you, if there is no progress.

  To work around the problem, you can try convert TDMS MDF in LabVIEW storage vis.

  Something like the following, you can write your start time of measurement to the MDF file.

  

  Hope this helps,

• a faster way for PDM-to-Excel conversion?

  I connect my packets received using blocks PDM, since it is suggested that IO low is the fastest. Since I need data in formal Excel, after my experience, I run a small code that uses 'Reading file of measure' and 'Write in the file of the measure' blocks to convert TDMS to Excel.

  This conversion takes too long, for example 15 minutes from port of 1 million bits of PDM for Excel (I connect packets in their binary form, of 1 and 0). I have attached the VI conversion.

  I have 2 questions:

  1. does anyone know any faster way for the conversion of PDM in Excel?

  2. I need the block 'Reading files measure' in my conversion code since the packets received are saved in TDMS in the form of a single vector, and I need to convert this very long vector in a matrix where each line corresponds to a received packet. Is it possible to make connecting TDMS in the form of a matrix, instead of one vector? This can be slow down my code much.

  Thank you!

  Hi filipfilip,

  Have you considered using the TDM Excel add-in? You can then save the resulting Excel workbook and get the desired file format.

  More information can be found here:

  http://www.NI.com/white-paper/4906/en/

  There is a solution on this post on the forum too which can allow you to do this automatically. I don't know how much faster it would be than your current method but I think it would be interesting to give it a go.

• Convert/import to Excel TDMS

  So I a few LabVIEW code what newspapers to TDMS very well.  I installed PDM Excel add on Excell 2007 and it imports the PDM very well and it looks good.

  What I want to do now is instead of having just I want file PDM, as with the equivalent XLS.  As if I imported the DDHN in Excel and then save the workbook in XLS or XLSX.  So I wanted to import the PDM file programmatically, get the active workbook from Excel and then programmatically save the active workbook in XLS or XLSX in the same directory as the original PDM.

  I have problems with the first step in my plan.  I see here there are a few details on how to call import TDMS using ActiveX, but when I use it I get an error.  Call ShowAboutDlg or ShowConfigDlg work fine, but when I call the import it I get a "an unknown error has occurred: 0 x 80004003" I think that it is an invalid pointer.

  The VI that I used to try to import a TDMS file is attached.  Recorded in 8.20, importing TDM 3.1.0.25, running with Excel 2007 on XP SP3. Thank you.

  EDIT: The VI is pointing to a TDMS file that comes with LabVIEW 2009, this path may need to be changed.

  Thank you ykdoubles, your VI has been very useful.  With he was able to accomplish my goal to be able to convert to PDM to XLSX with Excel and add it on.  Here's what I came up with for anyone who is interested.

  If you have Excel 2003 it may not work, or you may just need to update some of the calls.

• TDMS convert - to-file with the same name TXT

  Hey,.

  I'm working on a VI to convert my data PDM in TXT. My original file is large enough, so I first use a VI to split this file into smaller TDMS files of a few hundert. I found a beautiful VI to run the online task that I adapted a bit (see TDMS to TXT Converter.vi), for example, I added a timer function to give a precise departure time. The problem, I am now face, is that the program does not address TDMS files in order while the TXT file numbers are given successively - so I can't assign the TXT files for TDMS files. I tried to extract the TDMS file names and use them to name the output TXT files, but I don't know how the data type to overcome conflicts (see TDMS to TXT Converter_Version.vi). You have any ideas on how to solve this problem?

  It is useless to the folder in the list where you do the the file path for the text file.  You already have the file that you want to place the data and the appropriate file name.  Just so use the path to build and wire the result in the file Create/replace.

• FFT waveform (file converted from Matt file lvm) - how to overcome the error dt < = 0?

  Hello

  I use a lvm file after conversion of Matt file. I wanted to get the fft spectrum. I get this error message this dt waveform<>

  How he overcome?

  I have attached the matte file and the vi that I used.

  Best regards

  The Forum is a bit special files that can be attached. Creating a zip file often works. Sometimes, you can change the .txt extension. If you change the extension, please indicate in your message which was the extension of the moose.

  It seems that data in the file has a time column and a column of amplitude. The LabVIEW waveform data type is a cluster of a table of amplitudes (Y), sampling interval (dt), from the time (t0) and optional attributes. That's what the power spectrum VI requires as input. The t0 values is not used if the default is fine. the value of dt can be calculated by the difference of the two adjacent values in the time column. Given that the first value is equal to zero, the second value is equal to dt.  Use the primitive to build a waveform of the palette of waveform.  Expand it to view the dt element.

  In the VI attached all lines is an indicator that contains your saved default file data. Graph XY plots that data.  After subtracting the way to get rid of a continuous component, the data is converted to a waveform. The power spectrum is calculated and displayed using the same VI as in your program. It also uses extract several Information.vi tone for the frequency and amplitude of the main peaks in the data.

  Interestingly, the lower frequency of the spectrum a harmonic of 60 Hz while the tops are almost sharp space 4 kHz ~ 100 Hz apart.  The broad peak near 2.1 kHz does not seem to have noticeable components to 60 or 100 Hz.

  How to avoid the Type of dynamic data (DDT)? Stop using screw Express! For reasons known only to EITHER screw Express a deliver their outputs via the DDT. Except when you open the block diagram of the express VI, there is no way of knowing what the underlying data structure on a thread of DDT.

• 5 converter does not recognize the partition LVM on Oracle Linux 6

  I have two physical servers running Oracle Linux Server release 6.3 64-bit.  They each have a partition/Boot which is ext4 and the rest on a LVM partition:

  / dev/map/vg_cleveland-lv_root / ext4 defaults 1 1
  UUID = 3d37688e-305 a-4974-9bb7-f02232b78790/Boot ext4 defaults 1 2
  / dev/map/vg_cleveland-lv_swap swap swap defaults 0 0
  tmpfs/dev/shm tmpfs defaults 0 0
  devpts/dev/pts devpts gid = 5, mode = 620 0 0
  Sysfs/sys sysfs defaults 0 0
  proc/proc proc defaults 0 0

  vCenter Converter only recognizes the / boot partition in the ' Data to copy "section"Select volumes to copy.

  If I leave before the conversion fails when you try to reconfigure the virtual computer.  I looked in the user guide and google a bit but I can't seem to find why the LVM ext4 partition is not recognized by the converter 5.

  Yes, it seems that the output has changed in more recent versions, so we need to update converter accordingly... but always the solution to workaround with the older LVM version on the source (how old?) should work...

• NCL TDMS Converter

  Hey guys, it's going to be my first post so please forgive me if I forgot to provide crucial information.

  Is what I'm trying to do with LabVIEW to create a VI that uses the examples of OR pre-built "Display NCL Logfile as"Target-BUS"Frames" to write the contents of these logs in a single TDMS file so that you can view several newspapers in a single file.

  So far, my approach contains the real top level VI NCL_Viewer. You will first need to provide a file path or a directory, in both cases the VI lists each .ncl file in the specified folder and calls the "display logfile...". "- VI for each of them.

  The Subvi then determines if the NCL file is of type CAN, LIN and FlexRay and she turns the respective table but - different from the original NOR-VI - is not write in a PDM file but a table hint. This, however, leads to ~ 500MB including the PDM file and the corresponding index - ratio 50: 50 - what is bad, I know and also takes about 10 minutes to write. Defrag reduced this Mo ~ 25 PDM and<1MB>

  FIRST QUESTION: Can I prevent this somehow? I'm not sure on how to use buffering in the case, but given the fact that defragmentation can reduce the size of the file, I have to believe it must be possible to create smaller files in the first place.

  In addition all these logs to a TDMS file would be kind of chaotic display, as TDMS allows only two levels of internal file structure. That's why I set up my own new group names in dieting 'Filename-ID' (e.g. CAN_01-963 963 ID in the first newspaper CAN). I did my own version modified DDHN-Viewer-VI incorporated so that it splits the name of group in CAN_01, 963, and creates a new tree like:

  CAN_01

  -963

  -Channels

  Even if this isn't the way the TDMS file is built, I can do look as if he was.

  SECOND QUESTION: I keep coming with a corresponding number of entries of CAN_01 number of connected on this BUS, rather than just a single entry, listing all the different ID of ID. What is wrong here?

  As to help you reproduce my problems I downloaded all the screws in my project, but also a NCL-Logfile for each type of BUS.

  I thank in advance and forgive me if any transition is difficult to read - English is not my mother tongue.

  PS: Check the path access-controls/constants so that they are valid for your PC.

  Just to close this topic, I got the second problem solved and the first omitted.
