• How to find the sampling frequency to read the measurement file

  Hello

  I would like to find/extract the sampling frequency of a .lvm file.

  Right now I am using the VI 'read file of measurement' and my data charge fine and all, but I need the frequency of sampling for certain calculations.

  I know the header of the file .lvm that the sampling frequency is 1613Hz, but I want to get this automatic information from the open file .lvm.

  Tried to find an express vi that could give me the answer, but I could not find a

  I'm sorry if this question already answered, but I could not just to find the answer.

  I hope you understand what I'm doing!

  Thank you

  Kind regards

  The timing is part of the production of signals information. Never use the functions of the Express, but you can use DDT to and convert to one of the data types of waveform. Waveform components then turns the dt.

• Delta t do not update using write in the measurement file

  I write data to a file that is collected with a dt = 0.005 sampling interval (but no hardware DAC.   I would like to save the data in a file LVM with a column, the timestamp and the second data column, and I use the Express VI 'Write in a file measure' in the following Labview code snippet:

  

  The value of the local variable dt is 0.005.   The delta T is saved in the saved file, but the timestamps don't change the initial value of o, o:

  

  What Miss me?

  Thank you

  I wouldn't really call it a workaround solution. This is the expected behavior.

  Build and write like a table and your waveform will be saved correctly.

  If you are going to write a point at a time, all you have to do is to keep track of what you want to use when you build your unique point to t0 and wiring waveform.

  EDIT: Is the column name 'Untitled' bug your client at all? It would have upset me. You can fix it by set the attribute of waveform for "NI_ChannelName."

• Change the decimal point by point in the writing of the measurement file

  Hello

  I use writing to the extent of the vi file to save data. I can't read the text file in Matlab, I guess that is because the decimal separator is a comma.

  Y at - it than a simple means of LabVIEW to set the decimal separator to be the point instead of the comma? (in writing to measure file vi)

  now, the data is like this 56 897 but I like it in the format 56.897

  Thank you

  Hi simo,.

• What type of file I use to read a large file of data?

  I want to store data in a file and access it later. The data file could reach between 500 and 1000 MB in a binary format.

  I might have some memory problems.

  I didn't need all of the data in memory, only a few data every time that, for my calculations.

  If I use a binary file, I can't read only a few data. I have to load the entire file and then read the data I need.

  Is this correct?

  If I use another type of file, can I read that a few bytes without loading the entire file?

  Maybe a TDMS file?

  I would probably use a TDMS file for this because it could also be read in excel if there was enough - just little more flexibility. But you can also do this by using binary types. You don't have to read the entire file when you use binary files. See below.

• cannot read the source file or disc for install.wim when file copying.

  I'm doing a windows 7 bootable from a USB key, and when copying files every thing goes more except for the install.wim

  I checked there is enough space on the disk, and I also tried copying from disk to my office, same question.

  I tried using the command line to move the file and get an "Access denied" error message, which I believe is the root cause as to why I can't move the file in the first place.

• Error "this file has no program associated with it for performing this action. Create an association in the control panel of the associations' when trying to read the video files on the CD

  Original title: file does not have a program associated with it for performing this action.

  I make a business card CD on Auto Play Studio 8. I have completed the project and burned the cd to test on different computers. When I clicked on the 'Video game' button, I get this warning. "This file has no program associated with it for performing this action. Create an association in the control panel of the associations' Ok I made the proper action to take, and I still get the same problem. I did this on a XP pro, Vista and 7 PC.

  
  Hi NoPCgeek,
   
  1. what program do you use to read the file present on the CD?
  2. What is the format of the file present on the CD?
   
  Before playing the files on the CD, make sure you cross check if you have the right program installed on the computer. If you have not installed the right program, then we recommend you to install the program that supports the file type and use them to read the files on the CD.
   
  You can also change the default program to read this file. The program opens the file only if the file format is supported by the latter.
  See Change that uses default Windows programs

  I have lightroom 6 and just got a nikon d7200, lightroom now reads the tiff file so I can not download my pictures on lightroom

  You really produce TIFF files? If you are, no matter what version of LR read them. Files NAVE, not so much. For NEF files out of this camera, you can either upgrade to the latest 6.4 or CC 2015.4, or you can download the latest free Adobe DNG converter software and use it to convert your files to DNG and import those into LR 5.7.

  Back to TIFF format. If you are trying to import those and get a message that the files cannot be read. You will need to change the permissions on the folder that you copy the image to. Change the permissions if you have read and write access.
