How to open a .MAT file in LABVIEW
Hey everyone,
I currently have a .MAT image file which I would like to open in LABVIEW to apply some image filters. However, I am unsure as to how to open the .MAT file in LABVIEW. Ideally I would like to be able to open the .MAT file without using matlab, and it seems the only way to accomplish this task is through the mathscript node. I have attached an example of the image im trying to open, as well as the LABVIEW program which I would like to use on the image. Thanks for the feedback! =]

Hi Boiler,
1) Do you have a choice in the format you export your data from MATLAB?
"ASCII Format
Complete the following steps if you want to import or export data between LabVIEW and the MATLAB® environment, the process is straightforward as long as you are using ASCII format.
From the MATLAB® environment to LabVIEW
To save a vector or a matrix Xin ASCII format with tab delimiter, enter the following in the command window or m-script file in the MATLAB® environment:
>>SAVE filename X -ascii -double -tabs
This creates a file whose name is filename, and it contains the data X in ASCII format with a tab delimiter.
Import the file into LabVIEW using the Read From Spreadsheet File VI located on the Programming»File I/O palette.
2) Have you tried using the mathscript node? Did you get any errors?
"Binary Format
Complete the following steps if you want to import or export data between LabVIEW and MATLAB®.
From the MATLAB® environment to LabVIEW
To read a .mat file in LabVIEW would require a VI to parse the file. This may be easier if each variable is saved to a separate file.
" -- this was done here, no ideas if it still works,
I want to read a Matlab MAT file into labview
Hope this helps, James

How to open an external file in Labview?
Hi, Who knows how to open an external file in LabView? I want to open an .UDL file(data link API) which is a dialog window letting me input correlated database information, but I dont know how to open this type of file in my LabView Program.
Thanks.
RedA UDL is technically a text file, so you could open it with "Read Characters from file", put the result string into a string control, edit it and save it back using the "Write Characters to File".
UDLs however have their own configuration dialog embedded in the Windows OS. You can use this dialog in your LabVIEW application. The attached VI shows how to create a new UDL. You can edit an existing UDL by switching the method node to PromptEdit and wiring in an open ADO connection reference.

How to open an excel file from labview?
I tried to use "open file" vi from File I/O -- Advanced file functions to open an excel file in LabVIEW. Why the excel file wouldn't open after I run the program?
In addition to ActiveX, you can also manipulate Excel data files using the Windows ADO interface - a technique that is more robust, faster and IMHO easier. Do a search on the forum as there have been several threads within the last week or so discussing this very thing.

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

How to print a pdf file from Labview
Hi,
Does anyone know how to print a pdf file form Labview. I need to be able to point on the pdf file and to print it.
Activex examples doesnt seem to be working it always displays an error, on every PC that I tryed to run it.
{"code 3005" ,,,"Automation Open: Object specified is not creatable in Display PDF in Dialog.vi"}.
Thank you for your help.
Regards,
Jenia.You can use the "System Exec.vi". The command line should have the following structure:
"<Path to AcroRd32.exe>" /t "<Path to document>" "Printer name"
For example"
"C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe" /t "C:\myreport.pdf" "Tektronix Phaser 300i"

Help opening a .mat file
Hi,
I am new to labview and need some assistance trying to open a .mat file for further analysis (example file attached). The file formate is level 5 and I believe the data is in arrays. I do not have access to confirm the structure but have been told the layout of the data i need to access follows the following structure: MotionFile_walkaround -> Actor_50_human -> Segments -> Sacrum -> Pose.
I have successfully read the header and found that byte swapping is required. I have downloaded the Mat-File IO library but have had no success in reading the actual data set beyond the header but assume this is due to my inexperience with both .mat files and labview.
Any help would be greatly appreciated.

walkaround.zip 1527 KBHey doofus13,
When reading your .mat file, created in The MathWorks, Inc. MATLAB® software, I recommend using the MATLAB® DataPlugin found here:
MATLAB® DataPlugin
http://www.ni.com/example/29178/en/
Then, you can use the Data File Viewer function to view all of the data in your file. Any data that can be seen in the Data File Viewer can then be extracted using the Data Storage API. I looked through the file you provided and was able to view and extract the data contained in the file using the Data Storage API so it should work fine for you.

Hope this helps!

How to open a local file from javascript in a jsp-page
Hi
I have created an iview from a PAR file. In the par file I have a jsp-page with some javascript code. From the javascript coe I want to open a new window with an Excel file.
I have tried window.open("c:
test.xls", "test_window"), but it doesn't seem to work. I have created a small HTML page locally with the same command and there a new window opens with the Excel file.
If I change the local file path with an URL it also works.
Any idea how to open a local file ?
Thanks
/JakobJacob,
I'm not 100% (but 99,9%) and it has to do with security ristrictions of the browser not allowing to have local workstation interation from the web. This is ofcourse very dangerous if the browser would allow it... So therfore it is blocked. What if somone would point to a file/executable that formats your drive so for that reason it is not allowed to have web interaction with a local file. Only with Java Applets this is possible but still with many limitations, and what I remember Google Gears and Adobe Air do have some limited web 2 local file interaction... So best and most simple solution you are left with is pointing to a url instead of a file on a c:\ drive.
PS The reason why it works when you start the html from your local PC has todo with the fact that the browser detects that the html is not running in the web at that moment therefor allowing the access.
Cheers,

How to open a .pse file in photoshop elements?
Hello,
All my previous files were saved as (.psd). Somehow, one of my photoshop elements projects was saved as a (.pse). I can't open it. How can I re open this file and continue working?
Thanks in AdvanceA PSD is the standard working file for Photoshop.
A PSE is a project file for Photoshop Elements. These projects are multiple pages. If you are working with a PSE on Windows, there will be a folder along side your PSE that contains a PSD file for each page of the PSE. If you are missing this folder, you won't be able to open the file. The PSE file itself is just instructions on how to open the PSD files as pages of a project. On Mac, all of these files are wrapped up in a single container. -
