Are there LabVIEW programs written for electrophysiology?

Hi,
I'm trying to set-up an electrophysiology experiment, and I need a data aqcuisition program for my patch clamp amplifier. I've reviewed the existing software applications (pCLAMP, CellWorks, Pulse/Patchmaster), but, since LabView is used fairly extensively in our lab I was wondering if there are any existingprograms/VIs written in LabView for data acq in an electrophysiology set-up. I see that NI had something called BioBench for a while, but that they've discontinued it as of April 2009. Does anyone have any ideas? I don't really want to spend a lot of time developing something on my own, especially if there's something already available.
Best,
Chris

Hi Chris,
A number of people out there have developed LabVIEW applications for doing electrophysiology. If you Google "LabVIEW electrophysiology" or "LabVIEW patch clamp" you'll find some stuff.
Here's one promising lead: LabPatch: http://www.ionchannels.org/showabstract.php?pmid=10794680
You can probably contact this person and get them to send you the source code (they say its "free").
Depending on what you are actually trying to accomplish, it may be possible to start with a simple LabVIEW example program and expand from there as your needs develop. Are you needing a "scope" like program that capture relatively fast waveforms based on some kind of trigger condition (stimulus/response) or continuous acquisition of spontaneous activity? We also have an application called "Signal Express" which can you started very quickly and can be easily customized to do on-line processing - worth taking a look at: http://www.ni.com/signalexpress/whatis.htm
Here's a simpler URL for our Biomedical User Group: http://ni.com/biomedusers
Good luck!

I can not create an Installer, After install the Vision Builder Demo and then uninstall it. I can not create a Labview installer anymore, it asks me for a Vision Builder Installer, even if My Labview program does not have nothing to do with it...

Hi Shada this can happen if you are including additional installers to your installer for example DAQmx. When you are doing this the installer has to include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder it updated MAX, so when your installer is trying to Include MAX, its asking for the source where it was installed in your computer in this case Vision Builder.
Here you can cache the information so its not asked again, or you can download a newer version fo DAQmx, so it will update MAX and change de dependecy.
You can find more details about this issue in this KB:

Using APT ActiveX methods to create a labview program for BPC 203 3 channel Benchtop Piezo controller

Hi Everyone,
I am really very new to Labview and i am in great need for some help.I am assigned a task where i am supposed to create a labview program to control or moniter a BPC203 3 channel benchtop Piezo controller. I created a program with the help of the instructions provided in the APT-Labview guide provided by Thorlabs.But th program doesnt run . Whenever i try to run it i get the same error which says that "Control HW Communications disabled".I have attached a snapshot of the error message.So i tried to create a small program in labview which would read the volage output.Even there i got the same error message.I suppose there is some mistake on my part which i am not able to correct due to the lack of proper knowledge.Could anyone please help me to solve this problem.A slight elaboration would be highly appreciated.Also i think the error lies in the use of invoke node with the get Voltage output method. I am not sure whether the parameters i have provided to the invoke node are correct.Any help of any sort would be highly appreciated.

Hi
I had the same problem today. However, I noticed that the piezo controller has 3 channels with separate slots and they are packaged in the same box. Therefore the whole box has a serial number, probably something like 71822280, and this is written with large letter. Now, in order to communicate with any of the channels, this does not help, but one needs to communicate directly with the interested channel and they have thier OWN SERIAL NUMBERS.
For example channel 1 (my X direction in the nanoMax stage) has serial 91822281, Y has 91822282 and Z has 91822283. So try looking if you have the right serial number Hopefully you found out this yourself but this might help others, I took me3 hours to get this thing working when I started to plug-in the cables and everything.

How do I make a labVIEW program for a linear CCD camera?

Hi, I'm pretty new at LabVIEW and I'm having a hard time figuring out how to connect my linear CCD image sensor (Toshiba TCD1304AP) with my computer. I know I need a DAQ device, what would work best for this particular CCD? After I got that connected, I need to create a LabVIEW program that displays the light detected by my CCD. Does anyone have a similar program or template I can use as a model? Any help would be appreciated. Thanks.

Hello,
I'm not sure the type of signal that is generated as an input to a DAQ device. This could either be an analog or digital input. The signal type will determine how you make your program in LabVIEW. You will also need to correlate the signal level to the light detected. That will be determined by your sensor. I don't have any programs or templates for this, but if you look at the basic analog or digital input examples, you might get a good starting point for DAQ device programming.

Is SilverLight compulsory for running a Labview program?

Hi,
I am using a computer on which Silverlight isn't installed (the microprocessor doesn't have SSE instructions so I am not able to install it). While installing Labview 11 I got a message saying SilverLight isn't installed. I will test my labview program tomorrow (recording analog inputs with a Labjack U6 unit (usb connexion)).
Could anyone tell me if in this particular use of Labview (recording analog inputs + savind data to a file) SilverLight is compulsory?

LabVIEW program crashes after running for few hours

Hello,
I am doing some experiments at the moment which are supposed to last for 18 hours.
Basically, I use a LabVIEW program to control a power supply through a LabJack U6 DAQ. I am currently using LabVIEW 8.5 on Windows 7.
In order to do that, I use a laptop where everything has been disabled such as power management settings, network access is off, windows updates are also off...
As far as I know, the computer can't turn into sleep mode or just shut down (I'm a 100% sure of that actually).
But last night, I started an 18 hours experiment at 5 pm, and when I came in this morning, the program shutted down by itself. Fortunately, the power supply is still providing the voltage I want, but I can't figure out why the program crashes.
When I start the experiment, it also automatically starting saving data in a spreadsheet file (I guess the size of the file should be 36 MB), so it might be a problem of memory access or something.
I really don't know what could have cause this crash, does someone have an idea?
I saw some other threads similar to my problem but I am not running an executable, I am running the front panel directly from the editing mode.

Hi,
thank all of you for your quick answers!
@Josborne : I do not have an error handling in my program. Actually you can look at my program in the attachment file. This is my first LabVIEW program so I've never dealt with error in and error out function... Moreover, what is a log file exactly?
@Johnsold : Yes, I am building an array continously growing over time. Actually, my program stops saving data when you hit the "STOP" button, it doesn't write into a spreadsheet file through a period of time, that is something I eventually need to correct.
@LabJackSupport : I can try to reduce my time step, so far it's 100 ms. I have a problem with disconnecting the USB cable from the computer though : for no reason, if I just unplug the connection between the LabJack U6 and the computer, my power supply will just go providing 157 Volts! And for my experiment, this is something we don't want to have so we just leave it as it is now. Disabling some part of the program is a good idea, I can try it
Thank you for your answers

LabVIEW program for HP 4194A Impedance/Gain-Phase analyzer

Hi All,
I was wondering if anyone has a labview program already written for a HP 4194A Impedance/Gain-Phase analyzer.This instrument measures the impedance,capacitance,dielectricloss etc as a function of frequency.The problem is I have to write down each and every reading. I was wondering if anyone already has a program written for extracting the data and storing in a excel or a txt file.please post the program if you have it.
Thanks
Manoj

Here is an example. It represents some of my early work, but it is functional. With this one, you can get specific readings, or the whole sweep.

Password for labview program

Hi all,
I am developing a labview program for a high
power microwave device. The final program will
be running stand alone on a pc attached to the
microwave device in a laboratory. To ensure
safety, I am wondering if I can set up a password
to the labview program at start up so only
authorised people can use it? Or if there is
other way to do that. Any comment will be
greatly appreciated.
Thanks.

Hank

I am pretty sure that you can do that by using a case loop outside of
your main program. You can set it up so that user(s) will have to
enter a string (which would be password) before he/she can get to the
front panel of the main program.
Within this vi, you can have an array of strings such that users can be
given different passwords (or level of authority) for more security.
After the user enters the password, you can compare the user input by
using equal function in the comparison palette (make sure the password
list is case sensitive or stuff like that or you'll have to convert all
the user input string to either upper or lower case if you want to save
some trouble). If the result of comparison is true, then they can get
into the main program, or else the program will quit.
You can also put in looping structure to make it more fancy such that
each user can be given say 3 chances to enter the correct password...
If you want to go really fancy, you could also try to put in a data
file that stores all the passwords in binary format (requires a little
conversion, of course) in a directory of the target machine that you
know exist (say WINDOWS or WINNT), and include the data file as part of
your instalation disk content, point the installation destination to
that directory. In your password program, find the target machine
operating system and then look for the file from there.
Hope it helps. If you have any questions, please e-mail me at
[email protected], and I'll try to e-mail you a copy of my code.

Can any one please tell me how to write labview program for data logging in electric motor bike.

Can any one please tell me how to write labview program for data logging in electric motor bike. I am going to use CompactRIO for getting wide range of data from various sensors in bike. I need to write labview program for data logging of temperature, voltage and speed of the bike. Can any one help me?

Yes, we can.
I think the best place for you to start for this is the NI Developer Zone. I recommend beginning with these tutorials I found by searching on "data log rio". There were more than just these few that might be relevant to your project but I'll leave that for you to decide.
NI Compact RIO Setup and Services -> http://zone.ni.com/devzone/cda/tut/p/id/11394
Getting Started with CompactRIO - Logging Data to Disk -> http://zone.ni.com/devzone/cda/tut/p/id/11198
Getting Started with CompactRIO - Performing Basic Control -> http://zone.ni.com/devzone/cda/tut/p/id/11197
These will probably give you links to more topics/tutorials/examples that can help you design and implement your target system.

How do I use directional PDA buttons in LabVIEW programs?

Hi all,
I've been assigned to get a LabVIEW program to work on a Palm PDA with LabVIEW 7.0 and palm PDA module 7.0. I am basically totally new to LabVIEW, and my possibly very simple problem is, the PC program requires input from a serially connected number pad for the 8, 4, 5, 6, and 2 keys which are used as four directions (8, 4, 6, and 2) and an enter (5).
I am trying to rewrite the input vi to use the directional buttons and middle enter button on the PDA itself but am having trouble figuring out what to use. I am using a PDA simulator because of the PALM OS5 we own. The input demo vi example provided will not build for PDA because of size so I am unsure of how to approach this. Another thing is, we have LabVIEW and PDA module for pocket PC 8.0, and a Dell Axim PDA on order. From what I understand off of this website, the latest PDA module has example button vi's. I would still like to figure out the way to do this on 7.0 so I can have a better understanding of LabVIEW. Eventually the program's endgoal is to be used on a PDA and inputting with a bluetooth keyboard, but we are going step by step right now.
I guess my biggest questions are, how do I assign the directional buttons on the PDA in my program, and will this differ greatly when we switch to 8.0 and pocketPC.
Oh and I did try to look at the example asteroid.vi but from looking at the input subvi, still couldn't figure out how they assigned the buttons.
Thanks,
Stephen

I can't help with any specifics (no access to the PDA module at the moment and I didn't use the buttons anyway), but I would like to say that it probably would make a big difference if you used LV 8. 7.0 was the first version of the PDA module and was extemely limited and problematic (it didn't even have a tab control). 7.1 was somewhat better and I understand that 8 is even better (although still very limited and buggy).
I also remember reading about several differences between Palm and PocketPC and I think you will generally be better off with the PocketPC as it's related to windows and will probably support more stuff.

Charting data from text file in LabVIEW 5.1 for Windows

I am having some difficulties trying to figure out how to plot a chart with
data from a file. I would like to be able to read data from a text file
into a chart using LabVIEW 5.1 for Windows. I have looked in the help
within the program and online. I have also looked in the user manual and
the book "LabVIEW for Everyone". Could you please give me specific
instructions on how I would construct the program to be able to do this.
Thank you.

Hi Ellie,
It depends on how data is stored in that txt file. Usually you load the data into an array either using or , the array if necessary and send it to the graph indicator in required form. If you want a more detailed answer, send me a sample data file ([email protected]).
