Here is an example to get you started.  I don' t normally do this, but I used DAQ Assistant to make it easier on you.  You will have to double click on the DAQ Assistant and set it up according to your hardware.  The VI will take a reading every 10mS (100Hz rate), plot the reading using a guage, and quit after 30 seconds.  Then output arrays are formed with the data for each channel.  You can modify as needed.  The VI is in LV2009.

Doh!  Too slow.

wow...thanks a lot tbob...i just needed this...i didnt know it was so simple..i was so lost especially in converting one form to another....could you tell me one more thing...how can i improve the vi inorder to write what all data its recording???

is the ouput contain signals from all the channels..or is there any specific order while spliting the data???

thank you very much...

[chenda]

if i try to store the data like as given in the attachment..is it possible to write data from all individual channels??

[tbob]

If you do it that way, only the data from the last loop iteration will get written.  Just build a 2D array with all the outputs and write that to the file.

Please let me know how your experiment turns out.  I'm an avid guitar player, and pretty good at it even if I do say so myself.

thanks a lot mate..there is small correction in that loop...its not 30 its 300...i forgot to tell in previous post...am so happy that guitar players are very much intersted in my project....there a huge support from my uni also..am a drummer, but i chose guitar project as the modified guitar was available....i will run that vi tomorrow and test it....and will tell you how was it :)......

cheers...

What kind of transducer are you using to pick up the pressure?  Where is it being placed?  What if the player bends the string to curl up to a higher note?  What about fret board taps.  Now its my turn to ask the questions.
