What exactly are you having trouble with. In order to change the number of channels, you just need to change the task or what you are specifying for the DAQmx Create Channel. For example, to read the first four channels, you would specify Dev1/ai0:3.

Hello,

You should take a look at the DAQmx Example VIs in the Example Finder. You can find the Example Finder at Help >> Find Examples.  Once the Example Finder opens, double click Hardware Input and Output >> DAQmx >> Analog Measurements >> Voltage >> Cont Acq&Graph Voltage - Write Data to File (TDMS).vi.  You can specify the channels just like Dennis said in his previous post.
