tdms file write 1d array data

[Timothy 123]

Hi,

I am using the tdms write vi. When I wire data into this vi as a 1d array, I am only able to create a channel group control. when I create a channel name control, the wire between the control and the input to the vi becomes disconnected. Thus the channel name becomes untitled in my tdms file. Is there a way to name this channel name instead of having it being called untitled.

Thank you,

Tim

If you wire a 1d array, the "channel name(s)" input switches from 1d array of string to scalar string. Wiring a string control/constant should do the job.

Tim,

Perhaps you are/were in the same situation I was in this morning.  I had a 1d array of doubles that I wanted to write to a TDMS file; in the array were four values I wanted written to four channels, not one array to one channel.  I solved the problem by wiring each of the doubles into four 'build array' functions and the outputs of those into another 'build array'.  The result was a 1-d array of 1-d arrays, each of which had only one value.  See the attached picture.

I hope this helps.

Jim,

I think these are two different problems - storing a single channel from a 1d array versus storing a single value for multiple channels from a 1d array. You might have an easier time wiring your 1d array to an array bundler with just one input and then do a 2d array transform. The result is the same, but the solution scales automatically to whatever your number of channels is.
