I am trying to grab the y values from DAQmx and timestamps from irig and log them on different channels (y channel, time channel) on a tdms file so I can graph the data in Daidem. However, it gives me a 2515 error at the TDMS write. what am I doing wrong?

Instead of writing to the Group, write to the Channel.

the daqmx "analog 1d dbl nchan 1samp" outputs 16x1 channel sample array with each row being a channel. I tried writing to a channel instead of a group but daidem only recognizes the 16x1 array as samples from 1 channels when I write to group or channel. Labview still gives me the error mentioned above.

Ok, slight correction: supply a channel name for the timestamp channel (leave the group connected).

so the timestamp are now in its own channel and shows up in diadem. however daqmx "analog 1d dbl nchah nsamp" out puts multiple channels in a 16x1 array (chanxsamp) but only shows up in diadem as 1 chan. it looks like it takes the array and interprets it as 1chan nsamp and shows up in diadem as 1 chan. how can I make it interpret it as 16 channels.

Supply an array of names for the channels. There should be 16 names in that array.

Apologize for the delay. Yes that fixed the problem.
