Converting data file from TDMS to TXT - time format and headers.

[sts123]

I have this .vi that converts the .TDMS to ASCII. However at the moment the time format is "00:00.000001    5.2041    0.2388    -0.0004    0.9106" for each line.

How can I make it in seconds in scientific format so the data will show as "1e-6    5.2041    0.2388    -0.0004    0.9106"?

Also how can the headers be added into the ASCII file?

@sts123 You can explore the String palette where you will find an array of string formatting nodes. 

The simplest for you is to replace the date/time string with Format into string, and configure for scientific number.

I tired using Format into string, but then the result text file includes time stamp 4 times for each line of data, instead of doing just once.

If the time appears for each channel, then you didn't set the loop tunnel mode to last value.

Not sure what that is. Can you please guide me?
