How to write the magnitude values from a SVFA FRF VI to a file?

[ksurdi]

Hi guys,

  I am trying to write the mag, phase and coherence values from SVFA FRF VI to a measurement file. I somehow cannot get it to write to a .lvm or a .txt file so that it can be used for further processing in MATLAB. I have attached my VI for reference along with a sub VI that is required. Please this is very urgent for me. I would greatly appreciate the help. Thank you very much!!

First, it is a Saturday.  So there is not as much activity on the forums.

Second.  What is it not doing?  It looks like you basically have a 2-D array of data going to the Write Measurement File Express VI.  Do you have the one button pressed to enable wiring?

There is a lot of unusual data manipulation going on there like the array to cluster, to unbundle.  Why not just index array to get the first data point?

Put some probes or indicators on some of the wires to make sure you have data coming from your subVI and going through all the manipulations to the Write Measurement File VI.
