How do I use adaptive LMS filter with waveforms?

[xrahulx]

In the attached image file and VI, I am reading a .lvm file which contains abdominal ECG (AECG). AECG contains both maternal and fetal ECGs i.e. MECG and FECG respectively. I'm trying to input AECG and MECG to the LMS FIR filter so that I can get FECG as the error signal, e(n). In my VI, e(n) is coming out as a 16-Bit Double but I want it to come out as a waveform. How do I go about it?

NOTE: Since this forum doesn't allow uploading .lvm files, I have share in Google Drive here. You can use this file to run the attached VI.

Step 1. Dont use the express VI. It makes assumptions about the data that don't appear to be valid.

PS: The lvm is just a text file. Change the file extension to txt and upload away.
