Read multi-column data file and do analysis

Hello,

I used Write Labview Measurement File VI with n-signals input to generate a data file containing 2*n columns(time column and data column iteratively). Now I need to do analysis from the file. I'd tried to use Read Labview Measurement File VI to load the data but didn't work. I found that it can only read file with one signal as input and without file header.

What I want to do is to extract specific columns from the file. Some column has special flag values which divide the column into sections. I also need to extract these sections from the column and plot each of them. I know this can be easily done on other data analysis software but is there any way I can do it on Labview?

Thank you
