How do you screen/filter data.

[BB_Herman]

I am reading in a multi column data file. As I read in each row I want to filter the data based on one of the columns, collect the reduced set of data, and then analyze the reduced set of data. For example, when one column of data gets above 20% of a known quantity, I want to keep all this data and reject the data below 20%. If anyone is familiar with HP VEE, this is equivelant to using if/then/else with a gate.

One of the ways this can be done is to modifiy the "Read from Text File.vi" from LabVIEW help with the "Extract Numbers.vi." A sample vi using tab delimited test file is attached.

This file does not have the EOF file error.

Do you have the extract numbers vi?

You can find it in LabVIEW Help under string examples.
