Labview is a user-interface based software in a test analysis environment. Can we measure its robustness, user satisfaction? How?

Hello All,

I'm working on a code (vi) in LabVIEW to assist in analysis of data acquired from a ultrasonic probe. Now the data acquired is in the form of text files with a size ranging approximately from 10's to 100's of MB. The content stored is in the form of numbers (amplitudes) captured by the sensor when run across a piece of metal (with flaws in it; purpose of experiment being - flaw detection). To read this data and to orient the position of the flaw I have made a vi (with couple of sub vi's).

That was a background, my question is: If I were to use this software to just read and analyse the data, what is the required amount of automation expected to be done? Can be measure a LabVIEW code in terms of the appearances on the front panel? Can we realise and define user satisfaction?

Ditto that!

A "problem" with Labview. Is that it is very easy for a beginner to make a mess out of thing. Labview itself has in most cases more than good enough robustness. But a poor/bad Labview programming style. Will in most cases take away the robustness. But to blame Labview as development system for this is wrong. The correct thing is to blame the programmer.

Then working with very big text files like you. It is a quite common mistake is to read the full file into the memory. And perhaps on top on this show the text file in a indicator not really needed or even worse some local or global variables. Before you know it. You have used almost all the computer memory. Render your Labview application slow as syrup. And the user satisfaction poor at the best
