I’d better start right away… This is my problem this time:
I want to do some analyses with LabView. Analyses on frequency spectra.
I got raw data from some force measurements. It’s a measurement with an high sample frequency so there are a lot data points. Normally the measuring file is an .smr file. But I can also save it as an .txt file. I added a .txt file. The .txt file contains over 210.000 separate measured values.
I found out that this .txt file might be to big to read into LabView. When I cut the measure file into pieces I get the same signal as on the measuring program (which is NOT in LabView). I got the feeling that it eliminates values within between.
I’m using LabView 7.1. Could somebody please have a look at this problem? Just to make sure that I can use the big data txt file, because I’ll have to analyse over 130 of them, so cutting it into pieces is not a good option!
I added a big and small txt file!
Many thanks in advance!
With the Read From Spreadsheet File function, I can read either file with very little noticeable difference in the time it takes to read.

I still don't have any problems. The large one takes about 3 seconds to load on my pc. Exactly what problems are you having?

I get a look a like graphic, but than flattend at the top. So it's a sort of block wave as you wish.
It looks like you have a problem with localized decimal point (options...front panel). The small files contain a comma as decimal seperator while the large file contains a period, so you might only get the integer part depending on your localization settings.
What country are you in?
