Modify calculated channels after logged using VI logger

[Thomas Crowne]

I used the VI logger to log several channels of calculated data. Unfortunately, I found that the zero used was quite different from the actual zero found. What I now need to do is edit the logged data in the VI logger (if this is possible), and then export it again after addition/subtraction. If this is not possible, I need to find a way to edit the exported data (add an offset to each column). thank you!

Unfortunately, it is not possible to change the logged value in the VI Logger measurement database afterwards, or before you would have the channel values exported because the measurement database is a "streaming" database which is designed for high-speed logging to harddrives. The architecture of the database is different from a relational database. It does all kinds of fast memory paging to files with a sophisticated algorithm which is propriatary to National Instruments.

The only way to manipulate your VI Logger data is to export it to a spreatsheet or to DIAdem and do the manipulation there.

Hope this helps.

PS: VI Logger 1.1 is just release, and one feature should be the better integr
ation of for DIAdem. Check it out: News Release of VI Logger 1.1
