What is the difference between TDMS open and TDMS Advanced open?

What is the difference between TDMS open and TDMS Advanced open? The help file just mentions that TDMS Advanced open doesn't create the index file. But apart from that, are there are performance improvements?

Thanks!

Hi Karthik1024,

TDMS Open Advanced lets you access more advanced features of the TDMS file format while reading or writing data.  More information about the difference between TDMS and TDMS Advanced VIs can be found in the index of LabVIEW Help under:

TDM Streaming VIs and functions-> using

There are some specific performance advantages, but it really depends on what you are using it for.

TDMS Advanced Open primitive itself doesn't make performance difference (or not yet, to be more accurately 🙂 ). However, with Advanced Write/Read on the "Advanced TDMS Palette" , you can gain specfic performance improvements when recording and replaying data.

Thanks for the replies. I'll check them out in the manual.
