Dear Dr. Frank,

I have done QA analysis using an older version of DSI Studio (I don't remember the version), and the QA values were around 0.78.
Recently, I updated the software and had to add additional subjects to strengthen the sample size. What I noted with the new version is that the mean QA is around 0.27.
 
Do you know why there is a discrepancy in the QA values between the old and new versions?

There is a major change in QA after the 2022 August versions: https://groups.google.com/g/dsi-studio/c/t-kSFxXrGFU?pli=1

You may use an older version to create FIB files (I am sorry for the hassle caused).

Best regards,
Frank

Ah! I saw this email thread before and completely forgot about this. Thanks for your patience.

I'll reanalyze the whole data with new version. No big deal! Thanks :)

One follow-up question, Dr. Frank -  Can I use the old FIB files (calculated using old version) to calculate the (new) QA using the new version?

The NQA in the old FIB file is the QA in the new FIB file.
Hope this helps,
Frank
