StdDev for AimsVoiStat
The content of the output file has changed for "StdDev". What is calculated now? Is it the standard deviation over the VOI? What was calculated in the previous versions? The difference is huge between the results... Thank you for your reply!

This seems to suggest the stdDev was wrong before (in all your earlier studies!)... but I don't know more about it.Change 13797 by maroy@maroy-shfj on 2005/01/19 15:49:54
