Hi!
I have done twice the analysis of amygdala segmentation (dev 7 version) with exactly same way. The volumes do not correspond each other and there is approximately 2mm3 difference in volumes randomly in either direction.
Is this normal or is it something to do with the dev 7 version? Should I be worried?
Thank you!
Best, Reetta-Liina Armio
Dear Reetta-Liina, Is this on the same machine, platform, etc? Cheers, /Eugenio
Yes, all the specs are absolutely the same, same machine, same platform etc. No parallelization.
Thank you for the help!
Best,

Dear Reetta-Liina, After discussion with Koen Van Leemput, I believe I know what the source for these differences it, and it should be fixed soon. Having said that, I wouldn’t worry too much about a 2 cubic mm difference between two runs. Cheers, /Eugenio
