Hello,

I have ran my data through the default recon-all processing stream and am planning on analyzing ventricular volume and cortical thickness. I was wondering whether I need to use the Qdec to complete the ventricular volume and cortical thickness analysis, or can I export the data (txt files found in the stats folder) and complete the analysis on any statistical program such as SPSS or STATA?

you can export

I also noticed that Qdec needs to have the data smoothed before analyzing cortical thickness or other surface information. Why does the data need to be smoothed after being ran through recon-all and before analysis? Does the smoothing just need to occur if I am running the analysis via Qdec or do I need to complete the smoothing before analyzing the data on any statistical program?

The data does not necessarily need to be smoothed, but people usually do because it improves stats. But I thought you were doing an ROI analysis based on the first question

Thank you in advance for your help!

Best, Tamara
