Dear FS Experts, I have one group to compare the difference between their preoperative and postoperative after one month. I followed http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/LongitudinalTutorial to process data. I run these command in number 2.* Longitudinal Image Processing*：
1. recon-all –s sub01_MR1 –all / recon-all –s sub01_MR2 –all 2. recon-all -base sub01 -tp sub01_MR1 -tp sub01_MR2 –all 3. recon-all -long sub01_MR1 sub01 –all / recon-all -long sub01_MR2 sub01 –all I am confused about choosing which kind of analysis in the page http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalStatistics And I tried http://surfer.nmr.mgh.harvard.edu/fswiki/RepeatedMeasuresAnova The “rmanova.fsgd”: GroupDescriptorFile 1 Class sub01 Class sub02 … Variables TP1-vs-TP2 Input sub01_MR1 sub01 1 Input sub01_MR2 sub01 -1 Input sub02_MR1 sub02 1 Input sub02_MR2 sub02 -1 … “tp1-va-tp2.mtx”: 0 0 … 1 And I look in one mail in the list, say “one group to use Paird Analysis easier”. http://surfer.nmr.mgh.harvard.edu/fswiki/PairedAnalysis “pairs.fsgd”: GroupDescriptorFile 1 Class Main Input sub04_MR1 Main Input sub04_MR2 Main Input sub05_MR1 Main Input sub05_MR2 Main … “paird-diff.fsgd” : GroupDescriptorFile 1 Class Main Variables Age Input sub04pair Main 24 Input sub05pair Main 27 … “mean.mtx”: 1 0 My question： 1. Are the above several files I set up correct？？There are inconsistent results in them… So which one should I choose?? 2. I found the increase or decrease a subjects had a great influence on the analysis result, how to filter the participants?? Looking forward to reply, and thanks very much! Kind regards, Livia
