| Hi all, I am a little bit confused about the qdec display. I have some simple questions about two groups A and B: 1- In the question, does the average thickness differ between A and B? How this average is calculated? By the difference between the A average and B average (avgA-avgB) ? The negative values (normally in blue) mean that the thickness (average of B) B is higher than A? 2- I want to analyze lh parahippocampal thickness. What is the difference between insert the values manually in the qdec.table.dat file (like the tutorial) or import ( in subjects - stats data import) the lh_parahippocampal_thickness from aparc? 3- In the question, does the thickness--lh_parahippocampal_thickness correlation differ between A and B? what for instance a positive value mean on display? I only expected results in the parahippocampal area... Thaks for the help, Miguel. |
