Dear fsl users,
I have 30 T1 pairs (baseline and follow up) of controls scanned with Siemens
scanner and 21 T1 pairs scanned with GE scanner
My patients consist of 23 pairs of Siemens scanner and 18 pairs of GE scanner
After longitudinal analysis i want to continue with the use of randomise and
localize differences between controls and patients.
I supose that the first step is to use grouped matched controls and patients
(23 Siemens and 18 GE controls as one group and the second group 23 Siemens
and 18 GE patients). Is my assumption correct?
I'm quite confused on how am i gonna set up the contrasts and the design
matrix. Should i consider my case as an Unpaired Two-Group Difference
(Two-Sample Unpaired T-Test) and set up my contrast files as it is mentioned
in the corresponding part of the help page of FEAT or my case falls into the
case of Paired Two-Group Difference (Two-Sample Paired T-Test)?
Thanks in advance
Antonios-Constantine Thanellas
