Hi everyone,
I have had a pretty thorough look through FSL JISCMAIL but to no avail, so thought I would ask the group.
I want to compare functional connectivity of a PD cohort with controls using a parcellation of the thalamus and confine my search to target ROIs in the cortex. I am fine with the creation and registration of masks etc.
I have performed the following:
1) Preprocessing using MELODIC and ICA denoising - via FIX
2) Voxelwise individual GLM using timseries extracted from parcellations - via FEAT (I tried using pre-threshold cortical masks here)
3) Higher-level statistics on Feat directories from 2) controlling for (demeaned) age and sex
I am concerned that the data that gets passed from 2) up to 3) is the total cope image and is not confined to the pre-threshold mask region that I incorporated.
Is there anyway I can perform 3) just with the thresh_zstat images produced from step 2)?
Or can someone suggest a better approach to compare my groups confining my search to certain cortical regions (which I have masks for in example_func space)?
Thanks for your time,
Conor
