The steps in BV are attached
However, I don't really understand the output from BV...
Lets say I did a fast event related design of 2 conditions: faces and objects.
1. following this guide, after applying deconvolution GLM (5):
A. Can i add the head motion to tthe new Deconvolution Design Matrix?
B. should I run the contrast face / objects only to the the peak of the haemodynamic response?(i.e., if I chose 10 points for the FIR, for the contrast I should choose only 4-8)
I don't really understand how BV calculate this GLM. Is it first find the shape of the hdf of the conditions (face and object) to each voxel, and then apply GLM?
C. should i correct the statistic for a group ? (as there are much higher number of degrees of freedom).
Furthermore, I artificially increase the degrees of freedom- from 2s to a virtual resolution of 1 s- how to correct the statistic?
2. Running a ROI deconvolution analysis- i chose “ROI GLM” , and get 2 plot of the betas,
A. The second plot- after AR(2)- i thought the correction for serial correlations affects only the error (not the beta).
B. I thought the correct way to look at the event related averaging in % change (then calculate the peak or AUC). can i do it with bv?
any advice will be much appreciated
