Hi all
I have a basic design efficiency question.
I want to report the efficiency of two model designs using 3dDeconvolve.
What metrics do I use to compare the models? Do I use the signal +baseline condition number (higher the better) and the matrix inverse average error (the lower the better)? Interestingly, both my models have similar numbers for these metrics but one of them (predictably) has highly correlated regressors. In such a situation, does one take into account the latter too?
Also, FSL computes an efficiency score (< 1.5 or 2 % is efficient, I believe). How does this compare to the metrics that AFNI provides?
Thank you for any advice.
Regards
Solana
