Dear all
I have some ASL data aquired in two runs per session. For further analysis, I would like to combine these two runs. It is my understanding that runs are best combined using a fixed-effects analysis. However, I can not provide varcope files needed for this analysis.
What would be the best option to proceed? Simply taking the average of the runs using fslmaths?
I would be very happy about any advice.
Thank you in advance
Hannes
