Hello FSL folks,
I was wondering about a phenomenon that I just noticed and which worries me a bit. I was extracting individual subjects' time-series from ROIs using fslmeants with the goal of running ANOVAs. The input files from which I got the time-series was filtered_func_data. The time-series were organized into blocks of three speech production tasks (30 time-points per task). After sorting task-related time-points into different columns in Excel and running a simple correlation, I noticed a near-perfect correlation between them (I mean, 0.999998).
Does anyone have an explanation for this? Is this normal?
Thanks!
Nicolas
