Hello All,
I used fsl_sbca (seed-based correlation analysis) to create correlation maps.
I would like to create tstat maps from these correlation values. Would it be correct to calculate the tstat as follows:
tstat = r * sqrt[(n-2)/(1-r*r)]
where r = correlation value for each voxel i; and
Is n the length of the eigen variate time course? In my case, that would be 200 time points extracted from the filtered func dataset.
I can calculate this using fslmaths, but is there another/better way?
Thanks,
* ba
