Dear MH
How to use fslmaths and fslstats to perform spatial correlation between two sets of masked voxels ?

Note though that 'fslcc' includes ALL the voxels (including any non-brain 0 voxels) in its computation of the correlation, which isn't really what you want if you are trying to rigorously quantify spatial similarity. In that case, you can either calculate
the spatial correlation of a set of masked voxels from first principles (using a combination of fslmaths and fslstats calls), or do it in matlab or using an AFNI function called '3ddot' (which allows you to supply a mask).

HI - you might find it a lot easier to do this with fslcc (or in matlab). I'm not sure about SPSS.
Cheers.
Dear FSL group,
We want to reshape seed-based RS connectivity maps into one dimensional vectors, in order to calculate Pearson correlation coefficients between vectors in SPSS (for quantifying spatial similarity between connectivity maps). However, we are wondering which FSL
utility and which options we should use for this purpose?
Any assistance would be more than welcome!
All the best,
Mark
