What kind of resolution are we talking about? The resolution parameters control the greyordinates space and the final volume space.

I don't think there is currently a way to use that variable to represent a non-isotropic resolution. However, there may be few (or no) steps that actually interpret that variable as a number and generate a new volume space using it, and instead it mostly just uses that string to look in the global/templates folder for matching filenames - if they happen to be non-isotropic, it would probably just use them. Finally, though, the FinalfMRIResolution probably needs to match the CIFTI grayordinates space being used, and if you want to compare to HCP data, you need to eventually wind up in the 91282 grayordinates space, which specifies 2mm isotropic voxels in MNI space. You might as well do that upsampling early rather than late, so that you don't need to generate new pipeline templates.

I am attempting to use the HCP preprocessing pipelines to processing resting state data which was acquired with a lower resolution than HCP. I notice that the FinalfMRIResolution variable expects one number as input. I have two questions about this. 1. Is this in reference to one particular resolution direction (X,Y,Z), if so which one? 2. If the pipeline expects an isotropic acquisition, how does one enter in an anistropic acquisition? Thanks!
