Question about qsiprep's `output-resolution`

Software Support
1

If the dwi data is acquired in a manner such that the voxel size is not a perfect cube e.g., 2 x 2 x 3mm, should i use the smaller (2) or bigger number (3) for the --output-resolution parameter? This is assuming i only intend to analyze the scalar maps and not run any tractography/fixel pipelines

Also am i right to say that higher output resolutions would increase the qsiprep’s completion time?

Hi @gerardyu,

You would most likely want to use the higher resolution (2 mm). And yes, this will increase output data size and compute resource usage.

Best,
