Description Usage Arguments Value See Also Examples
PMOD can produce .voistat files with the average model values by ROI for its voxelwise binding potential (BPnd) models, such as Logan, SRTM, etc. This function reads the .voistat file and returns a data.frame with the ROI as rows and the model value as the column. Optionally, the ROIs can be combined into larger ROIs if ROI_def is specified, just as with TAC loading.
