mesh.ras2crs: Transform surface vertices from surface RAS to 0-based volume...
In fsbrain: Managing and Visualizing Brain Surface Data
mesh.ras2crs R Documentation
Transform surface vertices from surface RAS to 0-based volume CRS space.
Description
Applies the inverse of the FreeSurfer vox2ras_tkr matrix to all surface vertices, converting them from surface RAS coordinates to 0-based CRS (column, row, slice) indices. The resulting CRS coordinates can be used to directly index into a brain volume array (after adding 1 for R's 1-based indexing).
Usage
mesh.ras2crs(surface)
Arguments
surface
an fs.surface instance, as returned by read.fs.surface.
Value
a modified copy of the input surface with vertices in 0-based CRS space.
