read.fs.morph | R Documentation |
Read vertex-wise brain surface data from a file. The file can be in any of the supported formats, and the format will be determined from the file extension.
read.fs.morph(filepath, format = "auto")
filepath |
string. Full path to the input file. The suffix determines the expected format as follows: ".mgz" and ".mgh" will be read with the read.fs.mgh function, all other file extensions will be read with the read.fs.curv function. |
format |
character string, the format to use. One of c("auto", "mgh", "mgz", "curv", "gii"). The default setting "auto" will determine the format from the file extension. |
data, vector of floats. The brain morphometry data, one value per vertex.
