mni.write.vertex.stats: Write the output of a vertex statistics run to file

Description Usage Arguments See Also Examples

View source: R/vertex_glim.R

Description

Takes the output from mni.vertex.statistics and writes it to a vertstats file using either the new (with headers) or old version of the file format.

Usage

1
2
mni.write.vertex.stats(vertex.stats, "filename", headers=TRUE,
mean.stats=NULL, glim.matrix=NULL)

Arguments

vertex.stats

The results from mni.vertex.statistics

filename

The filename to write to.

headers

Whether to write out header information. If TRUE, then a new style file is created with a hierarchical header; this is the default. If false, then a simple file without headers is created.

mean.stats

The results from mni.mean.statistics run on the same dataset. This information is written to the header if headers=TRUE. mean.stats is NULL by default.

glim.matrix

The glim matrix used with mni.read.glim.file. If passed to this argument then the matrix is added to the header. Default is NULL

# A complete statistical run:
# read the design matrix file
## Not run: gf <- mni.read.glim.file("filename.glim", header=TRUE)
# see if the mean is different
## Not run: ms <- mni.mean.statistics(gf, 'y ~ 1 + V2')
# look at the results of the mean stats run
## Not run: summary(ms)
# run a test at each vertex
## Not run: vs <- mni.vertex.statistics(gf, 'y ~ 1 + V2')
# write the results out to file.
## Not run: mni.write.vertex.stats(vs, "filename.vertstats", headers=TRUE,
mean.stats=ms, glim.matrix=gf)
## End(Not run)
