Synopsis

mris_ca_train [options] hemi canonsurf annotfile subject1 [subject2 ...] outputfile

Arguments

Positional Arguments

[options]	-sdir, -nbrs, -orig, -norm1, -norm2, -norm3, -ic, -sulc, -sulconly, -a, -t, -v, -n, -?, -u
hemi	hemisphere: rh or lh
canon surf	canonical surface file
annot file	annotation file
subject 1 [subject 2...]	subject(s)
outputfile	classifier array output file

Required Flagged Arguments

hemi canonsurf annotfile subject1 outputfile

Optional Flagged Arguments

-sdir <subject dir>	specify a subjects directory (default=SUBJECTS_DIR)
-nbrs <number>	neighborhood size (default=2)
-orig <filename>	specify filename of original surface (default=smoothwm)
-norm1	GCSA normalize input #1 after reading (default: disabled)
-norm2	GCSA normalize input #2 after reading (default: disabled)
-norm3	GCSA normalize input #3 after reading (default: disabled)
-ic <number_priors> <number_classifiers>	(default: -ic 7 4)
-sulc	specify sulc as only input (default: sulcus and curvature)
-sulconly	same as -sulc
-a <number>	number of averages (default=5)
-t <filename>	specify parcellation table filename (default: not written)
-v <number>	diagnostic level (default=0)
-n <number>	number of inputs (default=1)
-?	print usage info
-u	same as -?

Outputs

outputfile

classifier array output file

Example

mris_ca_train -n 2 \
    -t ./my_color_file.txt \
    lh \
    sphere.reg \
    my_manual_labeling \
    $SUBJECTS \
    ./lh.my_atlas.gcs

In this example, mris_ca_train would look for a file named lh.my_manual_labeling.annot in each of the subjects listed in $SUBJECTS label dir (e.g. $SUBJECTS_DIR/$s/label), and also assume that a file named lh.sphere.reg existed in the surf dir of each subject.

The -n 2 option tells it to use 2 feature dimensions for classification: curv and sulc (which is what is used by default).

The -t ./my_color_file.txt option will read in the file my_color_file.txt and embed it in the atlas, so that mris_ca_label will put it in the automatically generated .annot files, so that later, tksurfer (and other things) can read it in.

The format of the my_color_file.txt file consists of a set of lines like:

1   Corpus_callosum     50      50      50      0

where the last value (0, in this example) is not used, and the 50s are r,g,b (red,green,blue) values. They must match what is in the annot file, in which each vertex is given the value: r+(g << 8)+(b << 16).
