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). |

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).
